Solar 3.0: This New Technology Could Change Everything 

It's nice that he was honest about the main disadvantage, longevity.

solar 3.0 next season they said...

now to wait for Arc 3.0

This is not what I expected for Season 17 bungie...

Can't wait for season 17

solar 3.0 confirmed for next season lets goooooo

This was a great video. As someone who is going to college for materials science, it was cool to see the concepts brought up in ways that make it easy for a layperson to understand, and also very cool to see the guy from the company be honest about the downsides to perovskite solar cells.

Dude bungie’s rework is gonna change the world

Hey I love that guy you interviewed being straightforward and honest. The big issue is stability and I'd love to find out more about that.

If it ain’t about my dawn blade idc lmao

Now we are just waiting on Arc 3.0

Fantastic video, both your enthusiasm and optimism for this new developing technology radiated through the script!

I truly appreciate the honesty in this video presentation. They ask hard questions and point out both the positive and negative attributes of this technology. Over 50 years of R and D with solar and we are still waiting for a significant break through. I do hope that Perovskites prove to be that breakthrough.... The solar cell and the battery still have a lot of improvements to go through before they become a viable, national energy sources.

Wait… this is not Destiny

I have been pro R and D on solar, but against mass implementation, as we are going too fast before the tech is ready on that scale. This could truly be a game changer. Keep the R and D going.

I really hope solar 3.0 brings two icarus dashes back for pve atleast

Very well written piece. Twice, so far, he mentioned something I was questioning. This one was when he said the two chips were samples used in the lab. I was thinking when he first talked about them, they seem a lot closer than 10 years away.

This wasn't what i was after when I searched up Solar 3.0, but I'm glad I chose to watch it regardless. Great video!

This is definitely something I hope becomes commercially available soon because I inted to heat my house using Geo-thermal and I'd like Solar Panels (with w/e batteries I can get for energy storage for cold/night time usage) to be what is giving the geo-thermal unit all the energy it needs to operate at 100%. Not needing to burn wood or use oil/propane etc. is a dream of mine but living in NH I worry about how many solar panels I'll need to get so that (even in Winter time) I never have to worry about having enough power to run my geo-thermal unit. I haven't done any research into how much solar panels are going to cost me but, as long as I can afford it, I have no doubt I'll be needing dozens for year round powering/usage.

Energy from sunlight is a no brainer. Keep up the good work!

The most beautiful thing in living long enough is that we see more new things and get the chance to use some of them. Who would have thought of such technology ?

Fantastic presentation on a solar technology I didn't even know existed. I always love hearing about newer and better technology. In my heart I know you'll solve the problems surrounding early degradation. Cheaper more cost effective so what's not to like? Scientists like yourself always amaze me. Thank you for everything you do to make this world a better place to live. Energy costs have a lot to do with making that happen. Know that you're very much appreciated!

Thank you for asking all the right questions

I’m currently doing the nabcep Solar course and this information was really helpful

"1% of the material compared to current cells, so it's gonna be cheaper!" Companies will still find a way to charge us double the cost of existing cells just because it's new.

Outstanding presentation. Super interesting details direct from the company, including their manufacturing process

I am excited to see where this goes and really want to even be able to create one of these items. Seems nice. Very nice. Just need the knowledge of how they work and how to wire them.

A common problem with thin film types is that high temperatures cut the lifespan. For the western states silicon crystal holds up best, so far. If only they can come up with a thin film type that will stand up to extremes in temperature.

Love it. Keep up the great work, brother.

From past few years, I've been hearing of things that will revolutionize power production. Yet to see even one available commercially.

bungie is getting really creative with these subclass updates!

Love the simplicity yet the complexity in his explanations. Can’t wait to see what happens next. Q: Could Vanta black with is light adsorption affect the efficiency of the tandem and attract more sunlight to the tandem while finding a solution that will dissipate heat away from the tandem bc vanta black absorbs almost all light therefore I’m thinking heat too.

The quality of the animations is amazing!, keep up the good content! 👍

Extremely well explained and illustrated. Very easy to understand by anyone no matter the level of scientific knowledge. Well done and keep up the good work!

If the tech ever evolves to the point it needs to be...that would be awesome. Good luck!

Great video! Keep up the good work!

Mr. Jean does an excellent job of explaining Swift Solar's approach. I also appreciate his candor on his current priorities for scaling production, his manufacturing and testing methodologies, what the limitations currently are (longevity and environmental ruggedness), the current market applications, and his priorities in broadening its utility by addressing the longevity issues.

Cant wait for arc 3.0 now

Hi there, I have never seen like this before. Looks like it will be very useful for the future.

Graphene could serve as the transparent electrode. Graphene is almost a one-atom-thick superconductor and can be applied using chemical vapor deposition (CVD). CVD is currently the front running process for making graphene. Even though there may be lifetime limitations for Perovskite solar cells, they are so cheap to make and produce so little pollution, they can be considered disposable.

Information well presented with a Refreshing "depth-investigation" for the novice. Easy to undrestand yet complex. Well Done.

The initial video depicting the electron-hole interaction when the P and N-type materials are brought into contact was something you might consider donating to a University for the 1st course of Solid State Device physics. It would also be useful to incorporate the discussion of the Fermi level as part of the discussion to round out the band gap discussion. Good luck in your venture but many practical problems to overcome but your video shows you have a grasp of many such issues.

Loved this video, very informative.. can you make one on semiconductors?

very well explained hope to see more news soon :D

Awesome video. Keep up the good work

You'd "only" need 100x100 miles of solar panels...not accounting for weather conditions, power storage, power transfer, growing demand, maintenance, etc. You'd also need batteries the size of city skyscrapers....a whole city of them. You'd also need to replace ALL of that every 10-20 years.

Very interesting topic and well presented! Good job!

Thank you for this video and explantation, kind regards

He said, "Stability is still a challenge..." IOW, the perovskites don't last very long, much less than 25 years. They won't be able to be used for rooftop or utility scale solar systems until their "stability" AKA lifetimes can be increased to 25 years. If perovskites can be made cheap enough, the sheets might be made to be quickly and easily changed when they lose efficiency.

So informative and I didn't know there was better technology, instead of the existing solar panels systems.

Well done video! Exciting future!! 😎

I'm not sure how I ended up here but this vid was very informative. I've learned alot

Amazing video, thanks for this

I appreciate the level of transparency (ha!) In this video. It didn't feel like hype and lies, but realistic expectations.

That was awesome! Good job!

I'm feeling a lot intelligent compared to yesterday. cool video!

This was a good video and I'm especially happy you went into the challenges it faces although I always end up frustrated not really understanding how they go about improving the poor aspects. Like, what specifically allows for one of these substances to be more durable to heat and how do they go about trying find it? I also find it sort of alarming that this crystalline structure was just found in nature rather than come up with. Is it possible theres an even better structure and wouldn't trying to optimize that be the most important step. I mean, it's possible that all this research into perovskite's becomes useless if some better structure is found so shouldn't we first develop the science around finding the best structure?

Make the sheets easily replaceable and using them will follow. And from that will come the data to iterate the various components. Promising work.

Excellent video! More videos on solar power please!!

hiya, excellect video. Many thanks, as a follow up were there any relative articles I could use as a reference to my research paper?

Given time and further R & D this science has huge potential. These people deserve further funding and encouragement to advance their research. It is mind boggling to imagine the possibilities that await us with this possible breakthrough

This got me much more interested and educated than severals hours our lessons on perovskites for material science. I was surprised there was no mention of the Lead (Pb) as most issues with perovskites used to be that we didn't know how to do lead-free perovskites crystals. I would have liked to know more about the toxicity of these coatings

At a 1/15th cost of solar panels, at 20 year lifespan seems reasonable at least on a consumer level which are more less the same life span as most current solar panel tech, let alone roofs, vehicles, and most applications. It seems that really isn't an issue. And if it's better for the environment with more abundment materials cost.. it seems like they're almost ready to launch.

This is genius and will quickly be adapted to many industrial fabric uses! I am amped!!

I need this for my van, as I am overlanding in Africa at the moment. I can even do some real world testing for them👊🏿👌🏿👍🏿

"What if I told you about a...." Yeah, extreme distrust mode activated.

Wow, renewable energy is such an important topic! I recently came across the Segway Portable PowerStation Cube Series and it seems like a fantastic option for outdoor enthusiasts like us. With its massive capacity, waterproof technology, and fast recharging capabilities, it could be a great solution for camping or as a backup power source for our RV. Definitely worth considering!

Can't wait for this tech to be widely available

Cool to see more efficient solar power models being researched. Finding efficiency is the crux of engineering.

Great info guys!

Amazing! Great work!

Very excited about seeing work being done to make solar thinner and more efficient. I’m not a scientist, but have thought about this type of “panel” for phones, drones, cars and more would be great! A s solar Silpat mat!

Perovskite solar cells have been in the news for a very long time... and not a single residential product available yet. You cannot claim it is cheaper until you have a working product that lasts. To make it last, more expensive components may be required - which means its not cheaper anymore.

"Stability and Degradation: Perovskite solar cells have demonstrated competitive efficiencies with potential for higher performance, but their stability is quite limited compared with that of leading PV technologies: They don’t stand up well to moisture, oxygen, extended periods of light, or high heat. To increase stability, researchers are studying degradation in both the perovskite materials and the contact layers. Improved cell durability is paramount for the development of commercial perovskite solar products. Despite significant progress in understanding the stability and degradation of perovskite solar cells, current operational lifetimes are not commercially viable. Mobile markets may tolerate a shorter operational life, but stability during storage (prior to use) is still a key performance criterion for this sector. For mainstream solar power generation, technologies that cannot operate for more than two decades are unlikely to be viable regardless of other benefits. Early perovskite devices degraded rapidly. A few years ago, typical perovskite devices would degrade within minutes or hours to non-functional states. Now multiple groups have demonstrated lifetimes of several months of operation. For commercial, grid-level electricity production, SETO is targeting an operational lifetime of at least 20 years, and preferably more than 30 years. The perovskite PV R&D community is heavily focused on operational lifetime and is considering multiple approaches to understand and improve intrinsic and extrinsic stability and degradation. Efforts include improved surface passivation of absorber layers; alternative materials and formulations for absorber layers, charge transport layers, and electrodes; and advanced encapsulation materials and approaches that mitigate degradation sources during fabrication and operation. One issue with assessing degradation in perovskites relates to developing consistent testing and validation methodologies. Research groups frequently report performance results based on varied test conditions, including variability in encapsulation approaches, atmospheric composition, illumination, electrical bias, and other parameters. While such varied test conditions can provide insights and valuable data, the lack of standardization makes it challenging to directly compare results and difficult to predict field performance from test results. This affects the entire perovskite research and development (R&D) community, independent of any specific research area, material set, or stability improvement approach."

I am working with a few groups developing and testing perovskite research cells and mini modules at NREL. There has been a lot of momentum (money) behind this as the new OPV, and efficiencies have shot up quickly. I see some of the newest devices from universities and startups.. there is still a long way to go for stability of these modules and materials

I read about BAND GAP tech about 20 years ago. Technology takes time and a ton of effort. Excited to see where this will go!

I like the idea of buildings producing its own electricity. This can be used for both the operation of the building as well as charging workers cars etc. The main advantage is that this energy doesn't come from the grid. In fact it can top the grid up.

I'm a materials scientist & engineer. Just getting into solar technology out of interest. Excellent presentation . This technology step appears to be X2 decades away from a real commercial application. Carry on the good work. Nano Nano.

I could see huge success with this marketed as a DIY kit. This could revolutionize our green economy, giving financial incentive to those of us who are handy with diy projects.

Excellent reporting thanks!!

When I was working on machines to laser scribe thin film solar panels in the early naughties, all people were talking about was getting the cost down to $1/watt, we hoped thin film was the way we would achieve that, but economics of scale have meant that monocrystalline cells dropped in price far more rapidly than anyone imagined, pricing out cheaper, but lower efficiency, thin film technologies, even Cadmium Telluride (which was horrid to work with, ask and I'll tell you about the extraction system we built). It's really great to see new options, and perhaps Perovskites are the way to bring thin film and BIPV back to the forefront, if the logevity problems can be solved, but even if they can, industry is slow to adopt technologies that don't have a long history already, so I wouldn't be surprised if we had to wait another decade for Perovskites to make any significant market impact.

Good to know people who develop this understand they do not need to compete with silicon panels in how long they will last when they can provide more power cheaper and for less weight. Needing far less material and lower temperature to make them also means the energy cost of making them is far less, meaning they need even less time to recover the energy used to make them than regular PV panels. And the materials are far easier to recycle too. With such benefits these panels would be viable if they just last for a decade or so, and even that is more for people's convenience than actually needing to produce more power over its lifetime. It actually starts to seem like the demand for panels to last 25 years was put up by some people who do not want us to have cheap solar panels...

So, I have actually read quite a few research studies related to perovskite panels. Most of them were from the Institute of Electrical and Electronics Engineers (IEEE). It seems that there are two major issues with perovskite solar panels. One of them was mentioned in the video, but not with a lot of detail. Currently, perovskite panels have an estimated lifespan of approximately 10 years. They did mention durability problems, but didn't really emphasize just how long they are expected to last. They kind of jumped around a bit on it instead. The other issue is related to this, but probably more important. Because they degrade faster, they also leech chemicals, such as lead (and the other materials they are made of) into soil and waterways which has the potential of contaminating our food supply if placed in agricultural areas, and drinking water if runoff makes it into water reservoirs. Some of the chemicals that leech out are not harmful at the low levels that make it into soil and water, but other chemicals used in the construction have not really been tested to determine if they will be safe for humans (or other creatures) at any level if they contaminate our soil or waterways. Lead is not safe at any level, so that is a major issue. The ability to manufacture them at such low temperatures is great when it comes to cost and production related environmental hazards, but it also means that they can begin to degrade at those temperatures as well. I'm sure that is what the people in the laboratory are probably working on tackling, but if something like this gets pushed out too quickly without solving this issue, it could cause a lot more problems that the ones it resolves. Hopefully, they figure something out though, because otherwise, they seem quite promising in comparison to traditional silicon solar panels.

This is science presented in a journalistic style; the advantages and challenges, for the thinking person. Fascinating! Hopeful technology toward renewable energy for sure!

They never ever ask the key question; when can my contractor buy this product at Home Depot? When will it hit the market. This technology has been around for a long time ... still waiting.

One way to improve solar panel efficiency is to install blocking diodes between each of the solar modules within the panel. Conventional panels when just one of 60 sells is shaded will reduce output by as much as 50%. This is because the shade itself becomes a load on all the cells that are receiving sun and the energy is diverted. Blocking diode to prevent the solar cells that are in sunlight from feeding back into the Shaded solar cell.

Really good work! Impressive.

I remember reading in some magazine around 2000 about 2 technologies for solar. 1 was a paint for your house that would insulate the house (low R factor) and allow solar use. And the other was a film for use on the windows that would still allow light to pass through, but let you hook it into a solar system. I was hoping to really see both develop and this looks sort of like #2. I hope it come to fruition.

Back when I was looking at them in uni the big problems with perovskites was the inorganic part is usually a heavy metal cation and the film is usually is pretty water soluble. So manufacturing and end of life recycling is a big deal for them unlike with silicon solar cells.

When "growing" indoors, we always used "High Pressure Sodium" lights for artificial Sunlight and "Metal Halide" for artificial Moonlight .. Works like a charm ;)

Maybe waves/beams of light could be absorbed better if the band gaps were designed to act like an alternating current to reduce reflected light by creating feedback loops. Given the metals can benefit from their light properties, perhaps the colourful oxidised Bysmuth could be strong enough to be used in a pyrovskite layer. It could be a cheaper alternative to Iridium.

Scientist: "This will be produce a much more affordable product." World Economy: "Hold my beer"

These videos about “new developments” are always interesting, but I’ve learned to take them with a big grain of salt. I used to subscribe to Popular Science back in the 1970s, 80s and 90s and they’d always be showcasing some new technology, only to have it completely disappear after that. There are SO MANY things that can derail a technology. Not only does it have to work, it has to be fairly easy to manufacture, it has to be cost effective, it has to be financed and promoted correctly, it has to pass the myriad EPA regulations, and today it has to be recyclable (otherwise the disposal costs become prohibitive. A good example of how a technology can make a wrong turn, is the straight screwdriver and the Phillips screwdriver. Back in the day, they were both competing for the emerging consumer tool market, but the developer of the Phillips screwdriver wanted more money than the straight screwdriver did, and so most people chose the straight edged screwdriver. It wasn’t until much later that the Phillips got any traction.

I look forward to seeing Perovskite solar cells becoming main stream, and hopefully bringing down the cost of solar cell, and improving efficiency on energy generation. It will certainly benefit alot of people then, from all walks of life.

Can you please list the scientific articles and papers you used to make this video? I'm doing my bachelor's in physics on this topic and it would really help! :)

It's great they're being honest with the fact there's issues with the tec currently.

That young man is so inspiring in his explanation. Give another nudge of hope for that generation. Keep it up young man.

Massive cool ! It was interesting to hear that production costs can be greatly reduced but you can bet your life when this technology hits the market it will be more expensive to the consumer than currently available solar panels.

Might be interesting to add an electret below the solar cell to change the band gap of the semiconductor junction. Also a thermoelectric layer below the solar cell cooled by water could increase efficiency and provide free hot water at the same time. Best wishes for success.

One year later we've skyrocketed to 15% renewables. we've got this yall! just keep doing the hard work.
