Sarah Kurtz, Research Fellow at the National Renewable Energy Laboratory (NREL) argues that solar is truly coming of age and answers where photovoltaic technology stands today. And she addresses what it will take to move beyond today’s dominance of crystalline silicon and introduce new technologies which aren’t yet competitive. Finally she offers that it will likely take identifying new applications for new forms of PV, and that the resulting transformation will be deep as well as global.
Sarah Kurtz, PhD, Research Fellow, is a world-renowned expert in multi-junction PV, concentrator PV, and PV reliability. At the National Renewable Energy Laboratory (NREL) since 1985 she is the Co-Director of the National Center For Photovoltaics (as of Aug. 2017).

Thank you for sharing this very useful information, Dr. Kurtz. I thought your insight about Chinese cell manufacturers sharing technological advances, and that being an apparent boost to the whole Chinese solar industry is a refreshing acknowledgement. In this time of climate catastrophe, we should be working with as much cooperation and collaboration as possible. Capitalism and the protective IP that it often produces, will not necessarily aid our collective problem solving.

Even conservative estimates show that we could be adding up to a terawatt per year of solar and wind energy by 2030. We finally there.

As this and last year's talk by Gregory Wilson on this channel show the world needs a lot more than a Terawatt, so we must aim higher.

Gash, I love you guys, how can we stop being opponents (economic) have ever been to a 2nd or a 3rd world country,

Solar boilers are small scale solar thermal, but even using resistance heating instead of heat pumps, PV is cheaper.

Re: Ivanpah's CSP use of Natural Gas, it's my understanding that they did not finalize that system with molten salt. Instead it was built with water heating only. Because the water in the turbine and the whole system does not remain hot for hours all through the non-operational night, natural gas had been designed as a parastic load maintain the high heat needed in the system to resume the next day immediately at sunup. Essentially slow run the plant at night on just enough fossil fuel to make it roar with the sun. Their logic seems to be that using CSP to super heat hot water works, but using CSP to eventually superheat hot water in the late afternoon, means you lost too much solar day to getting the water up to a power generating temp. I would guess this means Ivanpah is a flawed design, and they should have modeled it better before building it. But I don't believe they are simply fulfulling power needs with a Nat. Gas, as the question implied. Either way, a solar plant that can't run without natural gas is pretty dumb. Here are more details: cleantechnica.com/2016/04/25/newly-released-data-indicates-ivanpah-gas-5-percent/

To overcome the surpluses of PV generated electricity would be to create demand or better yet to replace other energy such as oil run vehicles with electrical vehicles. Another way would be to store the electrical surpluses with batteries or desalination plants for water.

But, electric companies are paying low rates when they buy our electricity and a higher rate when you draw it out in the evening. Watch out, folks.

Costa Rica generated 99% of their energy from renewable energy in 2018, only turned on their generation plants for 3 days, living ing CR, I do not see any wind or solar. How does this add up. I love the idea of renewable energy ( being a sailor) but the cost to low income, low tech, everyday people, you sound crazy,

I don’t think you are not sincere, but you are talking way out of reality to MOST of the world
