I am working on simulation of solar cell at national physics laboratory delhi . And this lectr realy help me a lot . Thanks for making this kind of lectures available.
I used to work as a research physicist in electro/optics, developed photocells and also solar cells in 1974, after the oil crisis. My solar cell had already an efficiency of 27 %! The good professor should explain what "p" and "n" junction stands for! "p" means positive and "n" means negative.You give a semiconductor negative or positive doping. There are other semiconductor than silicon. I used CdS, Cadmiumsulfide, very cheap. I also worked with prof. Karl Boer, professor at Delaware University. He build the first solar house in the USA!
+Rolf Niebergall He already lectures at a level in which terms like 'doping' and knowing an excess or deficet of electrons are.... oh, fuck it. You like to hear yourself talk, we get it.
+Kevins Knives First: "fuck it", tells me this person is low class! Explaining terms should be in the first lesson for future students otherwise you do not know what it all means! This , suppose to be , "Lecture 1"! I know, you are not a good teacher.
As by request of local students I am teaching a course in the Physics of solar cells, being no expert in this field, these set of lectures have been really enlightening both for me and my students.
amazing presentation about solar cells. In one hour you get a magistral explanations about basics of semiconductors and their application on solar cells.
This was incredibly helpful and I looked more into your publications which are also very helpful! Thank you for these resources. I am a Biochem student considering electrical engineering as my master's and I am doing a presentation in conjunction with a report on entropy production as it relates to solar cells. A beautiful and relevant application that encapsulates many fundamental concepts in physics and physical chem. And Boltzmann statistics apply here, my favorite!
on slide 13, if you have Po = 10^3 , doesn't that means u have to have 10^3 electrons as well ( from thermal breaking of bond ) in addition to 10^17 electrons due to the doped phosphorus ?
These are helpful but I think there are some mistakes in this presentation. I think these should be improved. Please tell me where I can submit these mistakes.
