Yes, I was wondering if anyone was, perhaps familiar with the industry of photovoltaic cells and how that industry is maturing. In particular, how efficient are the best cells available today. I would guess its measured in something like Watts/Surface Area, or some statistic like that. Another question I had was about how the cells capture EM energy. Do they collect a wide band of the EM spectrum, like say Gamma to Radio EM, or is it collecting mainly in say the visible 400-750nm spectrum, or mabye just a single wavelength? Thank you in advance for good answers.
