The material used in silicon solar cells Galium Arsenide isn't an environmental friendly material. For us to have large quantity of solar power the materials used in the solar cells can't be dirty in themselves or the environmental advantage are lost.
A question in my mind is if plants is the ultimate solar cell, cheap to produce, naturally converting solar energy into biomass, sugar and potentially diesel. There are also ecoli based solar conversion.
