Is it possible to make a biosollar cell, that is, to use chlorophyll instead of silicon...?

Question

and if it is possible what will be the benifits?

Answer 1

Not really. If we were interested in ATP instead of electricity, it might work, but even then we'd have to supply this solar cell with a fresh supply of CO2 and H2O. In this case, Physics has a better answer than Biology (the photoelectric effect)
