# I am a little stuck on an engineering question to do with Photovoltic cells.

Kimbo
I need to calculate how much power will be generated by a solar cell at AM1.5. The cell is 1.5x3.5cm^2.

I know that it is to do with the area of the cell i just don't understand how to work out the power generated without knowing things like the material. Any help would be appreciated.

Don't feel bad; neither can anyone else, not without knowing something about the material etc.

Tell us what "AM1.5" means. If you assume 100% efficiency, how much power can the solar cell generate? And what are more typical efficiencies for solar cells now?
