Hello there,
I have information about semiconductors and do know what's doping. Besides I do know how a diode does work at forward and reverse bias.
I do know how a battery causes the depletion region narrow in forward bias or thicker in reverse bias.
Today I read 2 papers about how solar cells do work.
Suppose the light exists and the load is connected to the cell. Now several electrons from the N-side go to the P-side via the load, right?
My main problem is how the cell does work after all free electrons from the N-side go the P-side??
I am not sure but I guess maybe electrons are able to reach to the N-side again after they went to the P-side via the depletion region?
If so, how they do that?? And if no then why the cell generates a for ever voltage when the light exists?
Thanks a lot
