Comments on Light Generated Current


can you please differentiate solar cell operation vs diode operation clearly.
Thank you.

I have question about voltage and light.
Why the voltage is increase when i use reflector by mirror?

Why simulation from a page "Light-Generated Current" different from the page "Bias of PN Junctions"?

The solar cell operating within forwarding bias, right?
