Yeh, that seems to make sense. It was the point about the photoelectric effect freeing electrons in the depletion region that I was originally unsure about. Will white light incident on the depletion region definately free electrons from these otherwise stable atoms?
Does anybody know why illuminating an LED with a filament lamp would produce a voltage in a simple circuit with just an LED and voltmeter? I'm guessing it's related to the photo-electric effect, but I have no idea what is actually going on.
If any of you guys could help me out, or point me in...
