Does the photovoltaic cell ever deplete? Does this process continue indefinitely?
-
Well done: this is one of best explanations for how solar energy generates electricity. (however I wish that the resolution and audio was clearer.)
-
well parallel plate cap.
-
this is the principle of a capacitor
-
There are a number of inaccuracies in this description ... for example the statement that all mobile electrons are generated in the depletion region, or the visual description showing the holes are immobile and the the electron travels to the one left behind. Also the majority of the resistance is not in the depletion region ... the majority of resistance is caused by impurities throughout the whole wafer ... also a conceptual inaccuracy ... electrons loose energy in recombination, not travel.
-
@sandslash123 this is due to the electric field that the p-n junction is creating in the center. That is why, the only way for the electrons to fill the holes is through a circuit. This circuit leads the electrons to the holes in the positive layer.
-
Waaaaait. Why does the electron goes through the negative side if there is an excess amount of electrons there? Shouldn't it go to the positive side since there are more holes there?
-
amazing ..

I was on this show! I sat on those vectors! (The big arrows.)

Great video. Thanks.
