This is a really good video. Explains the solar panels pretty well

Exactly what i was looking for, thanks.

so simple...

Why do the electrons move to the bottom of the cell,

and not up?

He he he ... what a stupid vidio. The solar cell they show is UPSIDE-DOWN! Silicon PV cells have the P-type (created with silicon + Boron) in the BOTTOM (it's the substrate ... 99% of all wafers are p-type), and the N-Type (created with phosphorus) is in the TOP. At least they have the electrons being generated largely in the P-type (next to the pn junction) and getting trapped in the N-type region where they're then captured for doing useful work (creating potential - ie. voltage).

excellent video. simple, but informative video. :) keep it up!

@baeronautics This is true that the lost electron from an atom makes it unstable, but the idea of electricity is that electrons are always flowing through a circuit so fast that a metal can be said to have a new electron as soon as it loses the other so there is no need to worry that a metal will react and combust for whatever reason. Plus the cells are sealed behind a casing I believe. But research more into it, I could be wrong, but it seems logical to me that this is why photovoltaics works.
