How solar panels actually work?
In: 75
The most eli5 I can think of, is this: You know how electric phenomena can happen in two directions, like, you can use an electric current to drive a speaker, oooor, you can use the speaker and some sound to generate a small electric current. Same thing for a motor/generator.
A solar panel is a device that can convert light into electric current and vice versa. [It’s basically a big-ass reverse LED](https://www.youtube.com/watch?v=6WGKz2sUa0w). It uses the photo electric effect to turn incident photons into exited electrons and vice-versa.
