Question:
How does a photoreceptor cell function?

Replies:
The simplest way of describinng thier function (in other words, giving up just a little bit of accuracy in order to speak english) is that when photons strike the electrons in certain atoms, they may displace the electrons to another nearby atom. Some types of atoms are more prone to having thier electrons displaced than others, so by using two different types of material, you can pick up a little bit of current from one material to the other.
