How do they work?

This is a solar cell. These are small pieces and you need 36 of them to make up a
12 volt solar panel. The layer directly underneath the glass cover, is called the front contact grid. It's usually made of metal and attracts electrons so the other parts of the cell can use them. Below that is the anti-reflective coating, and it channels light into the cell and keeps light from bouncing off. Next are the sections of N-type and P-type silicon chambers. In the N-type silicon section uses an element like phosphorus and bonds it to the already existent silicone. This creates a negative charge. The P-type does the opposite it makes the charge positive This piece allows for a element like boron to bond with the silicon inside this layer of the cell. This creates the positive charge. The last piece the back contact made out of metal and acts as a conductor for the whole cell.
