Definition

A solar cell is a fabricated device that converts the sun’s light into electricity. If we want to get right into it, a solar cell takes the energy from the sun’s light rays, by using the colliding light at the photon level to split apart the electron-hole pairs. When the photon hits the pair, they break, and one part goes north one part south. The stronger the sun, the quicker and more this happens. This process is called the photoelectric effect. The following diagram explains.

Fabrication

Once the solar cell is fabricated, that is, once it has been either grown or the layers of the solar cell have been deposited onto each other, and you’re looking at a wafer, the front and back contacts need to be added to give the electron-hole pairs a place to go and complete the photoelectric effect… That is, wires need to be added to allow current to flow!

This is a place where things get tricky and lots of research is being done, because when the deposition of a metal layer onto a crystal is done, at the boundaries between the two materials a resistance exists that is generally larger than the resistance inside the homogeneous material itself. The research is to reduce this resistance with various theories and tricks.

Application

Each solar cell wafer is generally combined into one big solar panel, which is most likely what you buy in the stores. These are usually all wired up, and ready for you to plug into a battery!
