In this article, we'll look at photovoltaic (PV) solar cells, or solar cells, which are electronic devices that generate electricity when exposed to photons or particles of light. This conversion is called the photovoltaic effect. We'll explain the science of silicon solar cells, which comprise most solar panels.
Simply put, photovoltaic cells allow solar panels to convert sunlight into electricity. You've probably seen solar panels on rooftops all around your neighborhood, but do you know how they work to generate electricity?
Solar cells are usually made of silicon semiconductors that can absorb sunlight and convert it into electricity. They are organized into a large frame which is the solar panel.
Solar PV systems generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many photovoltaic cells within a single solar module, and the current created by all of the cells together adds up to enough electricity to help power your home.
A photovoltaic cell alone cannot produce enough usable electricity for more than a small electronic gadget. Solar cells are wired together and installed on top of a substrate like metal or glass to create solar panels, which are installed in groups to form a solar power system to produce the energy for a home.
The main semiconductor used in solar cells, not to mention most electronics, is silicon, an abundant element. In fact, it’s found in sand, so it’s inexpensive, but it needs to be refined in a chemical process before it can be turned into crystalline silicon and conduct electricity. Part 2 of this primer will cover other PV cell materials.
