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?
The process of how PV cells work can be broken down into three basic steps: first, a PV cell absorbs light and knocks electrons loose. Then, an electric current is created by the loose-flowing electrons. Finally, the electrical current is captured and transferred to wires.
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 standard panel used in a rooftop residential array will have 60 cells linked together.
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.
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.
