Why do solar cells generate electricity
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. Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.
