How Do Solar Cells Work? Photovoltaic Cells Explained
PV cells, or solar cells, generate electricity by absorbing sunlight and using the light energy to create an electrical current. 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.
Photovoltaics is a form of renewable energy that is obtained from solar radiation and converted into electricity through the use of photovoltaic cells. These cells, …
