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.

Do Solar Panels Use Heat or Light?

High temperatures can reduce the efficiency of electricity production, so although the solar panel will absorb both light and heat, it is the light that it wants. This is true of PV solar panels, which are the standard electricity-creating solar panels. However, there are also such things as thermal solar panels that work slightly differently.
