When sunlight strikes the cell, it generates an electric current by knocking electrons loose from atoms within the material. Multiple solar cells are combined to form a solar panel, which can produce a substantial amount of solar electricity. Why is Solar Cell Called a “ Cell “?
Solar cells, also known as photovoltaic cells, convert light energy directly into electrical energy. They are made primarily from semiconductor materials, with silicon being the most common. When sunlight strikes the surface of a solar cell, it excites electrons in the semiconductor material, creating an electric current.
Photovoltaic cells generate electricity when light strikes the panel and is absorbed by the semiconductor material. This absorbed light transfers its energy to the semiconductor, typically made of silicon, which then produces an electric current.
Solar PV systems generate electricity by absorbing sunlight and using that light energy to create an electrical current. Each solar module contains many photovoltaic cells, and the current generated by all of the cells together adds up to enough electricity to help power your home.
