A photovoltaic cell, often known as a solar cell, is an electronic device that transforms light energy into electrical energy. It is a semiconductor device that generates an electric current by using the photovoltaic effect. The photovoltaic effect is the process of converting light into electrical energy. When light strikes a semiconductor, electrons are stimulated and migrate from the valence band to the conduction band. This generates an electric current that can power gadgets. Semiconductor materials, such as silicon, are used to make photovoltaic cells.
