- Photovoltaic cells, also known as solar cells, are semiconductor devices that convert light energy directly into electrical energy through the photovoltaic effect. - When photons from sunlight strike the semiconductor material (typically silicon), they excite electrons, creating an electric current. - Dry cells, Leclanche cells, and Voltaic cells are types of electrochemical cells that convert chemical energy into electrical energy, not light energy.
Solar energy is converted into electric energy through
