[0025] The working principle of a solar panel is based on the photovoltaic effect. When sunlight hits the surface of a solar panel, photons are absorbed by the semiconductor material (such as silicon) in the photovoltaic cell. These photons have enough energy to excite an electron in the semiconductor from the valence band to the conduction band, leaving a hole in the valence band, forming an "electron-hole pair". In a photovoltaic cell, a PN junction is typically used to create an internal electric field that separates the electrons and holes and forms an electric current through an external circuit. When a load is connected to the circuit, this current can provide power to devices.
