The solar photovoltaic works on the principle of photovoltaic effect. It is the physical and chemical property or phenomenon in which electromotive force is generated in the non-homogeneous materials with the illumination of light of a specific wave length. This effect produces voltage and electric current in a material upon exposure to light.
Solar panels convert sunlight into electricity through a process known as the photovoltaic effect where the energy from photons is absorbed by semiconductor materials, generating electron-hole pairs. The movement of these charge carriers creates an electric current that is then collected and utilized as electricity.
