The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.
Solar panels do not involve chemical reactions directly, but they do rely on the photoelectric effect. When light particles strike the surface of a solar panel, they can cause electrons in the material to be excited and move to a higher energy level. This movement of electrons generates an electric current, which can be captured and used as a
