OverviewWorking explanationPhotogeneration of charge carriersThe p–n junctionCharge carrier separationConnection to an external loadEquivalent circuit of a solar cellSee also

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.
