Organic solar cells

Solar cells are semiconductor devices that convert light into electricity. Under illumination, light flux is shined on the solar cells. When the photon energy is equal to or greater than the bandgap of the material, the photon is absorbed by the material, one electron is excited into the conduction band (C B), and one hole is left in the valence band (V B).
