Abstract

This academic article describes the theories related to energy gap, p-n junction, electron-hole and absorption mechanisms to generate solar cell electricity. Basic knowledge of quantum theory, charge movement with the Fermi-Dirac distribution function in statistical mechanics and hole flow result in the diode equation used for finding solar cell equation and net current. The simple method used to determine the efficiency of the solar cells can be determined by the percentage of voltage obtained on the energy of the photon calculated from the maximum solar absorption value in the visible light range, which suggests that the efficiency of the solar cell is about 20%.
