MIS solar cell—General theory and new experimental results for silicon

The metal–thin-insulator–semiconductor structure recently has been shown to have potential as a simple efficient solar cell. A general theory of these solar cells as well as experimental results for silicon devices optimized on the basis of this theory are described. The experimental devices have exceptionally good open-circuit voltages. Under illumination resulting in a short-circuit current density of 32 mA/cm2, an open-circuit voltage of 618 mV and a fill factor of 0.6 were obtained.
