Abstract
An important potential application of graphene is as a component of a solar cell. Highly conductive, transparent graphene can serve as one or both electrodes, one of which has to let light into the absorbing region of the device. The photovoltaic action of a solar cell occurs as photo-generated carriers, electrons and holes, are generated in (or flow into) a central region of strong electric field, that sends carriers of opposite charge in opposite directions. In the conventional silicon solar cell, the absorbing regions extend beyond the depletion region, containing the electric field, into the oppositely doped electrode regions, by diffusion lengths L on either side.
