Abstract
A solar cell illuminated by circularly polarized light generates charge and spin currents. We show that the spin polarization of the current significa ntly exceeds the spin polarization of the carrier density for the majority carriers. Based on this principle, we propose a semiconductor spin-polarize d solar battery and substantiate our proposal using analytical arguments an d numerical modeling.
