ABSTRACT
A solar cell illuminated by circularly polarized light generates charge and spin currents. We show that the spin polarization of the current significantly exceeds the spin polarization of the carrier density for the majority carriers. Based on this principle, we propose a semiconductor spin-polarized solar battery and substantiate our proposal using analytical arguments and numerical modeling. © 2001 American Institute of Physics.
