An organic spintronic photovoltaic device having an organic electron active layer functionally associated with a pair of electrodes. The organic electron active layer can include a spin active molecular radical distributed in the active layer which increases spin-lattice relaxation rates within the active layer. The increased spin lattice relaxation rate can also influence the efficiency of OLED and charge mobility in FET device.
