Title: Organic spintronic devices and methods for making the same

Abstract

An organic spintronic photovoltaic device (100) having an organic electron active layer (102) functionally associated with a pair of electrodes (104, 106). The organic electron active layer (102) can include a spin active molecular radical distributed in the active layer (102) which increases spin-lattice relaxation rates within the active layer (102). The increased spin lattice relaxation rate can also influence the efficiency of OLED and charge mobility in FET devices.
