Abstract
In one aspect, single-junction organic photovoltaic devices are provided exhibiting high Voc values while employing single-junction architecture. A single-junction photovoltaic device described herein comprises an anode, a cathode and an active layer residing between the anode and cathode, the active layer comprising an organic electron donor and an organic electron acceptor, wherein the photovoltaic device generates a Voc of at least 1.4 V. Uniquely, high Voc photovoltaic devices described herein can be transparent to the majority of visible and/or infrared spectral irradiation in some embodiments.
