Abstract

original image

The Schottky-junction structure has been broadly applied in inorganic photovoltaic devices but has not yet been successfully applied in organic photovoltaic devices. Jinsong Huang and co-workers report on page 572 fullerene-based Schottky-junction devices that can output a much larger open-circuit voltage (∼0.95 V) than most bulk heterojunction (BHJ) organic photovoltaic devices. The efficiencies of the fullerene based Schottky-junction devices are shown to be larger than those of the state-of-the-art BHJ devices under certain conditions.
