ORGANIC PHOTOVOLTAIC DEVICE HAVING A NON- CONDUCTIVE INTERLAYER

摘要

A photovoltaic device comprising a first electrode, a second electrode, an active layer between the two electrodes and an interlayer between the active layer and at least one of the electrodes. The interlayer is formed from a non-conducting material and has a thickness such that charge carriers can tunnel through. The device shows significantly improved voltage-current characteristics compared to prior art devices and is particularly suitable as a low light level detector.
