Abstract:
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 a conjugated polymer which is preferably in the amorphous phase. The device shows significantly improved voltage-current characteristics compared to prior art devices and is particularly suitable as a low light level detector.
Abstract:
An electro-optic device has a first electrode, a second electrode spaced apart from the first electrode, and an active polymer layer disposed between the first electrode and the second electrode. The active polymer layer is a blend of a high band gap material with a low band gap material. An electro-optic device has an anode, a cathode spaced apart from the anode, and an active polymer layer disposed between the cathode and the anode. The cathode is constructed to provide both electron injection and hole blocking. A method of manufacturing an electro-optic device includes providing a substrate, forming an active polymer layer on the substrate, forming a layer of Cs2CO3 on the active polymer layer, and depositing a layer of metal onto the layer of Cs2CO3. The layer of Cs2CO3 on the active polymer layer provides electron injection and hole blocking for the electro-optic device.

A photovoltaic module comprises at least a first and a second photovoltaic cell, the two cells being adjacent and connected, e.g. in series, and wherein, in use, current flow through a photoactive layer of the first photovoltaic cell is in a different, e.g. substantially opposite, direction, relative to the substrate, to that through a photoactive layer of the second photovoltaic cell.

Abstract:
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.
