MULTILAYER PHOTOVOLTAIC OR PHOTOCONDUCTIVE DEVICES

摘要

The invention concerns optically absorptive photonic devices and in particular photovoltaic and photoconductive devices. It is particularly concerned with devices formed from multiple semiconducting layers, e.g. organic semiconducting polymers. Such a device has two central semiconductive layers which have been laminated together so as to form a mixed layer between the first and second semiconductive layers, while retaining at least some of the first and second semiconductive layers on either side of the mixed layer.
