PHOTOVOLTAIC DEVICE WITH DISCONTINUOUS INTERDIGITED HETEROJUNCTION STRUCTURE

摘要

The invention relates to a photovoltaic device (100), comprising: - a substrate based on a crystalline semiconductor material, - a first electrode comprising at least one heterojunction made on one side, called the rear face, of the substrate, this heterojunction having a layer (104) based on a doped amorphous semiconductor material, - a second electrode.The first and second electrodes are disposed on the back side of the substrate in a pattern of interdigitated combs, and the layer (104) having a plurality of portions of the doped amorphous semiconductor material separate and spaced from one another.
