Solid state p-n heterojunction sensitized photovoltaic solar cell with electron and hole conductors

A solid state p-n heterojunction comprising an electron conductor and a hole conductor; it further comprises a sensitising semiconductor, said sensitizing semiconductor being located at an interface between said electron conductor and said hole conductor. In particular, the sensitizing semiconductor is in form of quantum-dots. A solid state sensitized photovoltaic cell comprises such a layered heterojunction between two electrodes. <IMAGE>
