Abstract
A rear contact heterojunction solar cell and a fabricating method. The solar cell comprises a silicon substrate having a passivating layer and an intrinsic amorphous silicon layer. At a back side of the intrinsic amorphous silicon layer, an emitter layer and a base layer are provided. Interposed between these emitter and base layers is a separation layer comprising an electrically insulating material. This separation layer as well as the base layer and emitter layer may be generated by vapor deposition. Due to such processing, adjacent regions of the emitter layer and the separating layer and adjacent regions of the base layer and the separating layer partially laterally overlap in overlapping areas in such a way that at least a part of the separating layer is located closer to the substrate than an overlapping portion of the respective one of the emitter layer and the base layer.
