摘要
The present invention is an apparatus of mechanically stacked photovoltaic cells having two cells. The bottom cell has a layer of GaSb having regions of different conductivity forming a homojunction therein. The GaSb layer is sandwiched between a conductive substrate and a bottom passivating layer. In the bottom cell is a means for forming electrical contacts to the substrate and the incident surface of the bottom passivating layer. The top cell has a layer of GaAs having regions of different conductivity forming a homojunction therein, a top passivating layer contacting the surface of the layer of GaAs which is incident to solar radiation, and a means for forming electrical contacts to the layer of GaAs opposed to solar radiation and the incident surface of the passivating layer.
