TUNNELING-JUNCTION SOLAR CELL WITH COPPER GRID FOR CONCENTRATED PHOTOVOLTAIC APPLICATION

摘要

One embodiment of the present invention provides a photovoltaic module. The photovoltaic module includes an optical concentrator and a tunneling-junction solar cell. The tunneling-junction solar cell includes a base layer, a quantum-tunneling-barrier (QTB) layer situated above the base layer, an emitter layer, a front-side electrode, and a back-side electrode.
