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.

1. A solar cell, comprising:
a crystalline silicon base layer; a first dielectric quantum-tunneling-barrier layer in direct contact with a first side of the base layer; a first doped silicon layer having a band gap greater than a band gap of the base layer and positioned adjacent to the first dielectric quantum-tunneling-barrier layer; a first electrode electrically coupled to the first doped silicon layer; a second dielectric quantum-tunneling-barrier layer in direct contact with a second side of the base layer; a second doped silicon layer having a band gap greater than the band gap of the base layer and positioned adjacent to the second dielectric quantum-tunneling-barrier layer; and a second electrode electrically coupled to the second doped silicon layer.
