20100243042 | HIGH-EFFICIENCY PHOTOVOLTAIC CELLS - A high efficiency photovoltaic cell includes a single crystalline or multi-crystalline silicon substrate as an absorber and a selective emitter structure on the front of the absorber. On the back of the absorber is a laminate of intrinsic amorphous hydrogenated silicon, heavily doped amorphous hydrogenated silicon, a transparent conductive oxide and back metallic contact. A method of manufacturing this high efficiency photovoltaic cell includes texturing both surfaces of the absorber, forming the various layers and annealing the photovoltaic cell. | 09-30-2010 |
