【Abstract】 In this paper, the preliminary results of studies on high efficiency silicon solar cells are briefly described. During carrying out the project of high efficiency crystalline silicon solar cell, different materials (CZ and FZ wafers with different resistivities) and different structures are tested.For improving solar cell efficiency, the technology of emitter passiviation, light diffusion (n +) and heavy diffusion (n ++ ) in different areas, back surface field, surface texture and HCL cleaning etc. are used. The best efficiency obtained up to date is 18.63%.更多还原
