摘　　要：为了研究银铜双金属一步法黑硅技术,对采用该方法处理后的黑硅多晶硅硅片进行测试,并以产线工艺为基础制备黑硅多晶硅太阳电池;使用测试仪等研究了黑硅多晶硅硅片的显微组织、界面结构、宏观形貌,以及黑硅多晶硅太阳电池的量子响应、电性能参数与光衰性能。结果表明,黑硅多晶硅太阳电池的电性能有显著提升,尤其是短路电流提升了221 mA,这主要是由于黑硅多晶硅太阳电池的短波段量子响应有显著改善;同时,黑硅多晶硅太阳电池的光衰特性优于常规多晶硅太阳电池。One Ag-Cu bimetal one-step process technique was carried out on industrial production.Black silicon multi-crystalline silicon solar cell was prepared.The parameters such as microstructure,interfacial structure,surface structure,quantum response,electrical characteristics and LID were investigated by tests.The results show that the electric properties of black silicon solar cells are improved.The short circuit current has an increase of 221 mA,which is mainly due to the enhancement of blue spectral response.Meanwhile,the LID for the black silicon multi-crystalline solar cells is also better than normal mutli-crystalline silicon solar cells.
