摘　　要：研究了晶体硅太阳能电池背场铝浆对电池性能的影响,着重分析了浆料组分对硅铝合金层(P+)电性能的影响,并用光学显微镜表征了背场结构及形貌。结果表明:使用低熔点玻璃粉可以促进硅铝合金层形成;在粗细铝粉比例为2∶1时,表面电导率与表面性能最佳;同时,通过加入惰性填料能降低硅片的曲翘度,达到使用要求,相应电池光电转化率为18.09%。The effects of aluminum paste used in silicon-based solar cell on performance of the crystalline silicon solar cell were researched.Focusing on the various components of paste＇s,its effect on silicon aluminum alloyand layer（P＋） resistance was considered.Using optical microscopy,the structure and morphology of the back field was also observed.The results show that glass with low melting point could reduce the resistance of silicon aluminum alloyand,and solar cell performance is the best.The proper ratio of aluminum powder is 2∶1 for the surface conductivity and surface properties.Meanwhile,inert filler can reduce the cell bow,and meet production requirements,the photoelectric conversion of cells can reach 18.09%.
