摘　　要：介绍了光诱导镀(light-induced plating,LIP)应用于太阳电池的背景、发展历史及其工作原理。论述了光诱导镀技术对太阳电池性能的影响,并重点探讨了光诱导镀技术对太阳电池前表面电极接触性能的改善效果。同时,还讨论了光诱导镀技术应用于铝背表面场(Al-BSF)和激光烧制接触(laser fired contact,LFC)两种高效太阳电池上所取得的成果。当接触电阻成为串联电阻中的主要成分时,光诱导镀能够降低接触电阻、提高填充因子,从而提高电池的效率。光诱导镀特别适合于改善串联电阻较大的电池,利用光诱导镀也可以重新优化电池的烧结条件,得到更高的电池效率。Application background, development history and basic principles of the light-induced plating （LIP） technology for solar cells are reviewed. The impact of LIP technology on the performance of solar cells is discussed, with emphasis on the improvement effect of the front-surface electrode contact performance for solar cells. In addition, the results achieved by applying LIP technology to two kinds of high-efficiency solar cells, i.e. Al-BSF and laser fired contact （LFC） solar cells. When the contact resistance becomes the chief component in the series resistance, the LIP technology may reduce the series resistance and enhance the fill factor, and eventually improve the cell efficiency. LIP technology is especially proper for cells with high series resistance. Besides that, annealing conditions can be optimized with the help of LIP technology for higher efficiency.
