摘　　要：为了解决含铅导电银浆引起的严重环境污染问题,通过调节玻璃料配比制备了具有不同软化点的无铅玻璃粉。制成导电银浆后,测试了其对晶体硅太阳能电池光电性能的影响。研究了银粉粒径和烧结温度对电池光电性能的影响。研究结果表明:具有低软化点(360℃)的无铅玻璃粉制备的导电银浆有更好的光电性能。微米级和纳米级共混的银粉具有优良的导电性能。选择最佳银粉粒径和烧结温度,可将晶硅太阳能电池的光电转换效率提高至18. 68%,填充因子超过76. 9%。To solve the serious environmental pollution problem caused by lead conductive silver paste,the lead-free glass frit with different softening points were synthesized by adjusting the matching of glass frit. Then,the lead-free silver paste was synthesized and its effect on the photoelectric properties of silicon solar cells was measured. The effect of particle size of silver powder and sintering temperature on the photoelectric properties of cells was studied. The results show that the conductive silver paste prepared by lead-free glass frit with lower softening point( 360 ℃) displays optimal photoelectric property. The micron/nano mixed silver powders have nice conductive property. By choicing the optimum particle size of silver powder and sintering temperature,the photovoltaic conversion efficiency and fill factor of silicon solar cell can increase to 18. 68% and 76. 9%,respectively.
