摘　　要：应用TMAH和NaOH分别对硅基太阳能电池进行背抛光。研究表明,TMAH抛光效果优于NaOH。其最佳抛光温度为67℃,最佳异丙醇浓度为20mL/L,催化剂吡嗪浓度为2g/L。随着抛光时间的增加,电池的转换效率先增加后减少,最佳抛光时间为90s,多晶硅电池转换效率提高了0.48%。The back-side polishing process based on TMAH and NaOH was studied and compared.The experiment results show that the polishing effect of TMAH polishing was better than NaOH.The best TMAH polishing temperature was 67℃.The best isopropanol concentration was 20mL/L,the concentration of 2g/L catalyst pyrazine.With the polishing time increasing,the solar cell conversion efficiency increases firstly and then decreased.The best polishing time was 90s;the conversion efficiency of the poly solar cell increases by 0.48%.
