摘　　要：在现有大规模产业化生产线NaOH+H2O+乙醇制绒体系的基础上,研究了两性表面活性剂替代乙醇的可行性,测试了两性表面活性剂在不同浓度条件下制备得到绒面的表面反射率和SEM形貌图。研究结果表明,两性表面活性剂在单晶硅太阳电池制绒中具有重要的作用,表面活性剂的制绒效果要显著优于以乙醇为添加剂的腐蚀溶液,表面活性剂在制绒液中浓度为0.0005%时得到最优实验结果。The feasibility of amphoteric surfactant instead of ethanol based on the NaOH＋H2O＋Ethanol texture system of silicon solar cell mass production was analyzed. The surface reflectance and SEM images of textures prepared in different concentrations were tested. The results showed that amphoteric surfactants played a key role in texturing and the texturing quality of amphoteric surfactant had an obvious improvement by comparing with ethanol surfactant, and the optimized results of amphoteric surfactant at the concentration of 0.0005% would be achieved.
