| 摘 要： | 对晶向为（100）的p型单晶硅片进行表面刻蚀,制作减反射绒面。本实验是在传统氢氧化钠-异丙醇混合液中分别加入不同浓度的醋酸钠溶液、硅酸钠溶液和碳酸钠溶液对单晶硅片进行刻蚀。实验发现：分别加入醋酸钠溶液、碳酸钠溶液并没有在降低表面反射率方面起到很大作用,而只有加入硅酸钠溶液降低了表面反射率,有利于形成较好的腐蚀绒面。因此...

| Abstract: | The surfaces of p-type silicon(100) wafers were texturized to reduce the surface reflectance for solar cells.We investigated different texturing processes by adding low concentration CH3COONa,Na2SiO3,Na2CO3 solutions into conventional solution of NaOH + IPA(isopropyl alcohol),respectively.We found that by adding CH3COONa and Na2CO3 solutions into mixed NaOH + IPA solution,respectively,the average reflectivity of the textured surfaces does not decrease,but by adding Na2SiO3 solution,the average reflectivity of the textured surfaces reduces and achieves a pyramid-shaped surface morphology.Therefore,a better surface texturing method was found by adding a low concentration of Na2SiO3 solution into the conventional mixed NaOH + IPA solution to obtain a low surface reflectivity for Si solar cells. |
