摘　　要：基于产线工艺制备了纳米绒面多晶硅太阳电池,并表征其光电转换性能。研究结果表明:相对传统微米绒坑,纳米绒面能够提升多晶硅太阳电池的短路电流,相应的光电转换效率绝对值提升大于0.4%,产线均值光电转换效率超过了19.1%。结合漫反射光谱和外量子效率测试结果,改进的光电转换的原因归结为纳米绒面能够有效地诱捕短波和长波太阳光子,增强短波和长波太阳光响应。本研究证实纳米绒面多晶硅太阳电池可利用产线工艺制备且具有较高的光电转换效率,能够实现产业化。Nano-textured multi-crystalline silicon solar cells were fabricated on industrial production line. The nano-textured multi-crystalline silicon solar cells showed an improved short-circuit current as compare to traditional multi-crystalline silicon solar cells,and resulting in an increasing amount of 0. 4% for power conversion efficiency and up to 19. 1%. The light reflectance spectra and the external quantum efficiency of the nano-textured multi-crystalline silicon solar cells were investigated.The improved power conversion efficiency was attributed to enhanced light trapping and light response by the nano-structure. The results confirm that the nano-textured multi-crystalline silicon solar cells can be produced by using the industrial production process,and has high power conversion efficiency.
