摘要
采用RF-PECVD沉积技术制备P型非晶硅薄膜材料,研究硼烷浓度和加热温度对薄膜性能的影响。通过对两者优化,制备出了宽光学带隙、高电导率和致密性较好的P型非晶硅材料。作为窗口层应用到HIT太阳电池中,对其厚度进行优化,在N型单晶硅衬底上制备出了效率为14.28%的HIT太阳电池。
The influence of borane concentration and heating temperature on the properties of a-Si: H thin films deposited by RF plasma enhanced chemical vapor deposition have been studied. Under the optimum conditions p-a-Si: H thin films with wide optical bandgap, high conductivity and good microstucture were obtained. As window layers applied in HIT (heterojunction with intrinsic thin layer) solar cells, the conversion efficiency of 14.28% on N-tyoe Si wafer was achieved bv oDtimizing the thickness of P-la^er.
