摘要:
运用AFORS-HET程序,对带有本征层的异质结(HIT)太阳能电池结构参数进行模拟分析,研究透明导电氧化物薄膜(TCO)功函数、背电场、衬底厚度以及衬底材料的选择对电池性能的影响。结果表明:p型衬底结构电池TCO功函数越小越好,而n型衬底TCO功函数越大越好。背电场对电池载流子的传输和背表面复合有较大的影响。减小衬底的厚度造成光吸收减少,短路电流降低,电池效率有一定损失。从理论上分析,n型材料更适合作为电池衬底。通过优化电池结构,获得了p型衬底电池的最高转换效率为23.38%,n型衬底电池最高转换效率26.74%。
Abstract:
The simulation of heterojunction with intrinsic thin layer(HIT)solar cells was carried out by the AFORS-HET software.The impact of device parameters on cell efficiency,such as the work function of transparent conductive oxide(TCO),back surface field(BSF),substrate thickness,and the type of substrate material was analyzed.It was found that lower TCO work function was beneficial to the solar cells with p-type substrate,while higher TCO work function benefited the solar cells with n-type substrate,and that BSF had a great influence on the carrier transport and back-surface recombination.The light absorption decreased with a reduction of substrate thickness,leading to short-circuit current reduction and the loss of cell efficiency.Theoretically,N-type substrate was more suitable for HIT solar cells.Through the optimization of cell structure,the maximum efficiency of 23.38% for p-type substrate solar cells and 26.74% for n-type substrate could be reached.
