Analysis of the design for a-SiC:H thin films in a-SiC/c-Si heterojunction solar cells

通过应用 Ｓｃｈａｒｆｅｔｔｅｒ－Ｇｕｍｍｅｌ解法数值求解 Ｐｏｉｓｓｏｎ方程，对热平衡 ｐ＋（ａ－ＳｉＣ：Ｈ）／ｎ（ｃ－Ｓｉ）异质结太阳能电池进行计算机数值模拟分析。给出了ｐ＋（ａ－ＳｉＣ：Ｈ）膜厚及其ｐ型掺杂浓度设计，还讨论了ｐ＋（ａ－ｓｉＣ：Ｈ）／ｎ（ｃ－Ｓｉ）异质结太阳能电池稳定性。

A computer simulation model of p+(a-SiC:H)/n(c-Si) heterojuncion solar cells at thermodynamic equilibrium using a Scharfetter-Gummel solution of Poisson's equation has been developed. From results, the design of optimum thickness and p-type dopping concentration in the manufacture of p+(a-SiC:H)/n(c-Si) heterojuncion solar cells is analyzed. A design for the thick-ness and p-type dopping concentration of p+(a-SiC:H) thin films is preseated. Also, the stability of p+(a-SiC:H)/n(c-Si) heterojunction solar cells is discussed。
