一、引言 1955年Lederhandler等发现,注入电流脉冲结束后某些p-n结开路电压的衰减并不遵从简单的规律(本文(6)式),其衰减曲线呈驼峰形状(图1)。其后若干作者对这一异常现象又作了讨论。1979年Mahan等在测量硅太阳电池少子寿命的工作中给出两个对应于曲线 I. INTRODUCTION Lederhandler et al. (1955) found that the decay curve of certain open-circuit voltage of some p-n junctions did not follow the simple law (equation (6)) after the injection current pulse ended. Several authors later discussed this anomaly. In 1979, Mahan et al. Gave two measurements corresponding to the curve in the work of measuring the lifetime of silicon solar cells
