摘　　要：一、前言 对薄膜CdS/Cu_2S光伏器件稳定性的研究表明,温度对电池寿命的影响是不可忽视的因素。J·Meikin指出,在40℃下对CdS/Cu_2S电池加热5000小时,Ⅰ_(sc)仅下降1％;对于包封电池,K.Boer得出,在60℃下加热两年电池性能没有发生衰变的结论。 我们通过对CdS/Cu_2S太阳电池的加热寿命试验,寻求器件寿命与温度间的关系。In this paper, the lifetime of thin film photovoltaic GdS/Cu2S solar cells is calculated using Arrhenius equations of lifetime-temperature relations for semiconductor device. The results show that the operation life times of thin film CdS/Cu2S solar cell are 2 × 104 hours under temperature 50℃.Using light-spots scanning technology, the decay surface current distributions of CdS /Cu2S device are obtained on a scanning instrument. The place, form and area of the defect in thin film CdS/Cu2S solarcell are also observed.
