简介:小分子有铟听氧化物(ITO)的结构的器官的太阳能电池(振荡)/molybdenum三氧化物(MoO3)(5nm)/rubrene(nm)/fullerene(C70)(ynm)/2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline(BCP)(6nm)/aluminum(艾尔)(150nm)被制作。为设备的活跃的层的厚度在细节被调查。结果证明rubrene层和C70层的最佳厚度分别地是30nm和25nm。设备的降级也被调查。,结果显示开电路的电压(Voc)不变化电线走火电流密度(Jsc),用时间连续地填满因素(FF)和功率变换效率(PCE)减少。降级能在周围的扩散并且渗透到活跃材料并且在房间与C70反应被归因于氧,它能导致界面的系列电阻的增加。
