研究了小分子有机太阳能电池（SMOSCs）中由于界面电荷重组过程而导致的载流子损失。该器件由酞菁锌（ZnPc）为电子给体材料，C60为电子受体组成。用电荷提取（CE）和光致瞬态光电压（TPV）等时间分辨技术得到的结果与阻抗谱（IS）测量结果一致。值得注意的是，当比较体异质结与双层型ZnPc:C60器件时，在电荷密度分布与器件电压或载流子寿命方面观察到很大的差异。讨论了器件填充因子（FF）和开路电压（VOC）对快速载流子复合的影响。
Losses of charge carriers, due to the interfacial charge recombination processes, in small molecule organic solar cells (SMOSCs) have been investigated under operating conditions. The devices consist of zinc phthalocyanine (ZnPc) as electron donor material and C60 as electron acceptor. The results obtained by using time-resolved techniques such as charge extraction (CE) and photoinduced transient photovoltage (TPV) have been compared to the measurements carried out with impedance spectroscopy (IS) and show good agreement. Significantly, much difference is observed in either the charge density distribution versus the device voltage or the charge carriers lifetime when comparing bulk heterojunction versus bilayer-type ZnPc:C60 devices. The implications of the faster charge carrier recombination with the device fill factor (FF) and the open circuit voltage (VOC) are discussed.
