在聚（3-己基-噻吩）：苯基-C61-丁酸甲酯基有机光致变色材料中证明了热退火依赖的性能，其中阴离子共轭双（PFEOSO 3 Na）作为阴极界面层。当基于PFEOSO 3 Na的器件通过后退火处理时，可以实现最佳性能，表现出比对照器件高约20%的功率转换效率。原子力显微镜的研究表明，界面层的形态发生变化，在不同的设备处理过程，导致不同的电子提取效率。通过与不同界面材料的比较，进一步证明了具有PFEOSO 3 Na层的器件具有最好的电荷提取效率，这是由于其界面偶极子更强。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.4759148]
Thermal annealing dependent performance was demonstrated in poly(3-hexyl-thiophene):phenyl-C61-butyric acid methyl ester based organic photovoltaics with anionic conjugated polyelectrolyte (PFEOSO3Na) as the cathode interface layer. The best performance can be achieved when the device based PFEOSO3Na was treated by post-annealing, exhibiting about 20% higher power conversion efficiency than the control device. Atomic force microscopy studies showed that the morphology of interface layers changed under different device treatment processes, leading to various electron extraction efficiencies. Compared with different interface materials, it further demonstrated the best charge extraction efficiency in the device with PFEOSO3Na layer, due to its stronger interface dipole.
