PTB7：PC71BM聚合物太阳电池的功率转换效率通过甲醇处理后再加一层可溶于水和醇的共轭聚电解质阴极界面层而提高到9.1%。这种效率的提高是有源层中上表面丰富的PC71BM比率和阴极界面上优先出现偶极的结果。
The power conversion efficiency of PTB7:PC71BM polymer solar cells was improved to 9.1% by treatment with methanol followed by a water- and alcohol-soluble conjugated polyelectrolyte cathode interface layer. This improvement in efficiency is a result of a combination of an enriched PC71BM ratio on the top surface in the active layer and the presence of the preferred dipole at the cathode interface.
