我们成功地展示了以ZnO和PEIE为界面层的倒置结构小分子（SM）太阳能电池，效率为7.88%。利用低成本的PEIE薄层对ZnO进行改性，降低了阴极的功函数，抑制了陷阱辅助复合，从而提高了倒置电池的效率。除了效率高外，与传统电池相比，倒置SM太阳能电池在空气中相对稳定。
We successfully demonstrate inverted structure small-molecule (SM) solar cells with an efficiency of 7.88% using ZnO and PEIE as an interfacial layer. Modification of ZnO with a cost-effective PEIE thin layer increases the efficiency of the inverted cell as a result of reducing the work function of the cathode and suppressing the trap-assisted recombination. In addition to the high efficiency, the inverted SM solar cells are relatively stable in air compared to conventional cells.
