The performance of poly(3-hexylthiophen) (P3HT) and [6, 6]phenyl C61 butyric acid methyl ester ([60]PCBM)-based inverted bulk-heterojunction (BHJ) polymer solar cells (PSCs) is enhanced by the modification of zinc oxide (ZnO)/BHJ interface with carboxylic-acid-functionalized self-assembled monolayers (SAMs). Under simulated solar illumination of AM 1.5 (100 mW/cm2), the inverted devices fabricated with SAM-modified ZnO achieved an enhanced power conversion efficiency (PCE) of 3.34% due to the increased fill factor and photocurrent density as compared to unmodified cells with PCE of 2.60%. This result provides an efficient method for interface engineering in inverted BHJ PSCs.
通过用羧酸官能化的自组装单分子层（SAMs）修饰氧化锌（ZnO）/体相异质结（BHJ）界面，基于聚（3-己基噻吩）（P3HT）和[6,6]苯基-C61丁酸甲酯（[60]PCBM）的倒置体相异质结聚合物太阳能电池（PSC）的性能得到了提高。在AM 1.5（100 mW/cm²）的模拟太阳光照下，与未修饰的电池（功率转换效率为2.60%）相比，用SAM修饰的ZnO制备的倒置器件由于填充因子和光电流密度的增加，功率转换效率（PCE）提高到了3.34%。这一结果为倒置BHJ PSC中的界面工程提供了一种有效的方法。
