A highly photoconductive cathode interlayer was achieved by doping a 1 wt % light absorber, such as perylene bisimide, into a ZnO thin film, which absorbs a very small amount of light but shows highly increased conductivity of 4.50 × 10(-3) S/m under sunlight. Photovoltaic devices based on this kind of photoactive cathode interlayer exhibit significantly improved device performance, which is rather insensitive to the thickness of the cathode interlayer over a broad range. Moreover, a power conversion efficiency as high as 10.5% was obtained by incorporation of our photoconductive cathode interlayer with the PTB7-Th:PC71BM active layer, which is one of the best results for single-junction polymer solar cells.

用于高效倒置聚合物太阳能电池的光电导阴极夹层
通过将 1 wt% 的光吸收剂（如苝双酰亚胺）掺杂到 ZnO 薄膜中，实现了高光导阴极夹层，该薄膜吸收非常少量的光，但显示出 4.50 × 10(-3) S/的高度增加的电导率米在阳光下。基于这种光活性阴极夹层的光伏器件表现出显着改善的器件性能，其在很宽的范围内对阴极夹层的厚度相当不敏感。此外，通过将我们的光电导阴极夹层与 PTB7-Th:PC71BM 活性层结合，获得了高达 10.5% 的功率转换效率，这是单结聚合物太阳能电池的最佳结果之一。
