Charge extraction layers with excellent charge extraction capability are essential for achieving high photovoltaic performance in cells. In this work, a hole extraction layer (HEL) is developed by doping conductive polymer TFB into CuSCN (CuSCN:TFB(X)), which exhibits good light transparency and high affinity for the light absorber. Compared to the reference cell, the CuSCN:TFB(X) HEL-based cells show impressive enhancement owing to the increased exciton dissociation and charge extraction processes and weak recombination losses. Furthermore, matched work function, better interface contact, and appropriate domain size also contribute to the enhanced power conversion efficiency. As a consequence, the highest conversion efficiency of 15.28% is observed in a cell based on the PM6:Y6 blend film and CuSCN:TFB(1.0%) HEL, which is >16% higher than the efficiency of 13.13% in a cell with CuSCN HEL.
具有优异电荷提取能力的电荷提取层对于在电池中实现高光伏性能至关重要。在这项工作中，通过将导电聚合物TFB掺杂到CuSCN（CuSCN:TFB(X)）中来开发空穴提取层（HEL），其表现出良好的光透明度和对光吸收体的高亲和力。与参考电池相比，基于CuSCN:TFB(X) HEL的电池由于激子解离和电荷提取过程增加以及复合损失减弱而表现出令人印象深刻的增强。此外，匹配的功函数、更好的界面接触和合适的畴尺寸也有助于提高功率转换效率。因此，在基于PM6:Y6共混膜和CuSCN:TFB(1.0%) HEL的电池中观察到最高转换效率为15.28%，这比具有CuSCN HEL的电池中13.13%的效率高出>16%。
