2D materials with unique opto-electronic properties have shown immense potential for application in organic photovoltaics (OPVs). In this article, we reported a facile and efficient strategy to enhance the device performance of OPVs by doping 2D material of antimonene quantum sheets (AMQSs) into PEDOT:PSS emulsion. The interfacial properties between the hole extraction layer (HEL) and PBDB-T:ITIC-based active layer were properly meliorated, achieving boosted power conversion efficiency (PCE). Results indicate that the introduced AMQSs could help suppress the recombination loss and improve charge extraction efficiency. Over 8.09% enhancement of PCE is observed compared to that of the control cell with pure PEDOT:PSS. This work provides a simple and valid strategy of HEL modification to realize high efficiency OPVs.

具有锑量子片改性空穴提取层的高效有机光伏电池

具有独特光电特性的二维材料在有机光伏 (OPV) 中显示出巨大的应用潜力。在本文中，我们报告了一种通过将锑烯量子片 (AMQS) 的二维材料掺杂到 PEDOT:PSS 乳液中来提高 OPV 器件性能的简便有效的策略。空穴提取层 (HEL) 和基于 PBDB-T:ITIC 的有源层之间的界面特性得到适当改善，从而提高了功率转换效率 (PCE)。结果表明，引入的 AMQS 有助于抑制复合损失并提高电荷提取效率。与使用纯 PEDOT:PSS 的对照细胞相比，观察到超过 8.09% 的 PCE 增强。这项工作提供了一种简单有效的 HEL 修改策略，以实现高效的 OPV。
