In this work, we developed WS₂ nanosheets (WS₂ NS) doped into PEDOT:PSS (PEDOT:PSS/WS₂ NS) as an efficient hole transport layer (HTL) for organic solar cells (OSCs). WS₂ NS is obtained by a simple and cost-effective liquid-phase exfoliation (LPE) method. The results show that the PEDOT:PSS:WS₂ NS anode interlayer has higher work function, reduced roughness and improved hole mobility. The devices based on PEDOT:PSS:WS₂ NS interlayer show enhanced extraction and transportation of holes and improved fill factor and short-circuit current density. Based on PM6:Y6, the power conversion efficiency (PCE) increased from 14.35% to 15.67% after WS₂ NS doping.

在这项工作中，我们开发了掺杂到 PEDOT:PSS (PEDOT:PSS/WS ₂ NS) 中的WS ₂纳米片 (WS ₂ NS)作为有机太阳能电池 (OSC) 的有效空穴传输层 (HTL)。WS ₂ NS 是通过简单且具有成本效益的液相剥离 (LPE) 方法获得的。结果表明，PEDOT:PSS:WS ₂ NS阳极中间层具有更高的功函数、降低的粗糙度和改进的空穴迁移率。基于 PEDOT:PSS:WS ₂ NS 中间层的器件显示出增强的空穴提取和传输以及改进的填充因子和短路电流密度。基于PM6:Y6，掺杂WS ₂ NS后的功率转换效率（PCE）从14.35%提高到15.67% 。
