Sb_2S_3基体/纳米平面异质结（BnPHJ）薄膜是一种很有前途的光电转换材料。本文首次采用溶液处理聚合物/石墨烯复合膜作为Sb 2S 3/TiO 2-BnPHJ太阳能电池的空穴传输层。利用SEM、AFM、SCLC等技术研究了复合膜的形貌和空穴迁移率，并利用IMVS和EIS研究了复合膜在太阳能电池中的电荷传输和复合机制。Sb_2S_3/TiO_2-BnPHJ太阳能电池的能量转换效率为5.72%，稳定性良好。
Sb2S3-based bulk/nano planar heterojunction (BnPHJ) films are promising photoelectric conversion materials for photovoltaics. Here, a solution-processing polymer/graphene composite film is employed as hole transporting layer in Sb2S3/TiO2-BnPHJ solar cells for the first time. The morphology and hole mobility of the composite film is investigated by SEM, AFM, SCLC techniques, and IMVS and EIS are applied to study the charge transport and recombination mechanism in the solar cells. The Sb2S3/TiO2-BnPHJ solar cells delivers a power conversion efficiency of 5.72% and a good stability.
