Abstract In this work, electron transport layers (ETLs) with high charge transfer ability were prepared by doping ZnO nanoparticles with different concentrations of cadmium(Cd). The inverted polymer solar cell based on PTB7-Th: PC71BM as active layer and various concentrations Cd-doped ZnO (CZO) as ETLs were fabricated. The PCE of the device with optimized Cd content in the ZnO film was about 14.7% larger than that of the pure ZnO-based cells. The cadmium-doped ZnO(CZO) is a good candidate to be used as a high-quality transparent electrode in solar cell applications.

可溶液加工的 Cd 掺杂 ZnO 纳米粒子作为电子传输层，通过提高导电性和透光率实现高性能聚合物太阳能电池

摘要 在这项工作中，通过用不同浓度的镉 (Cd) 掺杂 ZnO 纳米粒子制备了具有高电荷转移能力的电子传输层 (ETL)。以PTB7-Th:PC71BM为活性层，以不同浓度的Cd掺杂ZnO（CZO）为ETL，制备了倒置聚合物太阳能电池。ZnO 薄膜中具有优化 Cd 含量的器件的 PCE 比纯 ZnO 基电池的 PCE 大约 14.7%。镉掺杂的 ZnO(CZO) 是太阳能电池应用中用作高质量透明电极的良好候选材料。
