摘要

Sb2(S, Se)3太阳能电池具有成本低、无毒、稳定性高等优点,具有广阔的应用前景。然而,传统器件普遍采用贵金属作为背电极,这不仅增加了器件成本,而且限制了器件的稳定性。本文采用碳材料代替Sb2(S, Se)3太阳能电池中的贵金属。此外,为了生长高质量的Sb2(S, Se)3薄膜,开发了两步水热法。基于上述薄膜的碳基Sb2(S, Se)3太阳能电池的功率转换效率(PCE)为2.76%。在Sb2(S, Se)3膜/碳界面处插入稳定的P3HT层后,空穴萃取率增强,PCE提高到4.15%。这项工作为生产具有成本效益和稳定材料的新兴太阳能电池提供了一条有前途的途径。

Carbon-Based Sb2(S, Se)3 Solar Cells
Sb2(S, Se)3 solar cells have shown great promise due to the advantages of low cost, non-toxic and high stability. However, traditional devices commonly use noble metal as the back electrode, which not only increases device cost but also limits device stability. Herein, carbon materials are used to replace the noble metals in Sb2(S, Se)3 solar cells. In addition, to grow high-quality Sb2(S, Se)3 films, a two-step hydrothermal method was developed. The carbon-based Sb2(S, Se)3 solar cells based on the above film achieved a power conversion efficiency (PCE) of 2.76%. After inserting a stable P3HT layer at the Sb2(S, Se)3 film/carbon interface, hole extraction was enhanced and the PCE was promoted to 4.15%. This work brings out a promising route to produce emerging solar cells with cost-effective and stable materials.
