Issue Date: | 2024 | Publisher: | WILEY-V C H VERLAG GMBH | Source: | Advanced functional materials, 34 (41) (Art N° 2404099) | Abstract: | Efficient manipulation of crystallization and control over defects are crucial for optimizing the performance and durability of perovskite solar cells (PSCs). In this study, a novel organic multifunctional additive, 2-(furan-3-yl)ethanamine hydrochloride (FFEACl), is introduced which plays a pivotal role in regulating the crystallization process of FAPbI3. Incorporating FFEACl into the perovskite precursor solution effectively suppresses the formation of undesirable non-perovskite phase impurities while promoting the oriented crystallization of the alpha-phase FAPbI3. Moreover, the addition of FFEACl leads to a more uniform surface potential and reduced defect density in the resulting FAPbI3 film. Consequently, the top-performing PSC exhibits an impressive power conversion efficiency (PCE) of 25.41%, along with enhanced operational stability. Notably, the fabricated PSCs maintain over 80% of their initial PCE even after 1000 h of continuous operation under one-sun illumination. The findings present a facile and effective strategy for fabricating perovskite photovoltaic devices with exceptional performance and long-term reliability. | Notes: | Yao, JX (corresponding author), North China Elect Power Univ, State Key Lab Alternate Elect Power Syst Renewable, Beijing Key Lab Energy Safety & Clean Utilizat, Beijing 102206, Peoples R China.; Zhang, H (corresponding author), Fudan Univ, Dept Mat Sci, State Key Lab Photovolta Sci & Technol, Shanghai Frontiers Sci Res Base Intelligent Optoel, Shanghai 200433, Peoples R China. hzhangioe@fudan.edu.cn; jianxiyao@ncepu.edu.cn |
