摘要/Abstract

摘要：

钙钛矿太阳能电池(PSCs)的光电转换效率(PCE)已达27%，但其工业化进程仍受限于钙钛矿吸光层的薄膜质量与稳定性问题。本研究采用丁基碘化胺(BAI)作为添加剂，通过延缓结晶速率和诱导择优取向生长，实现了对钙钛矿薄膜的晶面取向调控，使得晶粒尺寸显著增大和缺陷密度降低。得益于有机胺盐具有本征的高疏水性，优化后钙钛矿薄膜表现出更强的环境耐受性，PSCs的PCE从22.32%提升至23.46%，迟滞效应得到显著抑制。并且，柔性太阳能电池(F-PSCs)的PCE从21.51%提升至22.26%，验证了该策略在不同基底上的普适性。稳定性测试表明，BAI处理钙钛矿薄膜后PSCs的环境稳定性、热稳定性、光照稳定性以及F-PSCs的机械稳定性同步提升。本研究为钙钛矿薄膜的结晶控制和稳定性提升提供了新的解决方案，为高性能钙钛矿光伏器件的开发提供了新思路，具有显著的产业化应用价值。

Abstract:

The photoelectric conversion efficiency (PCE) of perovskite solar cells (PSCs) has reached 27%, yet their industrialization remains constrained by film quality and stability issues in perovskite layers. This study employed butylammonium iodide (BAI) as additive to regulate crystal orientation in perovskite films through retarded crystallization kinetics and induced preferred orientation growth, resulting in significantly enlarged grain sizes and reduced defect densities. Benefiting from the intrinsic high hydrophobicity of organic ammonium salts, optimized films was demonstrated enhanced environmental tolerance. Consequently, rigid devices achieved PCE improved from 22.32% to 23.46% with notably suppressed hysteresis, while flexible perovskite solar cells (F-PSCs) attained PCE improved from 21.51% to 22.26%, confirming the strategy's universality across substrates. Stability tests demonstrate that treatment of perovskite film with BAI leads to simultaneous improvements in the environmental stability, thermal stability, light stability of PSCs, as well as the mechanical stability of F-PSCs. This work provides a novel solution for crystallization control and stability enhancement in perovskite films, offering new insights for developing high-performance perovskite photovoltaics with significant industrial application potential.
