摘要

采用宽带隙钙钛矿太阳能电池（PSCs）作为底层亚电池的串联太阳能电池（TSCs）是光伏技术的一个重要研究方向。然而，WBG钙钛矿薄膜中存在的相偏析、界面损失和结晶质量会驱动复杂的成分演变和非辐射复合，导致光电压缺陷、填充因子（FF）降解和电荷输运特性受损，从根本上限制了可实现的高功率转换效率。从这个角度来看，本文提出了高性能混合卤化物WBG钙钛矿光伏电池的系统优化框架，通过界面、溶剂、添加剂和成分工程以及先进的制造技术解决了混合卤化物WBG PSCs的关键挑战。最后，对高性能混合卤化物WBG钙钛矿光伏的未来研究方向进行了全面总结和前瞻性分析。

Challenges and Optimization Strategies for High-Performance Wide-Bandgap Perovskite Solar Cells

Tandem solar cells (TSCs) employing wide-bandgap (WBG) perovskite solar cells (PSCs) as the bottom sub-cell represent a leading research direction in photovoltaics. However, the presence of phase segregation, interfacial losses, and crystallization quality within WBG perovskite films can drive complex compositional evolution and non-radiative recombination, leading to photovoltage deficits, fill factor (FF) degradation, and impaired charge transport characteristics, which fundamentally limit the attainable high power conversion efficiency. From this perspective, this review presents a systematic optimization framework for high-performance mixed-halide WBG perovskite photovoltaics, addressing critical challenges in mixed-halide WBG PSCs through interfacial, solvent, additive, and composition engineering, along with advanced fabrication techniques. Finally, a comprehensive summary and prospective analysis of future research directions for high-performance mixed-halide WBG perovskite photovoltaics is presented.
