摘要: 以CH3NH3PbI3为代表的有机-无机杂化卤化物钙钛矿材料，具有独特优越的光电特性，例如与可见光谱基本匹配的禁带宽度、强的带边光吸收、平衡的双极性载流子输运、超长的载流子扩散距离以及合适的激子结合能等。从2009年到现在，基于钙钛矿材料构建的太阳能电池光电转化效率由最初的不足4%提升到了超过25%，结合低成本的溶液旋涂样品合成方法，使钙钛矿材料成为新型太阳能电池领域的研究热点。然而，高效率钙钛矿材料中铅元素引起的毒性，以及材料本身的不稳定性一直是阻碍太阳能电池及相关光电器件商业化的两大障碍，人们正在努力解决这些问题。在这篇综述中，详细总结了卤化物钙钛矿光伏材料的优化设计，包括结构式为AMX3的单钙钛矿，A2MM'X6的双钙钛矿，A2MX6的有序空位双钙钛矿，A'2An-1MnX3n+1的二维钙钛矿以及类钙钛矿材料（如A3M2X9）。通过材料优化设计，在一定程度上解决或改善了钙钛矿的材料稳定性和毒性问题，但光伏性能仍有待进一步优化提升。在此研究过程中，第一性原理高通量材料模拟在材料设计方面显示了预测能力，得到了与实验研究交互反馈、相互印证的结果。在综述研究进展的同时，进一步讨论了优化设计的新材料存在的问题，并展望了解决这些问题的潜在途径。Abstract: Organic-inorganic halide perovskite, as represented by CH3NH3PbI3, has been attracting increasing attention due to its advanced optoelectronic properties, such as suitable band gaps, high optical absorption, bipolar carrier conductivity, ultralong carrier diffusion length and appropriate exciton binding energy. At present, solar cells based on organic-inorganic halide perovskite have gained enormous significance and reached a power conversion efficiency exceeding 25%, which was less than 4% in 2009. In addition, combined with the low-cost solution spin-coating method for sample preparation, perovskite materials have become the focus of research in the field of novel solar cells. Researchers have been addressing the key challenges facing lead halide perovskites, including their stability and toxicity issues. In this paper, research progress on the optimal designs of halide perovskite photovoltaic materials is reviewed in detail, including single(AMX3), double(A2MM'X6), ordered-vacancy double(A2MX6), 2D(A'2An-1MnX3n+1) perovskites and perovskite-like(A3M2X9) materials. Through rational design, the material stability and toxicity of perovskites have been solved or improved to some extent but the photovoltaic performance has yet to be further optimized. In this research, the first-principles of high-throughput material simulation showed predictive ability in material design. The results of interactive feedback and mutual verification with experimental research were obtained. In addition, the problems introduced by new materials in rational designs are discussed and a powerful method for addressing these problems is proposed.
