Excellent optoelectronic properties of Pb hybrid halide perovskites made them superstars in photovoltaics. However, Pb toxicity hinders their application in consumer electronics. In this project, I studied applicability of my polyiodide-assisted/iodination method [Nat. Nanotech. 14, 57, 2019] for the fabrication of hybrid halides of transition metals. There was no significant reaction between Ti, Zr, Nb and W and MAI3 polyiodide. However, iodination of mixed Ag-Bi and Cu-Bi films resulted in Ag3BiI6, Ag2BiI5, AgBi2I7, Cu2BiI5, CuBiI4 semiconductors with direct Eg of 1.8-1.86 eV. In addition, InBiI4 films with direct Eg=1.75 eV were fabricated by spin coating from InI:BiI3 solution in DMSO. Also, a record photoconversion efficiency of 6.4% was demonstrated for optimized AgBiI4 solar cell.

铅杂化卤化物钙钛矿优异的光电性能使其成为光伏领域的超级明星。然而，铅的毒性阻碍了它们在消费电子产品中的应用。在这个项目中，我研究了我的多碘化物辅助/碘化方法在制备过渡金属杂化卤化物中的适用性[Nat. Nanotech. 14, 57, 2019]。Ti、Zr、Nb、W与MAI3聚碘化物无明显反应。然而，混合的Ag-Bi和Cu-Bi膜的碘化可以得到直接Eg为1.8 ~ 1.86 eV的Ag3BiI6、Ag2BiI5、AgBi2I7、Cu2BiI5、CuBiI4半导体。此外，在DMSO中采用自旋镀膜法制备了直接Eg=1.75 eV的InBiI4薄膜。此外，优化后的AgBiI4太阳能电池的光转换效率达到了创纪录的6.4%。
