Abstract Perovskite solar cells are based on organolead halide compounds which are used as highly efficient solar cell absorber materials. However, their lead component is a high human health concern, toxic, and causes strong damages when disperse in the environment. In the present paper, silver iodobismuthate compounds are investigated as lead-free semiconductors in replacement of organolead halide in perovskite solar cells. We describe the design of thin films of AgBixI3x + 1 for x composition ranging between 1 and 2.25. The preparation is optimized to get well-crystallized well-covering layers. The prepared compounds are semiconductors, absorbing light below 700 nm. Compounds for x

探索用于无铅钙钛矿太阳能电池的 AgBi x I 3x+1 半导体薄膜

摘要 钙钛矿太阳能电池基于有机卤化铅化合物，用作高效太阳能电池吸收材料。然而，它们的铅成分对人类健康有很高的关注，有毒，在环境中扩散时会造成强烈的破坏。在本论文中，研究了碘铋酸银化合物作为无铅半导体替代钙钛矿太阳能电池中的有机卤化铅。我们描述了 AgBixI3x + 1 薄膜的设计，x 组成范围在 1 到 2.25 之间。优化制备以获得结晶良好的覆盖层。制备的化合物是半导体，吸收低于 700 nm 的光。x 的化合物
