Low stability of organic-inorganic lead halide perovskite and toxicity of lead (Pb) still remains a concern. On the other hand, the performance of non-toxic, high stable bismuth based lower dimensional perovskite and bismuth iodide (BiI3) semiconducting material has been limited due to high intrinsic carrier concentration, high exciton binding energy and poor morphology. To address this, we modulated a solvent-mediated adduct for one-step crystallization of lead-free AgBi2I7 at a lower temperature (90 °C) and to obtain remnant BiI3 by controlling the nature of the substrate and precursor concentration. This eventually resulted in remarkable enhancement in the power conversion efficiency, reaching 2.12%, and the long-term stability of AgBi2I7 solar cells towards light, heat and humidity.

有机-无机卤化铅钙钛矿的稳定性低和铅（Pb）的毒性仍然是一个令人担忧的问题。另一方面，无毒、高稳定的铋基低维钙钛矿和碘化铋（BiI 3）半导体材料的性能由于高本征载流子浓度、高激子结合能和差的形态而受到限制。为了解决这个问题，我们调制了一种溶剂介导的加合物，用于在较低温度（90 °C）下一步结晶无铅AgBi 2 I7，并通过控制基质的性质和前体浓度来获得剩余的BiI 3。这最终导致功率转换效率显著提高，达到2.12%，以及AgBi 2 I 7太阳能电池对光、热和湿度的长期稳定性。
