Although antimony selenoiodide (SbSeI) exhibits a suitable bandgap as well as interesting physicochemical properties, it has not been applied to solar cells. Here the fabrication of SbSeI solar cells is reported for the first time using multiple spin-coating cycles of SbI solutions on SbSe thin layer, which is formed by thermal decomposition after depositing a single-source precursor solution. The performance exhibits a short-circuit current density of 14.8 mA cm, an open-circuit voltage of 473.0 mV, and a fill factor of 58.7%, yielding a power conversion efficiency (PCE) of 4.1% under standard air mass 1.5 global (AM 1.5 G, 100 mW cm). The cells retain ≈90.0% of the initial PCE even after illuminating under AM 1.5G (100 mW cm) for 2321 min. Here, a new approach is provided for combining selenide and iodide as anions, to fabricate highly efficient, highly stable, green, and low-cost solar cells.
尽管硒碘化锑（SbSeI）具有合适的带隙以及有趣的物理化学性质，但它尚未应用于太阳能电池。本文首次报道了通过在SbSe薄层上多次旋涂SbI溶液来制备SbSeI太阳能电池，该SbSe薄层是在沉积单源前驱体溶液后通过热分解形成的。其性能表现为短路电流密度为14.8 mA/cm²，开路电压为473.0 mV，填充因子为58.7%，在标准空气质量1.5全球（AM 1.5 G，100 mW/cm²）条件下功率转换效率（PCE）为4.1%。即使在AM 1.5G（100 mW/cm²）光照2321分钟后，电池仍保留了约90.0%的初始PCE。在此，提供了一种将硒化物和碘化物作为阴离子组合的新方法，以制造高效、高稳定性、绿色且低成本的太阳能电池。
