摘要

太阳能电池是一种清洁的可再生能源，有助于实现可持续发展目标7；可负担的清洁能源。钙钛矿太阳能电池因其25%以上的高功率转换效率而引起了研究人员的注意。作为钙钛矿活性层的材料的一个例子是FASnI3。为了提高带隙的可调性和稳定性，可以在带隙中掺杂卤化物材料。本研究首先合成了FASnI2Br，然后用XRD进行了结构表征，用UV-vis进行了光学表征。所制器件的FF为50.44%，PCE为3.57%，Jsc为12.46 mA/cm2， Voc为0.44 V， MPP为3.57 mW/cm2。这是钙钛矿太阳能电池活性材料的一个很好的指示。

Synthesis and characterization for structural and optical properties of FASnI2Br for perovskite solar cell applications

Solar cells being a clean and renewable energy source, help achieve sustainable development goal number 7; Affordable and clean energy. Perovskite solar cells have attracted the attention of researchers due to their exemplary high-power conversion efficiencies of above 25 %. An example of a material that has been used as a perovskite active layer is FASnI₃.For tunability of the band gap and enhancing stability, this can be doped with halide materials. In this study, FASnI₂Br was synthesized, followed by structural characterization using XRD and optical characterization using UV–vis. From the fabricated devices, FF of 50.44 %, PCE of 3.57 %, Jsc of 12.46 mA/cm², Voc of 0.44 V and MPP of 3.57 mW/cm² were obtained. This was a good indication for an active material for perovskite solar cells.
