一种钙钛矿太阳能电池用Cs3BixIn2-xI9光活性层的制备方法
摘要：
一种钙钛矿太阳能电池用Cs3BixIn2‑xI9光活性层的制备方法，属于纳米材料和太阳能电池技术领域。Cs3BixIn2‑xI9光活性层制备方法：Cs3BixIn2‑xI9光活性层通过一步溶液旋涂法制备，将CsI、BiI3及InI3粉末分散在DMF/DMSO混合溶液中形成前驱体溶液，旋涂在玻璃基底上，经过加热退火形成钙钛矿薄膜；以Cs3BixIn2‑xI9为钙钛矿层太阳能电池的制备：配置空穴传输层溶液(70㎎spiro‑MeoTAD，17μl锂盐，28μl4‑叔丁基吡啶，1ml氯苯)，将配置好的溶液旋涂在Cs3BixIn2‑xI9钙钛矿表面，静置12小时后，将样品放在蒸银真空镀膜仪中，蒸镀一层60nm的银电极；蒸镀完成后，用丁内酯将光阳极擦出即可获得钙钛矿太阳能电池。优点：本发明的钙钛矿太阳能电池具有极强的稳定性，成本低廉，制备工艺简单，环境友好，能进行大规模生产。
摘要（英）：

The invention discloses a preparation method of a Cs3BixIn2-xI9 photoactive layer for a perovskite solar cell, belonging to the technical field of nano materials and solar cells. The preparation method of the Cs3BixIn2-xI9 photoactive layer: preparing a Cs3BixIn2-xI9 photoactive layer by an one-step solution spin coating method, and dispersing CsI, BiI3 and InI3 powder in DMF/DMSO mixed solution to form a precursor solution, which is spin-coated on a glass substrate. After heating annealing to form a perovskite film; preparaing a perovskite solar cell with Cs3BixIn2-xI9: a hole transport layersolution (70 mg spiro-MeoTAD, 17 [mu]l lithium salt, 28 [mu]l 4-t-butylpyridine, 1 ml chlorobenzene), performing spin-coating the surface of Cs3BixIn2-xI9 perovskite with the prepared solution. Afterstanding for 12 hours,placing the sample in a steamed silver vacuum coating machine, and evpaotring a 60 nm silver electrode; after evaporation, wiping out photoanode to obtain a perovskite solar cell by the lactone. The method has Advantages of extremely strong stability, low cost, simple preparation process, environmental friendliness, and can be mass-produced.
