SnO2 has been proven to be an effective electron transport layer (ETL) material for perovskite solar cells (PSCs) owing to its excellent electrical and optical properties. Here, we introduce a viable spray coating method for the preparation of SnO2 films. Then, we employ a SnO2 film prepared using the spray coating method as an ETL for PSCs. The PSC based on the spray-coated SnO2 ETL achieves a power conversion efficiency of 17.78%, which is comparable to that of PSCs based on conventional spin-coated SnO2 films. The large-area SnO2 films prepared by spray coating exhibit good repeatability for device performance. This study shows that SnO2 films prepared by spray coating can be applied as ETLs for stable and high-efficiency PSCs. Because the proposed method involves low material consumption, it enables the low-cost and large-scale production of PSCs.

用于平面钙钛矿太阳能电池的喷涂均匀性高的SnO 2电子传输层

SnO 2由于其优异的电学和光学特性,已被证明是钙钛矿太阳能电池(PSC)的有效电子传输层(ETL)材料。在这里,我们介绍了一种可行的喷涂方法来制备SnO 2薄膜。然后,我们采用通过喷涂方法制备的SnO 2膜作为PSC的ETL。基于喷涂SnO 2 ETL的PSC的功率转换效率为17.78%,与基于常规旋涂SnO 2薄膜的PSC的功率转换效率相当。通过喷涂制备的大面积SnO 2膜对于器件性能表现出良好的可重复性。这项研究表明SnO 2通过喷涂制备的薄膜可以用作ETL,用于稳定和高效的PSC。由于所提出的方法消耗的材料少,因此可以低成本,大规模生产PSC。
