Abstract

Abstract

The electron transport layer(ETL) plays a crucial role in carrier extraction and transportation in perovskite solar cells. Tin(Ⅳ) oxide is widely used as ETL-material in planar perovskite solar cells due to its excellent properties. However, current processes for tin oxide film preparation can hardly meet industrial requirements, such as large-scale and automatic fabrication. Therefore, developing a new fabrication method suitable for industrialization is in urgent demanded. To solve this problem, a high-quality tin oxide film was successfully created using the spray coating method. Experimental results show that the performance of the perovskite solar cells is highly dependent on the thickness of the spray-coated tin oxide film. By optimizing film thickness, power conversion efficiency(PCE) can be improved to 15.72%. The film exhibits a coffee ring phenomenon, which increases the series resistance and limits the PCE. That can be solved by further decreasing the size of the droplets. This paper demonstrates a new method for the fabrication of high-quality, highly adaptable tin oxide films for the industrialization of perovskite solar cells.
