Abstract

Surface treatment of SnO2 as an electron transport layer is essential for improving charge transport and device performance in the fabrication of perovskite solar cells. In this study, oxygen plasma with a controlled ion–radical composition ratio was used for rapid surface treatment to clean the surface of SnO2, and its performance was compared with that of the conventional UV–ozone treatment. Consequently, the plasma treatment succeeded in increasing the processing speed up to 40 times faster than that required for the conventional UV–ozone pretreatment. Furthermore, plasma pretreatment improved the photostability of solar cells.

对氧化锡层进行快速氧等离子处理以提高过氧化物太阳能电池的光稳定性

在制造过氧化物太阳能电池时，作为电子传输层的二氧化锡的表面处理对于改善电荷传输和器件性能至关重要。在这项研究中，采用了具有可控离子-自由基组成比的氧等离子体进行快速表面处理，以清洁二氧化锡表面，并将其性能与传统的紫外线-臭氧处理进行了比较。结果表明，等离子体处理成功地将处理速度提高到传统紫外线-臭氧预处理所需的 40 倍。此外，等离子体预处理还提高了太阳能电池的光稳定性。
