摘要

为了改善柔性衬底上大规模高性能平面钙钛矿太阳能电池(PSCs)的电子传输层(etl)的化学计量和电子传输，在室温下，在Ar和O}}$_{\mathbf{2}}$混合工作气体下，采用磁控溅射法制备了具有控制化学计量的ZnO薄膜作为etl。系统地研究了Ar/O}$_{\mathbf{2}}$比值对ZnO薄膜结构、电学和光学性能的影响，发现溅射ZnO etl的光电性能与PSCs的性能密切相关。

Sputtered ZnO Films as Electron Transport Layers for Efficient Planar Perovskite Solar Cells

To modify the stoichiometry and enhance electronic transportation of electron transport layers (ETLs) potentially for the large-scale high performance planar perovskite solar cells (PSCs) on the flexible substrate, ZnO films as ETLs with controlled stoichiometry are fabricated by magnetron sputtering method under a mixture working gases of Ar and O}}$_{\mathbf{2}}$ at room temperature.The impact of Ar/O}$_{\mathbf{2}}$ ratios on the structural, electrical, and optical properties of ZnO films is systematically investigated and the photovoltaic performance of the PSCs is strongly dependent on the properties of the sputtered ZnO ETLs.
