采用溶液衍生的NiOx膜作为柔性有机-无机混合钙钛矿太阳能电池的空穴接触。由预合成的NiOx纳米颗粒溶液旋涂得到的NiOx薄膜可以有效地提取空穴和阻挡电子，而无需任何其他后处理。在ITO玻璃衬底上的基于NiO的钙钛矿太阳能电池中，最佳功率转换效率（PCE）为16.47%，这远高于使用高温衍生的NiOx膜接触的钙钛矿太阳能电池。低温沉积工艺使NiOx薄膜适用于柔性器件。在ITO-PEN衬底上制备了NiO基柔性钙钛矿太阳能电池，初步实现了13.43%的PCE。
A solution-derived NiOx film was employed as the hole contact of a flexible organic-inorganic hybrid perovskite solar cell. The NiOx film, which was spin coated from presynthesized NiOx nanoparticles solution, can extract holes and block electrons efficiently, without any other post-treatments. An optimal power conversion efficiency (PCE) of 16.47% was demonstrated in the NiOx-based perovskite solar cell on an ITO-glass substrate, which is much higher than that of the perovskite solar cells using high temperature-derived NiOx film contacts. The low-temperature deposition process made the NiOx films suitable for flexible devices. NiOx-based flexible perovskite solar cells were fabricated on ITO-PEN substrates, and a preliminary PCE of 13.43% was achieved.
