我们在环境条件下利用喷涂依次存款致密TiO 2、中孔TiO 2、CH 3 NH3 PbI（3−x）Clx钙钛矿和掺杂螺-OMeI层，从而形成中孔标准结构钙钛矿太阳能电池（PSC）。所产生的器件具有9.2%的平均功率转换效率（PCE）和10.2%的峰值PCE;与通过旋转铸造制造的具有11.4%的平均效率的对照器件相比，该值是有利的。我们表明，我们的过程可以用来创建具有1.5平方厘米的有效面积具有独立验证的效率为6.6%的设备。这项工作展示了喷涂的多功能性以及其作为制造低成本，大面积，高效钙钛矿设备的方法的潜力。
We utilise spray-coating under ambient conditions to sequentially deposit compact-TiO2, mesoporous-TiO2, CH3NH3PbI(3−x)Clx perovskite and doped spiro-OMeTAD layers, creating a mesoporous standard architecture perovskite solar cell (PSC). The devices created had an average power conversion efficiency (PCE) of 9.2% and a peak PCE of 10.2%; values that compare favourably with control-devices fabricated by spin-casting that had an average efficiency of 11.4%. We show that our process can be used to create devices having an active-area of 1.5 cm2 having an independently verified efficiency of 6.6%. This work demonstrates the versatility of spray-coating as well as its potential as a method of manufacturing low-cost, large-area, efficient perovskite devices.
