在这项工作中，我们描述了一个可升级的，两个步骤的方法来制备CH3NH3PbI3钙钛矿薄膜具有高质量和优异的均匀性在厘米级（5.0 cm×5.0 cm）。由此产生的太阳能电池的效率高达16%，小面积器件的平均效率为14.3%。值得注意的是，在5.0 cm×5.0 cm钙钛矿薄膜上制作的尺寸为1.0 cm×1.0 cm的器件显示出非常令人印象深刻的效率，高达12.6%，平均效率为10.9%（48个器件），这明显上级之前报道的厘米尺寸器件（<9.0%效率）。本方法结合了反应时间短、易于制造、优异的均匀性、良好的再现性、高器件性能和可扩展性的优点，使其在大规模光伏应用中具有潜在的能力。
In this work, we describe an up-scalable, two step approach to prepare CH3NH3PbI3perovskite films with high quality and exceptional uniformity at centimeter-scale (5.0 cm×5.0 cm). The resulting solar cells achieve efficiency up to 16% with an average efficiency of 14.3% for small-area devices. Remarkably, devices with size of 1.0 cm×1.0 cm made on the 5.0 cm×5.0 cm perovskite films display a very impressive efficiency up to 12.6% with an average efficiency of 10.9% (for 48 devices), which is significantly superior to previous reports (<9.0% efficiency) with centimeter-sized devices. The present approach combines the advantages of the short reaction time, facile fabrication, exceptional uniformity, good reproducibility, high device performance and up-scalability, enabling it the potential ability in large-scale photovoltaic applications.
