The solution shearing technique was used to prepare the various layers involved in perovskite solar cells (PSCs), with a device structure of FTO/c-TiO/mp-TiO/CHNHPbI/Spiro-OMeTAD/Ag, in an area as large as 6 × 10 cm. The film morphology and thickness of each layer were optimized by varying respective shearing parameters. The fully solution-sheared PSCs exhibited a champion power conversion efficiency (PCE) of 15.89%. In comparison, the PSCs with only perovskite layer solution-sheared and other layers spin-coated showed a high PCE of 17.27%. These results demonstrate the potential of a simple, rapid, cost-effective, and scalable solution shearing process to fabricate large-area PSCs and modules.
采用溶液剪切技术制备了钙钛矿太阳能电池（PSC）中涉及的各层，器件结构为FTO/c-TiO/mp-TiO/CHNHPbI/Spiro-OMeTAD/Ag，面积达6×10平方厘米。通过改变各自的剪切参数对各层的薄膜形态和厚度进行了优化。完全通过溶液剪切制备的PSC的最佳功率转换效率（PCE）为15.89%。相比之下，仅钙钛矿层采用溶液剪切而其他层采用旋涂法制备的PSC的PCE高达17.27%。这些结果证明了一种简单、快速、经济高效且可扩展的溶液剪切工艺在制造大面积PSC和组件方面的潜力。
