摘 要：Flexible perovskite solar cells(f-PSCs) have attracted tremendous attention as a promising alternative candidate for clean energy generation due to their advantages of light weight and flexibility [1]. Slot-die coating is a robust and facile deposition technique that can be applied in large-area roll-to-roll(R2 R) fabrication of thin film solar cells with the advantages of high material utilization, low cost and high throughput [2]. Herein, we demonstrate the encouraging result of f-PSCs prepared by slot-die coating under ambient environment using a two-step sequential process whereby PbI:CsI is slot-die coated first followed by a subsequent slot-die coating of organic cations containing solution. A PCE of 13.00% was obtained on a flexible substrate by the R2 R coating, which is one of the highest reported cells with all layers except for metal electrode fabricated by R2 R process under ambient condition [3].
