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].

Organic solar cells(OSCs)have been developed rapidly in past years,due to the fast evolution of wide-bandgap copoly-mer donors and low-bandgap non-fullerene acceptors[1−9].At present,the highest power conversion efficiencies(PCEs)for single-junction OSCs and tandem OSCs exceed 19%and 20%,respectively[10,11].These OSCs are typically fabricated by us-ing low-boiling-point solvent chloroform(CF)with an effect-ive area<0.1 cm^(2).The doctor-blading deposition is the most advantageous technique to fabricate OSCs with low-boiling-point solvent for upscaling lab cells to industrial-scale mod-ules[12],exhibiting simple operation,low cost,and high materi-al utilization[13−15].Herein,a typical OSC material system PM6:Y6(Fig.1(a))was used to fabricate OSCs modules via doc-tor-blading deposition in ambient condition,and the influ-ence of the ambient temperature and substrate temperature on the film quality was investigated.
