• CH3NH3PbI3-based planar heterojunction PSCs were prepared with roller-coating.
• The roller coating process is systemically studied for efficient perovskite-film fabrication.
• The effect of roller coating on PSC performance was studied.
• The PSCs with the PbI2 and MAI all roller-coated showed high PCEs of up to 6.421%.
We introduce efficient planar heterojunction CH3NH3PbI3 perovskite solar cells (PSCs) fabricated with a roller coating process under ambient conditions. The perovskite films were prepared with a roller coating of lead iodide (PbI2) and a spin coating of methylammonium iodide (MAI), a successive roller coating of PbI2 and MAI, and a spin coating of PbI2 and MAI as a reference film. The PSCs with roller-coated perovskite films were systemically compared to a reference PSC with spin-coated PbI2 and MAI. In order to investigate the effect of roller coating on PSC performance, scanning electron microscopy (SEM), UV–vis absorption, and X-ray diffraction (XRD) measurements were performed. With the PbI2 roller coating, the PSCs showed excellent power conversion efficiencies (PCEs) of up to 9.52% under a standard 1-sun condition, quite comparable to the spin-coated PSCs. In addition, the PSCs with the all roller-coated PbI2 and MAI showed high PCEs of up to 6.421%, and with the aid of an additive the PCEs were further enhanced of up to 7.356%. These results support the conclusion that roller coating can be used for the facile and cost-effective manufacture of high-efficiency solution-based PSCs.
