سلول های خورشیدی پروسکیت هم سطح پوشش دار شده قالب تحت فشار با جوشیدگی و حرارت دهی رسوب یک مرحله ای

برای این منظور، سلول‌های خورشیدی پروسکیت بر پایه CH3NH3PbI3 با استفاده از پوشش دهی قالب تحت فشار و روش مقیاس پذیر ساخته شدند. پوشش دهی قالب تحت فشار تمایل به تولید لایه‌های پروسکیت با پوشش بسیار کم‌تر با پوشش بلورهای بیش از حد نسبت به پوشش اسپین دارد.

Highlights•Scalable and roll-to-roll compatible deposition process is developed to produce planar perovskite solarcells.•The highest efficiency from single-step slot die coated perovskite solar cells is achieved.•Synergy effect of gas blowing and heating on morphology of slot die coated films is found.AbstractCH3NH3PbI3-based planar perovskite solar cells were fabricated by slot-die coating, a scalable method. Slot-die coating tends to produce perovskite layers with much lower coverage with overgrown crystals than spin coating, which does not include a self-drying mechanism in the process. To mimic the self-drying behavior inherent in spin coating, the present study introduces a blowing step in the slot-die coating method, which significantly improved coverage of the prepared slot-die coated perovskite films. The slot-die-coated device with blowing showed a moderate power conversion efficiency (PCE) of 8.8%. The morphology of the slot-die-coated perovskite film is further improved by o
