摘　　要：微槽辊涂法与商业化卷对卷生产方式兼容,凭其成功制备出了均匀的大面积宽带隙钙钛矿薄膜.同时,在4 cm×6 cm氧化铟锡(ITO)上用微槽辊涂法结合负压蒸发工艺无退火制备出高质量SnO_(2)和Spiro-OMeTAD层.将该全辊涂器件切割为6个2 cm×2 cm器件后蒸镀金电极,在0.089 cm^(2)有效面积下获得了17.59%的功率转换效率.同时,除了起始供液区外6个器件性能接近,保证了均匀性.进一步于钙钛矿表面辊涂甲基碘化胺改善了薄膜质量,最终再结合二乙基二硫代氨基甲酸钠作为钙钛矿添加剂,将效率提升至了19.34%,这是全辊涂宽带隙钙钛矿太阳电池已报道的最高效率.The micro-groove roller coating method is compatible with roll-to-roll production,which can uniformly prepare large-area wide-band gap perovskite films.Meanwhile,excellent SnO_(2)and Spiro-OMe TAD layers were prepared by micro-groove roller coating on 4 cm×6 cm ITO substrate,where SnO_(2)layer was fabricated without any thermal annealing.Further,the 24-cm^(2)device was cut into six 2 cm×2 cm devices and then evaporated gold.Finally,all roller coated device with the highest power conversion efficiency(PCE)of 17.59%was obtained under 0.089 cm^(2)active area.Besides the initial solution supply area,the performance of the 6 devices was close,which proved the good uniformity of all roller coating large-area devices.Further roller coating of methyl iodide(MAI)on surface of perovskite improved the film quality,and finally combined with sodium diethyldithiocarbamate(NaDDTC)additive,the device efficiency was improved to 19.34%,which is the highest reported PCE of all roller coated wide-band gap perovskite solar cells so far.
