Influence of interfacial roughness on slot-die coatings for scaling-up high-performance perovskite solar cells
Abstract Slot-die coating (SDC) technology is a Varistors potential approach to mass produce large-area, high-performance perovskite solar cells (PSCs) at low cost.However, when the interface in contact with the perovskite ink has low wettability, the SDC cannot form a uniform pinhole-free perovskite film, which reduces the performance of the PSC.T
