英文摘要	High quality and uniform dense perovskite films are essential to exciton dissociation and charge transportation in perovskite solar cells (PSCs). Although MA(1-x)FA(x)PbI(3) planar films can be fabricated by a solution process with chlorobenzene anti-solvent, the fabrication still suffers from problems such as environmental pollution, high cost and low reproducibility. In this work, we present a HI and MACl assisted 2D-3D conversion mechanism (HI-MACl ACM), defined as an anti-solvent-free method, to fabricate pure phase MA(1-x)FA(x)PbI(3) and enhance the quality of perovskite films. The intermediate 2D HMA(1-x)FA(x)PbI(3)Cl derived from HI-MACl ACM eventually transforms to 3D MA(1-x)FA(x)PbI(3) perovskite. This 2D structure also has an impact on retarding nucleation. The obtained films were composed of highly crystallized and large grains (over 1000 nm), which minimized grain boundaries and trap sites, giving a power conversion efficiency above 18.86% in PSCs.
