The use of all-inorganic cesium lead tribromide (CsPbBr3) in photovoltaics has gained significant attention due to its outstanding environmental stability and low cost of preparation. Printable perovskite solar cells (PSCs) based on CsPbBr3 have demonstrated a more straightforward fabrication procedure and remarkable stability, indicating great development potential. However, the preparation of the CsPbBr3 film can be challenging, as it requires depositing a high-quality PbBr2 film in a triple-layer porous scaffold and avoiding the incomplete conversion of PbBr2 in the subsequent step. Herein,...
