N2 - Despite remarkable progress in solvent-assisted processing of hybrid perovskite thin films, the scalable fabrication of their uniform and pin-hole free layers remains a difficult task, especially on flexible substrates. In contrast, we have demonstrated that the polyiodide-assisted conversion of Pb nanolayers into MAPbI3 results in the formation of crystalline MAPbI3 thin films on large flexible substrates already at room temperature. The exposure of stoichiometric Pb/MAI bilayers to iodine vapor leads to the formation of highly reactive polyiodide melts MAI3(L), which instantly react with the Pb nanolayers converting them into pure MAPbI3 films without byproducts or unreacted components.
