Novel Physical Vapor Deposition Approach to Hybrid Perovskites: Growth of MAPbI₃ Thin Films by RF-Magnetron Sputtering.

ABSTRACT: Solution-based methods represent the most widespread approach used to deposit hybrid organic-inorganic perovskite films for low-cost but efficient solar cells. However, solution-process techniques offer limited control over film morphology and crystallinity, and most importantly do not allow sequential film deposition to produce perovskite-perovskite heterostructures. Here the successful deposition of CH₃NH₃PbI₃ (MAPI) thin films by RF-magnetron sputtering is reported, an industry-tested method to grow large area devices with precisely controlled stoichiometry. MAPI films are grown starting from a single-target made of CH₃NH₃I (MAI) and PbI₂. Films are single-phase, with a barely detectable content of unreacted PbI₂
