Abstract

Organic-inorganic halide perovskite (OIHP) materials at the heart of perovskite solar cells (PSCs) have unique crystal structures, which entail rotating organic cations inside inorganic cages, imparting them with desirable optical, electronic, and defect-tolerance properties. To exploit these properties for PSCs application, the reliable deposition of high-quality OIHP thin films over large areas is critically important. The microstructures and grain-boundary networks in the resulting polycrystalline OIHP thin films are equally important as they control the PSC performance and stability. Fundamental phenomena pertaining to synthesis, crystallization, coarsening, microstructural-evolution, and grain-boundary functionalization involved in the processing of OIHP thin films for PSCs are discussed with specific examples. In addition, the unique mechanical behavior of halide perovskites, and its implication on the reliability of PSCs, are discussed.
