제목 Simple All-Dip-Coating Processed Perovskite Materials for Efficient Perovskite Solar Cells
초록 Recently, organic-inorganic lead halide perovskite solar cells (PrSCs) have received intense attention from the scientific community because of their marvelous breakthrough power conversion efficiencies (PCEs) making them propitious surrogates to conventional silicon-based solar cells. Hence, an intense research has been devoted for the development of efficient fabrication methods for perovskite material layers in PrSCs. Herein, we present a facile, cost-effective, and environmentally benign approach to prepare efficient perovskite materials by simple all-dip-coating deposition. This process is in contrast to the conventional spin-casting approach with detrimental organic solvents. Notably, the perovskite materials fabricated from this process exhibited superior crystallinity, morphology, and coverage. Also, the MAPbI3 perovskite formed via Pb(NO3)2 and PbI2 undergoes additional ion-exchange reaction with unreacted Pb(NO3)2 even in the solid state, resulting in decomposition to PbI2.
