Regulating Perovskite Film Crystallization via Organic Amine Salts for Enhanced Photoelectric Conversion Efficiency and Stability
Source abstract
Abstract
The photoelectric conversion efficiency (PCE) of perovskite solar cells (PSCs) has reached 27%, yet their industrialization remains constrained by film quality and stability issues in perovskite layers.This study employed butylammonium iodide (BAI) as additive to regulate crystal orientation in perovskite films through retarded crystallization kinetics and induced preferred orientation growth, resulting in significantly enlarged grain sizes and reduced defect densities.Benefiting from the intrinsic high hydrophobicity of organic ammonium salts, optimized films was demonstrated enhanced environmental tolerance.
