Water-Based Perovskite Solar Cells: Precursor Chemistry, Reaction–Diffusion Kinetics, Processing Strategies, and Device Performance
Water-based perovskite solar cells (W-PSCs) provide a promising route toward reducing the use of hazardous organic solvents during perovskite fabrication. However, their development remains limited by sluggish precursor conversion, incomplete phase transformation, and poor control over film morphology. This review summ...
