Vacuum evaporation is promising for the high-throughput fabrication of perovskite solar cells (PSCs) because its solvent-free characteristic, precise control film thickness, and compatibility with large-scale production. Nevertheless, power conversion efficiency (PCE) PSCs fabricated by vacuum lags behind that solution-processed PSCs. Here, we report a Cl-containing alloy–mediated sequential approach to fabricate films. The presence Cl in alloy facilitates organic ammonium halide diffusion...
Abstract Vacuum evaporation is promising for the scalable fabrication of perovskite solar cells (PSCs). Nevertheless, poor thermal conductivity metal halide powder leads to unfavorable temperature inhomogeneity, which destabilizes rate, posing a major challenge reproducible deposition films, particularly by coevaporation. Herein, molten salt strategy reported sequentially vacuum PSCs. The increases halides and greatly homogenizes temperature, stabilizes rate composition resulting films. PSCs...
