Plasma‐Enhanced Grain Growth and Non‐Radiative Recombination Mitigation in CsSnBr3 Perovskite Films for High‐Performance, Lead‐Free Photodetectors

Tin-based halide perovskites represent a highly promising and eco-friendly alternative to lead-based materials with significant potential for optoelectronic applications. However, their advancement is hampered by challenges such as poor film crystallinity and unintended self-doping. Herein, this work reports the fabrication of high-quality CsSnBr
