Lead-free perovskite KCsSnI_1.7Cl_1.3 material exhibiting superior photocatalytic antimicrobial activity.

ABSTRACT: The development of environmentally friendly and highly efficient materials is critical for next-generation antibacterial and optoelectronic applications. In this study, we present the successful synthesis of a novel lead-free perovskite, KCsSnI_1.7Cl_1.3, via a rapid and scalable chemical bath deposition method at 150 °C for just 5 min. The resulting film features well-defined orthorhombic, pyramid-like crystals with uniform grain sizes (800-1000 nm) and a compact, pinhole-free morphology. Remarkably, the material exhibits strong optical absorption up to 800 nm, positioning it as a promising candidate for hot electron generation and light-driven applications. KCsSnI_1.7Cl_1.3 also demonstrated outstanding antibacterial performance, showing broad-spec
