ABSTRACT Lead‐free tin halide perovskites, particularly Cs 2 SnBr 6 , are gaining significant attention for their potential in optoelectronic applications. In this study, we investigate the material's electrical and vibrational properties under varying illumination conditions, providing novel insights into impact of light on its conduction mechanisms. was synthesized via liquid‐phase solid‐state reactions, report comprehensive analyses impedance, AC conductivity, dielectric over a wide frequency range. Notably, our results reveal that light‐induced photogenerated charge carriers enhance which is well explained by overlapping large‐polaron tunneling (OLPT) model, while darkness, material follows correlated barrier hopping (CBH) model. Moreover, Raman spectroscopy highlights structural changes, including slight shortening Sn–Br bond distances illumination, influences frequencies intensities. These findings emphasize crucial role tuning responses thus demonstrating considerable promise future applications, such as solar cells photodetectors.

ABSTRACT Lead‐free double perovskites, such as Cs 2 AgInCl 6 , represent a promising class of materials for optoelectronic applications due to their favorable properties and environmental sustainability. This work focuses on the synthesis comprehensive characterization employing range techniques including X‐ray diffraction (XRD) structural verification, thermogravimetric analysis (TGA) assess thermal stability, UV–visible absorption measurements determine optical bandgap energy 3.32 eV. Additionally, we explore photoluminescence (PL) decay elucidate luminescent compound. Complex impedance are performed under both blue red light investigate electrical behavior, revealing two distinct conduction mechanisms: overlapping large–polaron tunneling (OLPT) nonoverlapping small–polaron (NSPT). We analyze implications our findings current–voltage (I–V) behavior trap density, further supported by Raman spectroscopy illumination conditions. The combined insights from characterizations highlight potential in applications, paving way its use advanced devices.
