Abstract: Complex metal halides are widely explored for photovoltaic applications. However, rather poor intrinsic and environmental stability of the commonly used halide-based absorbers causes a demand for more stable photoactive materials. In this work, we report a novel family of tellurium complex polyhalides with the composition A2TeBr6I2. The crystal structure of these compounds contains [TeBr6]2− octahedra interconnected by I2 bridge-molecules via halogen bonding. They are narrow bandgap semiconductors (Eg below 1.5 eV) that show strong photoresponse. Moreover, they are easily synthesized in one step from the aqueous solution. These facts make them promising candidates for use in solar cells and photodetectors.
