Abstract
Chalcogenide perovskites have emerged as a promising candidate for light harvesting applications owing to their high stability, nontoxicity, and exceptional optical and electronic properties. Research on chalcogenide perovskites is widely centered around Zr, Hf, and Ti at the B site of the ABX3 structure. Here, we report the potential of BaTeS3 chalcogenide perovskite with Te at the B site for optoelectronic and photoelectrochemical applications. This study comprises a detailed investigation of the material's structural, optical, and electronic properties. The material shows panchromatic light absorption with an indirect bandgap of 2.32 eV. Electrochemical studies reveal that the material is an n-type semiconductor with a band position suitable for water oxidation reactions. The photoanodes fabricated using BaTeS3 exhibit a photocurrent density of 0.15 mA cm-2 at 0.62 V versus Ag/AgCl (equivalent to 1.23 V vs. reversible hydrogen electrode).
期刊介绍：
ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
