| description | Chalcogenide perovskites have emerged as potential semiconductor materials for optoelectronic devices due to their superior visible light absorption and high thermal and chemical stability. Here, we report BaZrS3 chalcogenide perovskites-based photoelectrode for photoelectrochemical water splitting (PEC). Experimental findings reveal that BaZrS3 exhibits excellent stability in harsh pH conditions (pH 3–13) and shows panchromatic absorption with a band gap of 1.77 eV. Temperature-dependent impedance and Raman spectroscopy unveil the presence of polarons and suggest the possibility of polaron-mediated conduction in this material. Under 1 Sun illumination, the PEC device attains a maximum photocurrent density of 0.36 mA/cm2 at 0.323 V vs Ag/AgCl at pH 12 (equivalent to 0 V vs RHE), maintaining stability for 30 min. Notably, the photoanode exhibits remarkable stability before and after the photoelectrochemical reaction. BaZrS3 photoanode displays high surface charge separation efficiency, promoting the surface oxidation reaction. |
