Abstract

Hydrogen is a renewable and environmentally friendly energy source that can replace fossil fuels by utilizing solar energy through water splitting. The hydrogen production was conducted in this research by using a tandem system of dye-sensitized solar cell–photoelectrochemical cell (DSSC–PEC) and a TiO₂ nanotube coated with BiFeO₃ (BiFeO₃/TNT) as a photoanode in the PEC. The deposition of BiFeO₃ on TNT was prepared using the following three methods: successive ionic layer adsorption and reaction (SILAR), ultrasonication-assisted SILAR, and ultrasonic– immersion method by varying the number of deposition cycles in each method. In this study, the optimum cycles for SILAR, ultrasonication-assisted SILAR, and ultrasonic–immersion methods were 15, 5, and 3, respectively. Results show that the BiFeO₃ deposited on TNT using the ultrasonic–immersion method with three cycles (BiFeO₃/TNT_UI3) demonstrates the best photoelectrochemical activity. The tandem system comprises BiFeO₃/TNT_UI3 photoanode and Pt-coated TNT dark cathode PEC cell connected to TNT/N719-based DSSC with an efficiency of 1.27%. The constructed DSSC–PEC system could produce 3.11 × 10⁻⁶ mol hydrogen in 6 h with a solar-to-hydrogen (STH) efficiency of 0.0033% in an H-type reactor filled with 0.5 M H₂SO₄ electrolyte.
