Abstract

This research explores bilayer semiconductor thin films to improve photoelectrochemical water splitting, which presents a viable method for sustainable hydrogen production through solar energy. The focus is optimizing different semiconductor materials within a bilayer structure to enhance overall process efficiency. By carefully layering materials with complementary characteristics, the researchers intend to maximize light absorption over a wider spectrum, promote effective charge separation, and boost catalytic activity for splitting water. The performance of these improved bilayer thin films was assessed against single-layered versions. Results indicated a notable increase in photocurrent density, reflecting better light harvesting and charge carrier generation. Additionally, the bilayer structures showed enhanced stability, which is essential for long-term device functionality. Ultimately, the optimized bilayers demonstrated superior hydrogen evolution performance, leading to heightened hydrogen production efficiency. This strategy of employing bilayer thin films presents an encouraging pathway for developing more effective and stable photochemical water-splitting systems for sustainable hydrogen production.
