The Korea Institute of Machinery and Materials (KIMM) has made a significant advancement in green hydrogen production by developing a technology that efficiently generates high photocurrent under natural sunlight. This breakthrough involves simplifying complex processes, particularly in the fabrication of BiVO4 photoelectrodes, which are crucial for solar water-splitting systems. By optimizing the precursor solution, the research team managed to boost productivity by almost 6 times compared to traditional methods, enabling the creation of large-area electrode systems. This development, when combined with Si solar cells, allowed for stable hydrogen production solely powered by natural sunlight, eliminating the need for external power sources. Dr. Jihye Lee, the leading researcher, emphasized the impact of this breakthrough on accelerating the transition to sustainable energy and facilitating the commercialization of green hydrogen. The team's achievement has led to the filing of patent applications, highlighting the potential for further innovation and adoption of this technology in the renewable energy sector.
