UNIST Researchers Develop Organic Photoelectrode with Platinum Nanoparticles Achieving Record Hydrogen Production Efficiency
A team from the Ulsan National Institute of Science and Technology (UNIST) has developed an organic photoelectrode that achieves 8.88% efficiency in solar hydrogen production. This advancement utilizes a specialized polymer coating to enhance the stability of platinum catalysts on organic semiconductors, addressing historical challenges related to hydrophobic surfaces.
The photoelectrode demonstrated a photocurrent density of 17.7 mA/cm² and maintained performance over extended periods. The process allows for liquid-phase manufacturing, potentially reducing costs and enabling large-scale production. This innovation could facilitate the installation of solar hydrogen systems in resource-rich regions and be integrated into decentralized reactors or industrial applications.
