Abstract

Front cover image: Practical green hydrogen production requires efficient, low-cost, nontoxic materials integrated into simple device architectures. However, achieving high solar-to-hydrogen (STH) efficiency using solely earth-abundant materials in the overall device remains a critical bottleneck. In article number CEY2706, Park et al. report a solar hydrogen production system with over 10% STH efficiency under unbiased conditions. The device combines a Se-incorporated Ni3S2 electrocatalyst with a ternary bulk heterojunction organic semiconductor composed of PM6, D18, and L8-BO. Ternary absorber enables tailored photovoltage and enhanced photocurrent by suppressing non-radiative decay pathways. Effective integration of the catalyst and light absorber offers a simple and effective route for benchmark-efficiency solar hydrogen production using earth-abundant materials.
