Hybrid Organic–Inorganic Materials and Composites for Photoelectrochemical Water Splitting

Organic-inorganic hybrids, which synergize the merits of organic and inorganic materials, have emerged as a new class of highly versatile functional materials with tailored properties and enhanced energy conversion efficiency. In this Review, state-of-the-art results on organicinorganic hybrids, used for water splitting and generation of hydrogen as a clean and renewable fuel, are concisely summarized. Two classes of hybrid materials, i.e., organicinorganic nanocomposites and hybrid halide perovskites, are reviewed and compared for designing photoelectrochemical cells. Furthermore, promising design strategies to enhance the device performance and stability are discussed.
