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 Focus Review, state-of-the-art results on organic-inorganic 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., organic-inorganic 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.
