Solar Water Splitting is a fundamental resource offering detailed information on PV-electrolysis, photoelectrochemical, photothermal, photocatalyst, photobiological, and other innovative methods for the production of hydrogen gas, along with presenting the theory, design, and materials involved. This is supported by application examples, and recent developments in areas such as tandem cells, dye-sensitized photoelectrochemical cells, and perovskite cells for solar water splitting, are discussed and analyzed. This book is of interest to researchers, scientists, and advanced students across the spheres of solar energy, renewable energy, chemistry, chemical engineering, nanotechnology, and materials science, as well as engineers and industrial personnel with an interest in water splitting, solar cells, and hydrogen production. Introduces the theory, design, and materials of solar water splitting. Provides in-depth coverage of a range of processes and applications. Reviews the current progress and considers future opportunities.
