Book excerpt: A guide to one of the most important aspects for affordable and highly efficient dye-sensitized solar cells Dye-sensitized solar cells have the potential to be one of the most promising photovoltaic technologies for production of renewable and clean energy. Counter Electrodes for Dye-Sensitized and Perovskite Solar Cells offers an introduction to the various types of counter electrode catalysts for dye-sensitized solar cells and perovskite solar cells, including metal and metal compounds, carbon materials, polymers, and composites. With contributions from an international panel of experts, the book contains a discussion of the design and synthesis of the catalysts, characterization and stability of the devices, as well as calculations on properties. The contributors cover a wide range of topics including information on: carbon nanotubes electrocatalysts for I-mediated dye-sensitized solar cells; Pt-loaded composite electrocatalysts for I-mediated dye-sensitized solar cells; metal contact electrodes for perovskite solar cells; and much more. The book also includes insight into the future developments in the field. This important resource Covers the various types of counter electrode catalysts and presents design strategies, synthesis methods, theoretical calculation and stability evaluation Includes information on low-cost counter electrode catalysts and commercial applications of dye-sensitized sensitized solar cells Disscuses how electrode catalysts can be applied in a range of fields, such as solar cells, fuel cells, hydrogen production, and photocatalysis Offers contributions from leading experts in the field including Anders Hagfeldt, one of the world's leading researchers in this field Written for materials scientists, solid state chemists, electrochemists, catalytic chemists, solid state physicists, and chemical industry professionals, Counter Electrodes for Dye-Sensitized and Perovskite Solar Cells is a comprehensive and authoritative guide to dye-sensitized solar cells.
