Photoelectrochemical Solar Conversion Systems : Molecular and Electronic Aspects

Providing new insights into the molecular and electronic processes involved in the conversion of sunlight into chemical products, this book begins with an historical overview and a survey of recent developments in the electrochemistry of semiconductors and spectroscopic techniques. Employing a tutorial organization and balancing coverage of electrochemistry and solar energy conversion, it provides a comprehensive introduction to the science of conversion cells with emphasis in systems based on semiconductor-oxide-metal interfaces, reviews current issues and potential directions, and covers a wide range of materials from organic to inorganic cells.

It then provides a comprehensive introduction to the science of conversion cells, reviews current issues and potential directions, and covers a wide range of materials from organic to inorganic cells.

Employing a tutorial organization with balanced coverage of electrochemistry and solar energy conversion, this book covers:

• The conversion of sunlight into chemical energy and different actual conversion concepts



• Electrochemical methods for the construction and characterization of electrolyte-metal-oxide-semiconductor contacts (EMOS) in the nanodimensions, the so-called nano-emitter concept, including the electrochemical formation of metal clusters of catalytic metals and the formation of passivating layers by anodization



• The fundamentals of electrocatalysis with emphasis on the hydrogen evolution reaction and the electrochemical CO₂ reduction



• Classical and quantum mechanical theories of electron transfer reactions in metal-electrolyte interfaces and their relation with surface electronics



• The physicochemical characterization of the model system Si-SiO_x-metal-electrolyte by means of modern electrochemical, surface, and spectroscopic methods



• Improvements of conversion efficiency by means of optical effects, for example, the generation of surface plasmons by nano-dimensioned arrangements of optically active metals
