Photochemical Aspects of Solar Energy Conversion

The use of solar energy in applied photochemistry, and the future of hydrogen as an energy carrier, have also been described. 

The use of solar energy to drive chemical reactions and to synthesise active substances and intermediates has been described, as well as some key developments in the field of solar chemistry and solar chemical engineering.  

The kinetics of the elementary processes of electron transfer in the photochemical hydrogen evolution with hydrogenase using cytochrome C3 and methylviologen as carriers have been reported. The results indicate that cytochrome C3 is reduced by reduced methylviologen (MV ), and that this is followed by rapid electron transfer from C3 to hydrogenase. Molecular hydrogen has been obtained

Photogalvanic cells Molecular pigment in solution Metal (or degenerate semiconductor)-electrolyte Electrical 

Microheterogeneous redox chemistry Molecular pigments in solution Micelles-liquid- metal-liquid semiconductor-liquid Chemical 

There is now an increasing awareness of the essential similarities between different approaches to photoinduced charge-transfer, and it is significant that the period under review has produced several examples of cross-fertilization of concepts and methods between photochemical and photoelectrochemical research.
