“…The band bending then, is given by VB = Electrode potential -Vfb (3) At equilibrium in the dark, the electrode potential (the position of EF), is equivalent to the potential of the redox couple, Vredox (the position of Er dox on the potential scale is Vred x), in the electrolyte. The extent of band bending in this case, which is approximate ?y the difference between the redox couple potential and the flat -band potential, VB = Vredox -Vfb (4) represents the barrier height that is the maximum driving force for separation of electronhole pairs.…”

“…Photochemistry is primarily useful for direct fuel production and can also be used to produce electric current through photogalvanic cells. Photochemical reactions can also be used for the production of heat in various ways, but photochemical methods are primarily suited for fuel production (Lichtin, 1974;Archer, 1975).…”

Abstract-Photosynthesis, both natural and as a model process, is examined as a possible annually renewable resource for both material and energy. The conversion of carbohydrate from cane, beets and other sources through fermentation alcohol to hydrocarbon may again become economic in the light of improved fermentation technology. It may also be possible to produce material by direct fcrmentation of relatively labile carbohydrates in seaweed. Even the direct photosynthetic production of hydrocarbon from known sources (Heoea, etc.), or newly bred ones, seems possible in view of the large number of species and the new techniques of plant cell cloning which have already been successful on sugar cane.Finally, more distantly, synthetic systems constructed on the basis of our growing knowledge of the photosynthetic processes may produce fuel, fertilizer and power. Thus, from our current knowledge of the natural quantum conversion process in green plants we can envisage several photoelectron transfer processes. In a first one the excited sensitizer (chlorophyll) transfers its electron to an acceptor molecule such as an iron-sulfur complex which, in turn, could either reduce a carbon compound or pass that electron into a hydrogen-generating system leading to the evolution of molecular hydrogen. The remaining cation radical sensitizer would have to be neutralized through a chain of electron transfers which begins at another sensitized reaction (presumably by another kind of chlorophyll) through a quinone and other electron carriers. Finally, the last cation radical near the oxidation level of oxygen could be neutralized by electron transfer, ultimately from a water molecule (hydroxide or bicarbonate ion) involving a manganese catalyst.Some steps in this sequence of transfers have already been demonstrated in synthetic systems. However, the actual physical construction of such a complete system is a much more complex task.
