Organic photovoltaic diodes (OPVs) and organic solar cells are reviewed. Thedifferent energy and electron transfer mechanisms of solar energy harvesting as well asconversion are discussed. Pure organic nanostructures and organic/inorganic hybridnanostructures are comparatively studied for photovoltaic devices. This talk gives anoverview of materials’ aspect, charge-carrier-transport, and device physics of suchdiodes.

Furthermore, the use of solar photoenergy to reduce CO2 into hydrocarbon basedsynthetic fuels is introduced. Such artificial photosynthesis type fuel production cansimultaneously solve the energy storage and energy transport problems of photovoltaicelectricity.
