A photoelectrochemical (PEC) system combines the harvesting of solar energy with the electrolysis of water [2]. Section two will discuss our results looking at the catalysis of hydrogen production on semiconductor electrodes. The energy efficiency of electrolysis can. . The organization of photoresponsive molecular systems and nano-materials on semiconductor surface holds great potential in the building of solar energy conversion devices where efficient energy conversion results from the optimized cooperation of several subsystems (semiconductor, dye sensitizers. . Semiconductor/liquid junctions provide the most efficient wet chemical method presently known for converting solar energy. These devices have been studied for over forty. . The selective conversion of renewable biomass to value-added chemicals/fuels via environment-friendly photoelectrochemical (PEC) technology has enormous development potential for solving the increasingly serious problems associated with the energy crisis and environmental pollution.
