The conversion of solar energy into chemical energy represents an emerging frontier in renewable technologies. Photocatalysis employs catalysts activated by sunlight to drive chemical reactions, such as splitting water into hydrogen and oxygen. First, CO2 is converted to ethylene using an electrochemical reactor and solar-derived. . Solar chemical refers to a number of possible processes that harness solar energy by absorbing sunlight in a chemical reaction. Photovoltaic effect: This phenomenon occurs in solar cells, where sunlight is directly converted into electricity. . These drawbacks can be overcome by converting solar energy into chemical energy carriers, that is, Solar Fuels, that can be long-term stored and long-range transported, from the sunny and desert regions of the earth to the industrialized and populated centers, where much of the energy is needed.
