Cyclohexane is an organic compound with a chemical formula C6H12. It is a colorless liquid with a pungent odor, insoluble in water, and soluble in most organic solvents such as ethanol, ether, benzene, and acetone. Cyclohexyl fragments are a common structure in both natural and synthetic drugs. It can be used as both core structure and part of achiral side chain.
Dye-Sensitized Solar Cells (DSSCs) use photosensitizers adsorbed on the surface of nanocrystalline mesoporous titanium dioxide (TiO2) films, as well as electrolytes or solid charge-transporting materials, to convert light into electricity. They have many functions, including transparency, multicolor, and low-cost fabrication, and are deployed in glass facades, skylights, and greenhouses. Sensitizers are the key to DSSCs, which drive the operation of the entire cell by continuously absorbing light to generate a flow of electrons. Each sensitizer has its corresponding absorption spectrum distribution. To improve the matching of the absorption spectrum of the sensitizer with the solar spectrum, co-sensitization of multiple sensitizers is sometimes required to improve the conversion efficiency of solar cells.
