Research

      The main research interests of Sun's group is to help people to get rid of energy crisis and enviormental problems. With considerable research progress and brainstorm, our group is mainly working on artificial photosynthesis, especially on molecular solar cells & solar fuels, aiming at acclerating fundamental research to drive a conceptual transition from fossil fuels to solar energy systems. For solar cells, our group is interested in utlizing cheap molecular components such as organic dyes, pervoskite and iodione-free electrolytes. For solar fuels, our group has been trying to create man-made devices with molecular components,, including visible light driven water splitting to generate hydrogen. These include catalytic water oxidation and hydrogen production with molecular catalysts inspired by natural photosystem II and hydrogenases, interfacial studies of molecular components (such as dyes and catalysts) with nanostructured semiconductors (TiO2, NiO etc), assembly of molecular devices for total water splitting, reduction of CO2 to CO, HCOOH, MeOH, or even polycarbonates by electrochemical and photoelectrochemical methods, light convertion into heat at molecular level. The success of these projects will have a great impact on our society by offering sustainable energy systems without any costs of enviorment, and provides us with endless energy sources in the future.
