要旨

Two novel D–A–π–A organic sensitizers (WS-24 and WS-26) incorporating a benzoxadiazole (BOD) unit are synthesized for dye sensitized solar cells. An additional n-hexylthiophene unit is incorporated into WS-26 to decrease unfavourable dye aggregation, thus suppressing charge recombination and increasing the solubility. Incorporating an auxiliary acceptor of benzoxadiazole (BOD) into the π-bridge can red shift absorption bands, and sharply decrease the LUMO level. In virtue of co-sensitization, the WS-26 based DSSC device can achieve photovoltaic efficiency as high as 9.72%.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
