  • Composite electrode of TiO2 particles with three kinds of crystal phases for significantly improved performance of dye-sensitized solar cells

    摘要： A novel composite electrode of TiO2 particles with three kinds of crystal phases is fabricated for improving the dye-sensitized solar cell's performance. The photoelectric conversion efficiency of solar cell with the content of 30 wt% brookite nanocubes and 70 wt% P25 could reach 7.40%. It is obvious that brookite nanocubes are advantageous in terms of reduced charge recombination and higher voltage. On the other hand, P25 gives advantages of high surface area for dye loading and higher charge collection efficiency. This work shows a new photoelectrode design for enhanced energy conversion of DSSCs.

  • [IEEE 2019 18th International Conference on Optical Communications and Networks (ICOCN) - Huangshan, China (2019.8.5-2019.8.8)] 2019 18th International Conference on Optical Communications and Networks (ICOCN) - Composite transparent conductive electrode for printed electronic devices

    摘要： The new transparent conductive electrode consists of three materials: silver nanowires (AgNWs), zinc oxide nanoparticles (ZnO), and reduced graphene oxide (rGO). We prepared a silver nanowire electrode by spin coating a silver nanowire solution on a glass substrate，the zinc oxide nanoparticles covered the silver nanowire grid and filled the gap of silver nanowire, which enhanced the adhesion of silver nanowire to the substrate. The outermost reduced graphene oxide provides protection for the material and improves the stability of the electrode in an air environment. The AgNWs/ZnO/rGO composite electrode prepared has a sheet resistance of about 9.96 ?/sq and a light transmittance of 71% (T550), which has good photoelectric properties. Experimental results show that the composite electrode has long-term stability in air.
