Novel D-π-A structured Zn(II)-porphyrin Dyes Containing Bulky Alkoxy Substituted Fluorene Derivatives as an Electron Donor Group for Highly Efficient Dye- sensitized Solar Cell |
초록 |
The iodide/triiodide redox shuttle has limited the efficiencies accessible in dye-sensitized solar cells. Here, we report dye-sensitized solar cells that incorporate a Co(II/III)tris(bipyridyl)–based redox electrolyte in conjunction with newly developed D-π-A structured Zn(II)-porphyrin dyes containing bulky alkoxy substituted fluorene derivatives as an electron donor group. The specific molecular design of the Zn(II)-porphyrin dyes greatly retards the charge recombination from the conduction band of TiO2 film to the oxidized cobalt mediator, which enables attainment of high open-circuit voltage associated with high energy conversion efficiency. |
