The natural dye containing anthocyanin was extract ed from lycium ruthenicum murrdye in Tibetan Plateau.The ferulic acid,oxalic acid and caffeic acid were used as the acyl donor in the acylation of lycium ruthenicum murrdye dyes and applied i n dye-sensitized solar cell.The dyes were characterized by Uv-vis spectroscopy and cyclic voltam metry.It turned out that the acylated lycium ruthenicum murrdye dyes could attach more resultful to the surfa ce of TiO_2film than lycium ruthenicum murrdye dyes.Thus,the electron injection from the dyes in to TiO_2conduction band was feasible.Futuremore,the caffeic acid acylated dyes exhibit o ptimal photo-absorption efficiency.The acylation of lycium ruthenicum murrdye d yes exhibits an impressive power conversion efficiency.An efficiency as high as 1.01% has been achieved under AM 1.5G,100mW·cm－2 by the caffeic acid acylated dyes.The internal resistan ce of the DSSC was analyzed by electrochemical impedance spectroscopy,indicating an effective suppression of the electron rencombination.
