The ISC from 1.142 mA to 0.225 mA, the VOC from 0.551 V to 0.412 V, the ?ll portion from 0.52 to 0.63, and Pmax from 58 lW to 327 lW were obtained from the DSC sensitized with subjective dye extends. In the take outs of intrinsic fruit, leaves and ?ower chosen, the melanize strain extract performed the beat photosensitized e?ect, which was overdue to the better interaction surrounded by the carbonylic and hydroxyl groups of anthocyanin iota on black rice extract and the surface of TiO2 holey ?lm.

The blue-shift of dousing wavelength of the black rice extract in neutral spirits solution on TiO2 ?lm and the blue-shift phenomenon from absorption spectrum to photoaction spectrum of DSC sensitized with black rice extract atomic number 18 discussed in the paper. Because of the simple formulation technique, widely available and wretched specious cost natural dye as an substitute sensitizer for dye-sensitized solar booth is promising. Ã" 2005 Elsevier Ltd.

Introduction Dye-sensitized TiO2 solar cell (DSC) has start an beautiful and cheap device for the metempsychosis of solar twinkle into galvanising energy since Gratzel and OÕRegan ¨ ?rstly report the prototype of this solar cell in 1991 (OÕRegan and Gratzel, 1991).
