Abstract

Al and/or Sm doped ZnO block films were prepared by sol-gel method

and characterized by XRD

EDS

FTIR

UV-Vis and SEM to investigate the effects of Al and Sm doping content on the performance. When the doping mole fraction of Al is 1%

and that of Sm is 3%

the photoluminescence intensity of the block film is the highest. The film can down-convert part of ultraviolet light to visible light of 588 nm

which widens the spectra response range. By using ZnO:Al

Sm down-conversion film and TiO

(P25) porous absorbing layer

after sensitized by the pigment ethanol solution of spines of sea urchin

the short-circuit current density and open-circuit voltage of the dye sensitized solar cell (DSSC) are 0.68 mA/cm

and 0.73 V

respectively. And the DSSC achieves the power conversion efficiency of 0.33%

which is increased by 136% compared to the DSSC based on ZnO block layer.
