ZnO∶(Al, Sm)阻挡层薄膜的制备及其光电性能
Preparation and Photoelectric Property of ZnO∶(Al, Sm) Block Films
摘要
Abstract
Al and/or Sm doped ZnO block films were prepared by sol-gel method, and characterized by XRD, EDS, FTIR, PL, 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 TiO2 (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/cm2 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.关键词
