DSSC用钒掺杂二氧化钛薄膜的制备及性能表征
Preparation and characterization of V-doped titanium dioxide films used for dye-sensitized solar cell
摘要
Abstract
In order to obtain titanium dioxide film used for high performance Dye-sensitized solar cells (DSSC) the V-doped TiO2 film was prepared by RF magnetron sputtering in this paper.The effects of sputtering time,annealing temperature and amounts of vanadium-doped (V-doped) on the optical properties,photocatalytic properties,super hydrophilicity and electrical properties of the TiO2 film were investigated by spectrophotometer,catalytic reactor and electrochemical workstation.The results showed that the longer the sputtering time,the lower the transmittance of the thin film in the UV region.under the condition of 3 h sputtering time,the transmittance of the sputtered film has been reduced to below 60% in the region of less than 400 nm.The annealing temperature influences the hydrophilicity and photocatalytic properties of the films at a certain degree,and that at 400 ℃ is best.The absorption peak of the film was red shifted and the band gap became more narrow because of the doped V.When the doping amount was 0.5%,the red shift of TiO2 film was the largest and the band gap was 2.88 eV.Then,DSSC was prepared by the V-doped TiO2 thin films.The results showed that the range of the light response of TiO2 thin film increasesed when the amount of doped V is 0.5 %,and the open circuit voltage and short-circuit current are higher than that of the undoped,especially the short-circuit current increasesed from 24.82 to 88.15 μA,which showed that the performances of the cells were improved.关键词
