英文摘要: Abstract(#br)TiO 2 –sulphur composite films have been prepared and employed as photoanode of dye-sensitized solar cell (DSSC). The influence of sulphur precursor content in terms of thiourea concentration on the structural and optical properties of the sample has been investigated. The anatase and sulphur phases exist in the composite. The secondary phases, namely SO 3 and Ti 3 S 4 , also present in the composite. The 0.3 M sample possesses the highest reflection and absorption in visible region. Raman characterization reveals that the peak at 474 cm −1 corresponds to the A 1g symmetric stretching mode of sulphur. The effect of the sulphur precursor concentration on the performance parameters of the device has also been investigated. The DSSC utilizing the sample with 0.3 M thiourea...
