Abstract:In this work, one type of novel and thick TiO2 array-cluster film was prepared with hydrothermal method which was low cost and simple. It was found that this type of TiO2 film grew on the FTO substrate was a structure of two-layer and had the tetragonal rutile phase from the FESEM images and the XRD patterns. However, the subjacent layer of the two layers was TiO2 array, while the supernatant layer was TiO2 clusters, and both of them were formed from TiO2 rods which developed from finer TiO2 nanorods. The thickness of this type of TiO2 film could reach to 22.9μm, and without any modification treatment, a light-to-electricity conversion efficiency of 1.24% was achieved by using 22.9μm-thick TiO2 array-cluster film which was prepared under the 0.06mol/L-dosage of tetrabutyl titanate (TBOT), at 140℃ for 72h and the FTO substrates placed at 180-degree angle as the photoanode in a DSSC. | |||
