摘要：

A titanium oxide layer used for a dye-sensitized solar cell (DSSC) has to meet two opponent properties to assure a high efficiency DSSC: good connection between TiO(2) grains and a large inner surface area. Three different paste formulations based on commercial nanocrystalline TiO(2) powder (Degussa P25) are studied. Results confirm that modification of the TiO(2) paste with the Pechini sol-gel method increases the surface area of the TiO(2) layer while maintaining good connections between the nanocrystalline grains, consequently the efficiency of the DSSC increases from 1.8% to 5.3%. The structure and morphology of the TiO(2) layers are described by scanning electron microscopy (SEM), high resolution transmission electron microscopy (HR-TEM) and X-ray diffraction (XRD).
