In this work, the composites of Bi4Ti3O12/graphere (BTO/Gr) are used as counter electrode (CE) through facile method based on sol-gel and electrospinning techniques to improve the efficiency of dye-sensitized solar cells (DSSCs). The structure and morphology of the composites with different ratios are characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy...
ZnO is considered as one of the most promising candidate photoanodes for dye-sensitized solar cells (DSCs) for its high electron mobility, suitable energy-band structure and excellent physical properties. However, the efficiency of ZnO based DSCs is quite low due to the poor chemical stability for dye solution and lots of surface defects for high charge recombination. This paper reports a facile surface...
