Sol–gel hydrothermal synthesis of bismuth–TiO2 nanocubes for dye-sensitized solar cell
Source abstract
Abstract
Abstract Bismuth–TiO 2 nanocubes were synthesized via a facile sol–gel hydrothermal method with titanium tetraisopropoxide as the precursor. The influence of the bismuth on the size, morphology, crystallinity and optical behavior of TiO 2 nanocubes were investigated. The samples were characterized by X-ray diffraction analysis (XRD), transmission electron microscopy (TEM), energy dispersive X-ray (EDX), field emission scanning electron microscopy (FESEM) and UV–visible spectroscopy (UV–vis). Photovoltaic behavior of dye-sensitized solar cells (DSSCs) fabricated using Bi–TiO 2 nanocubes was studied. The DSSCs had an open-circuit voltage ( V oc ) of 590 mV, a short-circuit current density ( J sc ) of 7.71 mA/cm 2 , and the conversion efficiency ( η ) of 2.11% under AM 1.5 illumination, a 77% increment as compared to pure TiO 2 nanocubes.
