Solid state dye-sensitized solar cells based on barium strontium titanate nanorod film

Perovskite barium strontium titanate (Ba 0.7 Sr 0.3 TiO 3 -BST) nanorod film was effectively produced and characterized.TiO 2 nanorods were prepared hydrothermally; after that they were deposited on an florine tin-oxide (FTO) substrate at 150 C for 4 h.X-ray diffraction (XRD) showed that the Ba 0.7 Sr 0.3 TiO 3 film was polycrystalline with a low trace of peaks that belonged to TiO 2 , indicating that the BST films needed more reaction time.According to the optical properties, the band gap of the BST nanorod film was 3.16 eV, and strong photoluminescence centered at 367 nm.The data from the BST film can be used to calculate the energy gap.A direct electric current conductivity measurement showed that it increases along with temperature up to the Curie temperature, and the behavior was the opposite.Photoelectrode properties like open circuit voltage, short circuit photocurrent density, fill factor, and efficiency have been measured.The efficiency was 0.071 when preparing solid-state dye-sensitized solar cells based on BST film.
