ABSTRACT
Perovskite Barium strontium titanate (Ba0.7Sr0.3TiO3 (BST)) nanorod film has been effectively produced and characterized hydrothermal. Prepared TiO2 nanorods hydrothermally; after that, they were deposited on an FTO substrate for 150 °C at four h. X-ray diffraction (XRD) showed that the Ba0.7Sr0.3TiO3 film was polycrystalline with a low trace of peaks that belonged to TiO2, 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 centred at 367 nm. The data from the BST film can be used to calculate the energy gap (Eg). A DC conductivity measurement showed that it increases with increasing temperature up to the Curie temperature, and the behaviour was the opposite. Photoelectrode properties like open circuit voltage (Voc), short circuit photocurrent density (Jsc), fill factor FF, and efficiency have been measured. The efficiency was 0.071 when preparing Solid-state dye-sensitized solar cells (ss-DSSCs) based on BST film.
