Description
Summary:A simple direct electrochemical approach from materials-science point of view is presented for preparing tin oxide nanoparticles. Advanced structural, chemical, optical and morphological characterizations are employed for analysis. The electrode is composed of ~12nm spherical tin oxide nanocrystallites, which showed current density of 5.472mAcm−2 with nearly 1% power conversion efficiency. The need for better fundamental understanding of the characteristics for improving tin oxide-based dye-sensitized solar cells is emphasized. ► The room temperature synthesis of SnO2 nanocrystallites by a simple and cost-effective electrodeposition has been carried out. ► SnO2 confirmed ~12 nm nanocrystallites and polycrystalline nature from the HR-TEM photo-image and XRD spectrum, respectively. ► ~ 1% power conversion efficiency and 15% IPCE are obtained.
