Synthesis and characterisation of Ag nanowires: Improved performance in dye sensitized solar cells

Publication date: Available online 5 July 2016 Source:Perspectives in Science Author(s): Safia A. Kazmi, Salman Hameed, Ameer Azam Development of highly efficient dye-sensitized solar cells (DSSCs) with good photovoltaic parameters is an active research area of current global interest. Recently, one dimensional nanomaterial, such as nanorods and nanotubes has replaced the nanoparticles used in DSSCs anode because of their ability to improve the electron transport leading to enhanced electron collection efficiency. In the present work, rapid synthesis of Silver nanowires (AgNWs) was done. The XRD characterization was performed to confirm the formation and size of synthesized AgNWs. It was observed that FWHM of the diffraction peaks was increased with AgNWs concentration in TiO2. The synthesized TiO2AgNWs nanocomposite was used as the photo anode of Dye sensitized solar cell. The I-V characteristics of the solar cell were drawn using standard conditions. It was observed that TiO2AgNWs based solar cells have significantly increased photocurrent density resulting in improved conversion efficiency as compared to pure TiO2 based DSSC.
