Simple size-controlled fabrication of Zn2SnO4 nanostructures and study of their behavior in dye sensitized solar cells

Abstract

Zn 2 SnO 4 nanostructures were obtained via facile and rapid co-precipitation approach in presence of amines with different long chain as a novel basic and capping agents. The effect of different amines such as NH 3 , ethylenediamine, triethylenetetramine, tetraethylenepentamine on the size of Zn 2 SnO 4 nanostructures were investigated. The results demonstrated that applying the appropriate amount of organic amine could be effective in particle size control. The obtained nanostructure products were specified by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, scanning electron microscopy (SEM), transmission electron microscopy (TEM) , energy dispersive X-ray analysis (EDX) and ultraviolet-visible (UV-vis) spectroscopy. Dye sensitized solar cells (DSSC) were created by the constructed electrodes as working electrode and then were studied by current density-voltage (J-V) curve. It was found that incorporating of TiO 2 nanoparticles to optimized Zn 2 SnO 4 nanostructures has significant role on the constructed DSSCs photovoltaic properties.

SrSnO3-Assembled MWCNT Heterojunctions for Superior Hydrogen Production under Visible Light

“…In recent years, perovskite semiconductors have been shown to possess properties that can be utilized in wide range applications in renewable energy and environmental remediation. − Perovskites have been applied in water splitting and photocatalytic degradation of toxic compounds. − For example, alkaline-earth stannates are ferromagnetic perovskites with distinctive properties as they are piezo- and pyroelectric materials. These properties allow their utilization in capacitors, photoluminescent devices, sensors, many electronic devices, and as photocatalysts. − SrSnO 3 has a three dimensional crystal structure in which SnO 6 octahedral and SrSnO 3 octahedral distortions promote electron/hole mobility and separation, yielding effective photocatalysis as has been shown in several studies of organic pollutant degradations. − SrSnO 3 was also used in humidity sensors, lithium ion batteries, thermal capacitors, and in electronic devices …”
