“…Peak intensity of SnO 2 increases with onion template, which indicates the increase in crystallinity. The crystallite size was determined using Scherrer formula [13] and it was found to be 20 nm and 36 nm respectively for ES9 and OS9. In addition, the pores present in the template could lead to the agglomeration of nuclides inside them and could result in the increased crystallite size compared to the sample prepared without template.…”

This paper reports the role of biological template on the performance of dye-sensitized solar cells (DSSC) fabricated using tinoxide (SnO2) nanoparticles. Herein, onion (Allium cepa) has been employed as the biological template in the synthesis of tin oxide nanoparticles for the first time and is compared with SnO2 prepared without the template. The prepared samples were systematically characterised using the state-of –the art facilities. A sandwich cell was prepared by using the dye soaked SnO2 film acting as the photoanodeand platinum coated on FTO as the counter electrode with I3 ¯ /I ¯ as the electrolyte. Current-voltage (I-V) characteristics have been studied using solar simulator. Performance of DSSC prepared with and without the template is analysed from the measured I-V curves and it is observed that the DSSC prepared using the biotemplate shows better efficiency (9.54%) and fill factor (0.5352).

“…Oxygen deficiency in the lattice is identified from an intense emission at 488 nm and the low intense emissions at 461 nm. In addition to these emissions, existences of low intense green emissions at higher wavelengths were correlated to the recombination of electron sites to the holes at the oxygen vacant sites [18,13].…”

“…Furthermore, the photoresponse in visible-light regions open the possibilities of Sn3O4 activated by sunlight irradiation as the highest visible light source in-universe. Moreover, several works have explored Sn3O4 as advanced material and successfully applied as chemical and gas sensors 11 , anode materials for lithium-ion battery 12,13 , solar cells 14,15 , and photocatalysts 16 . To be specific as photocatalytic material, the visible-light irradiation introduced the electron from valence band to conduction band of Sn3O4, leaving a hole (h + ) at its surface.…”

The SnO2/Sn3O4 were successfully prepared using a one-step hydrothermal method and exhibit the heterostructure formation. The heterostructure formation facilitates the enhancing of visible-light photoresponse of SnO2 which well known as the UV-light activated semiconductor. The heterostructure formation also exhibits high efficient photocatalytic performance by completely degrading 10 ppm of DB71 in 120 minutes after adding 50 mg of prepared-Tin oxide with a kinetic rate constant of 4.636 x 10 -2 min -1 . The kinetic constant rate of prepared-Tin oxide has 2.5 and 3 times faster compared to the kinetic constant rates of SnO2 and Sn3O4, respectively. The high efficient photocatalytic degradation was generated by the improvement of carrier mobilities through manipulating band alignment between SnO2 and Sn3O4 and prevented the recombination of photogenerated hole-electron which commonly generated in the intrinsic semiconductor. Heterostructure SnO2/Sn3O4 was not only forming high-efficiency photocatalytic degradation but also exhibiting blue shifting phenomenon. The UV-Vis adsorption response approaches were used to investigate and propose the photocatalytic degradation mechanism. After 120 minutes, there were only benzene adsorption peaks detected indicating the mineralization of DB71 dyes.

This paper reports the performance of alizarin based SnO 2 dye-sensitized solar cells. A novel template assisted method has been applied for the preparation of tin oxide nanoparticles. For the rst time, onion (Allium cepa) was used as a template for the synthesis of tin oxide nanostructures at different pH values. Tin oxide nanostructures were used for the photoanode preparation. A sandwich cell was prepared by using the dye soaked SnO 2 lm as a photoanode and platinum as a counter electrode. The structural, morphological and optical properties of the nanoparticles were studied using powder X-ray diffraction (XRD), Scanning Electron microscope (SEM), Photoluminescence (PL), Attenuated Total Re ectance (ATR) spectra and UV-visible spectroscopic techniques. Current-voltage (I-V) characteristics have been measured using electrochemical workstation under the presence of solar illumination. Characteristic parameters of the fabricated cell were determined on the basis of the measured I-V curves.
