“…From the data, it is clear that (N719) with TiInCrO 6-based cell gives the most brilliant performance with the use of dye as sensitizer reunite the highest value of short-circuit current density, Jsc (4.1 mA/cm 2 ), open-circuit voltage, Voc (500 mV), fillfactor, FF (0.94 and efficiency, g (1.7 %). It is observed that the effectiveness of doped photoelectrode-based cell is much higher than TiO 2 (Liu et al 2010;Zhang et al 2011).…”

In this article, we reported the highly reusable undoped titanium dioxide and doped TiInCrO 6 nanomaterial by simple precipitation method and sonication technique. The prepared nanomaterials were characterized by X-ray diffraction, field-emission scanning electron microscopy with elementary dispersive X-ray, high-resolution transmission electron microscopy, techniques and ultraviolet and visible-diffuse reflectance studies. The influence of operational parameters such as the effect of catalyst loading dye concentration and chemical oxygen demand measurements had also been investigated. The synthesized TiInCrO 6 nanomaterial was proposed as the promising photocatalyst for the degradation of rhodamine B (Rh B) dye and reusability. The mechanism of the photocatalytic effect of the TiInCrO 6 nanomaterial has been discussed. Thus, the use of TiInCrO 6 in water purification showed potential. The photodegradation of Rh B dye was well described by pseudo-first-order kinetics and high quantum yield. The photovoltaic characterization had been studied, cyclic voltammogram measurements. The antibacterial activity of the prepared nanomaterials had been investigated against Gram negative Escherichia coli and Gram positive Staphylococcus aureus bacterial strains.

“…From Tables 3 and 4, it is noticed that the efficiency of doped photoectrode based cell is much higher than that of pure photoelectrode based cell, because of the amount of chemisorptions of dye molecules on doped TiO 2 is much higher than of pure TiO 2 [5].Therefore, from the table, the FF and g % for the dye HR and HS-sensitized 6 at.%Sn-doped TiO 2 photoelectrode in I -/I 3 -electrolyte is purely due to the sensitization of dye to 6 at.% Sn-doped TiO 2 photoelectrode; making available maximum charge carriers and providing easy path for transport of charge carriers [44].…”

In this work, highly oriented pure and tindoped titanium dioxide (Sn-doped TiO 2 ) with porous nature photoelectrodes were deposited on ITO glass plates using spray pyrolysis technique. The XRD pattern revealed the formation of anatase TiO 2 with the maximum intensity of (101) plane while doping 6 at.% of Sn. The morphological studies depicted the porous nature with the uniform arrangement of small-sized grains. The presence of tin confirmed with the EDX spectra. The size of particles of 13 nm was observed from high resolution transmission electron microscopy analysis. The average transmittance was about 85 % for the doped photoelectrode and was observed for the photoelectrode deposited with 6 at.% of tin with decrease in the energy band gap. The PL study showed the emission peak at 391 nm. The maximum carrier concentration and Hall mobility was observed for the photoelectrode deposited with 6 at.% of tin. With these studies, the DSSCs were prepared separately with the dye extracted from Hibiscus rosasinesis and Hibiscus surattensis and their efficiency was maximum for the DSSC prepared with 6 at.% of tin.

“…They showed that the doped layer prepared by nanocluster deposition had a conversion efficiency of about 8.92%. Zhang et al [14] synthesized Zn-doped TiO 2 microspheres by introducing a trace amount of zinc nitrate hexahydrate to the reaction system and reported that the DSC based on 0.5 at% of Zn had the maximum efficiency of 4.63%. Huang et al [15] prepared porous nanocrystalline Zn-doped TiO 2 materials employing agarose gel as a template and reported that the DSC containing 0.5 at% Zn had a higher efficiency of 7.6% as compared to the undoped cell (i.e., 6.7%).…”
