“…It is observed from the FESEM analysis that ZGR 0.25 based electrode (Fig. 6b) possesses higher porosity as compared to the electrode fabricated using ZGR 0 and more porosity would result in the enhancement of the surface area that lead to more dye adsorption and the improvement of the photoelectric properties of electrode fabricated from ZGR 0.25 nanocomposite [22,38]. Moreover, the porosity increases and aggregation starts with increase in concentrations of graphene such as in ZGR 0.5 and ZGR 1, as shown in Fig.…”

“…1a). In the atmosphere at room temperature, a metal-oxide surface will absorb moisture from the air to form adsorbed water which eventually is dissociated into adsorbed hydroxy [22]. The absorption peak at 1419 cm -1 can be attributed to the bending vibration absorption of bridging hydroxyl groups in the product.…”

Flower cluster-shaped ZnO microstructures have been successfully synthesized by a facile hydrothermal approach without further heat treatment using Zn(NO 3 ) 2 . 6H 2 O and NaOH as raw materials and sodium lignosulfonate (SL) as a structure-directing agent. The morphology, structure, and property of the products were characterized by X-ray powder diffraction, fourier transform infrared spectroscopy, scanning electron microscopy, Brunauer-Emmett-Teller nitrogen adsorption-desorption isotherms and photoluminescence spectrum. The photocatalytic activity of the as-prepared samples were evaluated by photocatalytic decolorization of methylene blue aqueous solution at ambient temperature. The results indicated that the prepared ZnO-SL sample exhibited flower clustered morphology, hexagonal wurtzite structure, higher surface areas and better UV and visible photocatalytic activity. Moreover, the ZnO-SL sample showed excellent stability after three photodegradation cycling runs.

“…Recently, different nanostructures such as nanoparticles, nanowires, nanorods, nanospheres, nanoflowers, nanofibres, nanotubes and core-shell structures have been developed to use as the electrode on DSCs without sacrificing the surface for dye loading. Since, the core-shell structured materials plays a crtical role in improving the cell performance, currently a great deal of attention has been focused on the development of such type of materials to use in DSCs [7][8][9][10][11][12]. The limiting efficiency of the dye sensitized solar cells is interfacial recombinations of the injected electrons from photo excited dye with the dye cations or redox couple.…”

“…The energy conversion efficiency of TiO 2 based solar cell can be improved when employing MgO. MgO shell layer can retard the recombination of injected electrons [10]. In the present work, the MgO layer was prepared by solution growth technique from Magnesium nitrate.…”

We demonstrated the construction and performance of dye-sensitized solar cells (DSCs) based on nanoparticles of TiO2coated with thin shells of MgO by simple solution growth technique. The XRD patterns confirm the presence of both TiO2and MgO in the core-shell structure. The effect of varied shell thickness on the photovoltaic performance of the core-shell structured electrode is also investigated. We found that MgO shells of all thicknesses perform as barriers that improve open-circuit voltage (Voc) of the DSCs only at the expense of a larger decrease in short-circuit current density (Jsc). The energy conversion efficiency was greatly dependent on the thickness of MgO on TiO2film, and the highest efficiency of 4.1% was achieved at the optimum MgO shell layer.
