“…In addition, the dye can also bind easily to the TiO 2 layer to improve the performance of the DSSC. Semiconductors besides TiO 2 , there are also other materials such as ZnO [20], SnO 2 [21], ZnO-CdS [22], ZnO-Fe 2 O 3 [23], and TiO 2 -Ag [24].…”

Research on Dye Sensitized Solar Cell (DSSC) fabrication has been carried out using a combination of dyes extracted from Curcuma xanthorrhiza and Anredera cordifolia. Each dye was extracted by treating pH 1 to 13 and then characterized using UV-Vis spectroscopy. The band gap energy was determined by using the cyclic voltammetric method. The UV-Vis spectrum of C. xanthorrhiza extract reveals the presence of curcumin components. The UV-Vis spectrum of A. cordifolia indicates the presence of chlorophyll and a trace of anthocyanin. C. xanthorrhiza extract had the least band gap energy in the acid phase, pH 1, at 0.66 eV, and the alkaline phase, pH 13, at 0.43 eV. The minimum band gap energy of A. cordifolia extract was determined to be 0.96 eV in the acid phase, pH 7, and 0.65 eV in the alkaline phase, pH 12. When A. cordifolia and C. xanthorrhiza extracts were mixed, with the best composition ratios being pH 7:pH 1 (3:2 ≈ pH 1.7) and pH 12:pH 13 (1:4 ≈ pH 12.6). The composition of this mixture was applied to the DSSC resulting in an efficiency of 0.096 and 0.147%, respectively.

“…There are different methods to prepare TMO semiconductor nanocomposites, including sol-gel method [6,[35][36][37], sonochemical [38,39], hydrothermal [1,10,11], microwave combustion [34,40,41], and coprecipitation [42,43]. Among various chemical methods for synthesis, coprecipitation process has several advantages compare with other methods including, good homogeneity, low cost, high purity of product and not requiring organic solvents.…”

ZnFe2O4/α-Fe2O3/ZnO ternary transition metal oxides nanocomposite powder was successfully synthesized by facile coprecipitation method directly from metalorganic precursors within 4 hours processing time considerably shorter than other reported methods. To study post-synthesis thermal treatment effects on physical properties calcination process was applied at 500 °C, 600 °C and 700 °C individually in furnace for one hour. The structure, phase formation, morphology and optical features of the samples were characterized by means of powder X-ray diffraction, scanning electron microscopy and UV-Visible spectroscopy. The results show formation of pure and homogeneous composites comprised of nanoparticles with good crystallization in narrow range of crystallite size between 25 nm-39 nm. The particle sizes were also estimated to be in the range of 48 nm -93 nm. The optical property was studied by recording the absorbance spectrum in the range of 200 nm -700 nm. The absorption pattern illustrated that the product can be driven by both UV and visible wavelengths with a good efficiency which is more desirable for intended applications like photocatalytic activities compare to the individual components. By using Tauc's method the allowed direct band gap energy and indirect band gap energy of the prepared nanocomposite was estimated to be around 2.28 eV and 2.75 eV, respectively.
