“…The presence of porous on the structures differs from -1.0 to -1.4 V. Films A and B present porous between the nanostructures, while, at film C, those same porous are not seen as regularly and the ZnO is more nodular, which can be explained by the higher deposition potential 18 . Mahalingam et al (2005) reports that those nodular structures are characteristic of the ZnO growth 19 . The ZnO nanosheets in films A and B can be attributed to the concentration of Zn +2 in solution, as observed by Yang et al 20 .When increasing the potential, those nanosheets are no longer noticed.…”

Dye-sensitized solar cells (DSSCs) are a feasible option for photovoltaic energy. Zinc oxide is an n-type semiconductor employed as photoanode on DSSCs. ZnO thin films were electrodeposited to study the effects of different potentials applied during deposition. SEM images, XRD and UV-Vis analysis were conducted to reveal the morphologic, structural and optical properties of the films at three potentials. DSSCs were assembled and the photovoltaic parameters were obtained through J-V plots. DSSC with 0.031% of efficiency was demonstrated at -1.4 V of deposition potential.

“…It indicates that the crystallites are grown along the c-axis to the substrate [25]. When the extract is added about 0.01 ml in film (b), the diffraction planes (100) and (101) are emerged more intense compared to (002) plane.…”

Zinc oxide (ZnO) thin films were deposited by spin coating technique onto glass and fluorine doped tin oxide (FTO) conductive substrates. The effect of the Pedalium Murex (P. Murex) leaf extract on their structural, morphological, lattice dynamic and optical properties was investigated. X-ray diffraction studies revealed that the prepared thin films were polycrystalline. The crystalline size, lattice parameter, position parameters, bond length and texture coefficient were estimated from XRD studies. Morphological variations (cordillera, backbone and tree like structure) were observed for films coated with different quantity of extract. Lattice dynamics and defect studies were investigated using micro Raman spectroscopy, which revealed the presence of oxygen vacancies and zinc interstitial in backbone like structure. The excitation and emission spectra revealed that the optical quality of the ZnO thin films depends on defect concentration and excitation energy. Variations in intensity were observed for violet to green emission with deceasing excitation energy. The transmittance spectra of the prepared thin films were recorded using UV-visible spectroscopy. The film prepared with 0.01 ml extract exhibited low transmittance and band gap compared to other films. J-V curves were recorded for film deposited with 0.01 ml extract using polymer and liquid electrolyte as an electrolyte. The effect of the internal resistance was studied for the film deposited with 0.01 ml extract. The open circuit voltage (V oc ), short circuit current density (I sc ) and efficiency (g) of the constructed DSSC were determined.
