“…The excitons absorbed in the inorganic semiconductor material produce the photogeneration of charge carriers. The light absorption profile and wide band gap nature of inorganic semiconductor material can be modified by quantum confinement effect [11][12][13][14][15][16]. By taking the advantages of this way, researchers can effectively increase the harvesting capacity of dye molecules and power conversion efficiency of dye-sensitized solar cell.…”

The present research study focuses upon the synthesis, characterization, and performances of optoelectronic properties of organicinorganic (hybrid) ZnO based dye sensitized solar cells. Initially, polymer dye A was synthesized using condensation reaction between 2-thiophenecarboxaldehyde and polyethylenimine and was capped to ZnO nanoparticles. Size and morphology of polymer dye A capped ZnO nanoparticles were analyzed using DLS, SEM, and XRD analysis. Further, the polymer dye was added to ruthenium metal complex (RuCl 3 ) to form polymer-ruthenium composite dye B. Absorption and emission profiles of polymer dye A and polymer-ruthenium composite dye B capped ZnO nanoparticles were monitored using UV-Vis and fluorescence spectroscopy. Polymer dye A and polymer-ruthenium composite dye B capped ZnO nanoparticles were further processed to solar cells using wet precipitation method under room temperature. The results of investigations revealed that, after addition of ruthenium chloride (RuCl 3 ) metal complex dye, the light harvesting capacity of ZnO solar cell was enhanced compared to polymer dye A capped ZnO based solar cell. The polymer-ruthenium composite dye B capped ZnO solar cell exhibited good photovoltaic performance with excellent cell parameters, that is, exciting open circuit voltage ( oc ) of 0.70 V, a short circuit current density ( sc ) of 11.6 mA/cm 2 , and a fill factor (FF) of 0.65. A maximum photovoltaic cell efficiency of 5.28% had been recorded under standard air mass (AM 1.5) simulated solar illuminations for polymer-ruthenium composite dye B based hybrid ZnO solar cell. The power conversion efficiency of hybrid ZnO based dye sensitized solar cell was enhanced by 1.78% and 3.88% compared to polymer dye A (concentrated) and polymer dye A (diluted) capped ZnO based dye sensitized solar cells, respectively. The hybrid organic/inorganic ZnO nanostructures can be implemented in a variety of optoelectronic applications in the future of clean and green technology.

“…Generally, it contained counter electrode 1 , redox electrolyte and dye-modified wide band semiconductor electrode such as zinc oxide 2 nanostructure. ZnO films have been prepared by several deposition techniques including hydrothermal technique [3][4][5][6] , chemical bath deposition [7][8][9] , sol gel technique 10 , spin coating 11 , pulsed laser deposition 12 , spray pyrolysis [13][14][15][16] , thermal evaporation 17 , dip-coating method 18,19 and radio frequency magnetron sputtering 20 as reported in many literature reviews. Dye sensitized solar cell has many benefits such as low production cost 21,22 , simple manufacturing process, flexibility 23 and high conversion efficiency 24 .…”

This review paper focuses on the preparation of zinc oxide nanostructures using electrodeposition method for dye sensitized solar cells. Electrodeposition method has been selected in this study due to many advantages if compared to other deposition techniques. During the deposition process, the nucleation rate can affect the structure and morphology of films. As results, experiment findings indicate that the nanoporous films with large surface area could be successfully produced using this method.

“…In particular, the morphology of the semiconductor film affects the overall efficiency of the solar cell [18]. Among all other techniques, crack-free and compact thin films can be achieved most readily by the spray technique and screen printing [19]. In 2007, Suh et al [20] prepared ZnO thin film photoanode immersed in N719 dye for 24 h at room temperature reached 0.34 % efficiency for the pillarshaped ZnO nanowire DSSCs and 0.46 % for branched structure of ZnO nanowires.…”

ZnO films have been prepared on glass plates with concentrations of 0.025, 0.05 and 0.1 M each consisting of 50 ml of solution using the spray pyrolysis technique. A dye-sensitized solar cell (DSSC) was constructed by means of the obtained film for 0.1 M which was also coated above the ITO substrate. N-719, iodide and platinum-coated ITO glass plates were used as the dye, electrolyte and counter electrode, respectively. XRD confirms that the structure of the film was polycrystalline having wurtzite structure. The surface with pores was found from the FESEM studies. The DSSC shows an optical transmittance of approximately 70 % in the visible region. The photoluminescence study reveals the electronic structure of the material. The efficiency of the DSSC measured for a 0.1 M ZnO thin film by sensitizing every 2 h was g = 0.51, 0.80, 0.54, 1.12, 2.11, 2.71, 3.15 and 3.20 %, respectively.
