“…Electrochemical interface of split in three parallel circuits, additionally the equivalent circuit of DSSC is related to the experimental result of the Nyquist plot as display in Figure 4 In Nyquist plot equivalent circuit in the horizontal axis represent the serial resistance (R 1 ) between wire and substrate, from the impedance spectra represent resistance (R 2 ) and (R 3 ) at interface between electrolyte and Pt counter electrode and as well as between electrolyte and TiO 2 film. On the other side at the interface C 1 shows the double layer capacitance between electrolyte and Pt counter electrode and as well as between electrolyte and TiO 2 film [27,28]. The values of all the parameters of Nyquist plots of DSSC based on TiO 2 photoanode with the equivalent circuit are summarized in Table. In the bode plot of cell based on photoanode TiO 2 under the solar irradiation, the frequency was shifted in higher frequency region with the TiO 2 photoanode as shows in figure 4(b).According to curve recombination charge transfer processes at the TiO 2 /dye/electrolyte interface is low and enhance the electron transmission [29,30].…”

Dye-Sensitized Solar Cells (DSSCs) are prominent alternative devices to conventional p-n junction silicon based solar cells because of their low fabrication cost and high power conversion efficiency, good cost/efficiency ratio. In the present work, DSSC devices were made-up with fluorine doped tin oxide (FTO) glass substrate, a TiO2 compact layer was deposited on FTO, Ruthenium(II) dye (N719), an iodide - triiodide electrolyte and a platinum (Pt) counter electrode. Photo anode with thin film layers of TiO2 and Pt counter electrode (photo-cathode) were prepared. Field emission electron microscope (FESEM) was employed to investigate the surface morphology of TiO2 layers. The DSSC device efficiency was evaluated by J-V characteristics. Fabricated devices were exhibited high power conversion efficiencies. The electrochemical impedance characteristics were analyzed by fitting the experimental results to the corresponding electrical equivalent circuit simulated data.

In this article, novel double-layer films were designed and examined for dye-sensitized solar cells (DSSCs). The commercial titanium dioxide (TiO2) nanoparticles as a bonding underlayer, and the silver nanowires (AgNWs) were used and prepared by means of the polyol method. They which were doped into TiO2 composite materials. The microstructure of AgNWs and the effect of modified DSSCs on photovoltaic (PV) performance were examined. The experimental research indicated that the localized surface plasmon resonance (LSPR) could enhance light-harvesting efficiency. The exceptional electrical conductivity of silver nanowires also improved the interface resistance of DSSCs. We found that LSPR could substantially boost the incident photon-to-electron conversion efficiency (IPCE) of such DSSCs. The AgNWs@TiO2 (an optimized content of 3 wt% in photoanode) improved the photovoltaic conversion efficiency (η) of the DSSCs from 4.01% to 5.88%, when compared with the DSSCs without AgNWs@TiO2 (pure TiO2).

“…In addition, some researchers [15] used GO and magnetic beads (MBs) in the counter electrode for improved photocatalytic activity and to create a fast electro-catalyst through triiodide reduction. Another group of researchers [16] used ferroferric oxide (Fe 3 O 4 ) to apply an active layer, in order to decrease electron recombination. Aluminum (Al) is added to the ZnO, meaning that Zn 2+ is replaced with Al 3+ .…”

In this study, both zinc oxide (ZnO) nanorods and aluminum-doped zinc oxide (AZO) nanosheets were deposited by hydrothermal growth on fluorine-doped tin oxide (FTO) glass. After a photoanode was added to ZnO nanorods or AZO nanosheets, the photovoltaic conversion efficiency (PCE) increased due to improved electron transport and enhanced dye absorption. The improvement in electron transport was verified by electrochemical impedance spectroscopy (EIS), and the increase in dye absorption was verified by ultraviolet-visible spectroscopy. Both of these factors facilitated an increase in PCE. Parameters for dye-sensitized solar cells (DSSCs) using ZnO nanorods/TiO2 and AZO nanosheets/TiO2 photoanodes were tested and the results were recorded using EIS. The results indicated that the addition of the ZnO nanorods increased the short-circuit current density (Jsc) from 9.07 mA/cm2 to 10.91 mA/cm2, the open circuit voltage (Voc) from 0.68 V to 0.70 V, and the PCE from 3.70% to 4.73%, respectively. When the DSSCs were produced in a parallel silver-grid device, the results showed that PCE could be increased from 3.67% to 4.04% due to the reduction in connection resistance.
