“…The photovoltaic performance of the present study was also compared with the findings of other authors, and the corresponding performance parameters are summarized in Table . The results of the present study with a maximum η of 1.62% for the 9-ZNR-based DSSC are higher than those from the studies of Jiang et al (η = 1.0%) and Chatterjee (η = 1.56%). , The present study also reflects a higher photoconversion efficiency than the those from Fang et al (η = 0.84%), Raja et al (η = 0.74%), and Zhang et al (η = 1.38%). − Still, the photoconversion efficiency was found to be incompetent, and this has been ascribed to factors like dissolution and corrosion of ZnO due to the presence of a carboxylic functional group of the N719 dye.…”

The effects of TiO 2 passivation investigated by I−V measurement are shown in Figure 7b, and the characteristic performance parameters affecting the functioning of DSSCs are listed in Table 1.…”

“…However, Al-Kahlout achieved a higher efficiency of 3.01% using a costly platinum-based counter electrode in comparison to the low-cost Gr:PEDOT counter electrode. Chatterjee in 2018 used the low-cost dye “Rose Bengal” to sensitize ZnO NRs and carbon as the counter electrode to gain η of 1.56%, which is considerably good. Sinha et al, while using the chemical vapor deposition (CVD) technique to synthesize ZnO nanotowers along with chlorophyll as the sensitizing material and carbon as the counter electrode, could only achieve η of 0.13%.…”

Zinc oxide nanorods were grown hydrothermally and used as a photoanodic material in dye-sensitized solar cells (DSSCs). The influence of hydrothermal growth time on the synthesis of ZnO nanorods was expounded by various characterizations, viz., FESEM, EDXS, XRD, FTIR, XPS, and UV−visible spectroscopy. The FESEM imaging ascertained the rod-shape morphology of ZnO. The XRD and FTIR measurements confirmed the formation of the defect-free and crystalline hexagonal wurtzite ZnO nanorod-like structure. The XRD calculations also demonstrated the increase in lattice strain and thereby the length of ZnO nanorods as a result of an increase in the hydrothermal growth time. The purity and surface properties of ZnO nanorods were confirmed by EDXS and XPS. The UV−visible spectroscopy revealed an electronic transition in bandgap energy due to quantum confinement effect, resulting in a decrease in the bandgap energy. The consequences of reaction time were also observed on the photovoltaic parameters of the DSSCs. The DSSC fabricated with the 9-ZNR sample exhibited a maximum efficiency of 1.62%, and hence the optimal time for the growth of ZnO nanorods was confirmed as 9 h. A passivating layer of TiO 2 on ZnO nanorods boosted the efficiency by almost 2-fold, which was ascribed to factors like a decrease in the interfacial charge recombination, a reduction in the dissolution of ZnO, and a reduction in interfacial traps.

“…The photovoltaic performances of the cells were determined via the measurements of maximum voltage (V max ), maximum current (I max ), open-circuit voltage (Voc), short-circuit current (Isc), fill factor (FF), and the power conversion efficiency (η) of the cell. By measuring the current and voltage of the constructed device, it was possible to determine the solar-to-electric power efficiency of the dye-sensitized solar cells [23]. The dye-sensitized solar cell device efficiency was calculated from Figure 4 using the equation, where P max and P in denote the maximum output power and intensity of the incident light, respectively.…”

A plasmonic effect of silver nanoparticles (AgNPs) in dye-sensitized solar cells (DSSCs) is studied. In this investigation, the efficiency of dye-sensitized solar cells has been remarkably increased by infusion of synthesized silver nanoparticles into the TiO 2 photoanode. Rhodaminederivative RdS1 was synthesized by microwave-assisted condensation of hydrazide and 3-formylchromone. The synthesized silver nanoparticles were characterized with UV/Vis absorption spectroscopy and transmission electron microscopy. The interfacial charge transport phenomena of the dye-sensitized solar cell (DSSCs) are determined by electrochemical impedance spectroscopy and the corresponding efficiencies are calculated using current-voltage (I-V) curve. The solar cell photoanode with silver nanoparticles infused with RdS1 in titanium dioxide had the highest solar-to-electric power efficiency at 0.17%.
