Silver (Ag) doped ZnO (SZO) nanomaterials were synthesized by hydrothermal method and characterized. ZnO nanostructures were doped with 0.0%, 0.5%, 1%, 1.5mol% Ag. These obtained SZO nanomaterials were analyzed using X-ray diffraction measurement (XRD), Scanning Electron Microscopy (SEM), and Energy Dissipative X-ray (EDX) spectroscopy. The structural analysis confirmed the formation of synthesized SZO samples having a hexagonal ZnO wurtzite phase. The morphology of SZO samples changed partially and the ZnO nanorod length increased somewhat as the Ag doping ratio increased. Despite this increase, it was seen that the average crystal sizes first increased and then decreased. The crystallite sizes calculated from XRD data for 0.0, 0.5, 1.0 and 1.5mol% SZO were obtained as 41, 42, 38 and 37 nm, respectively. Ag doping concentration has increased the absorbance of SZO nanomaterials increased and the transmission decreased was observed. The band gap of the 0.0%, 0.5%, 1.0% and 1.5mol% SZO nanomaterials were measured 3.19, 3.18, 3.16 and 3.19 eV, respectively. Then dye sensitized solar cells (DSSCs) were fabricated using these SZO nanomaterials, cis-Bis(isothiocyanato)(2,2′bipyridyl-4,4′-dicarboxylato) (4,4′-di-nonyl-2′-bipyridyl) ruthenium (II) dye (Z907), (Ditetrabutylammonium cis-bis(isothiocyanato) bis (2,20-bipyridyl-4,40 dicarboxylato) ruthenium (II) dye (N719) and examined their photovoltaic performances. The calculated efficiencies of DSSCs fabricated using Z907 dye for 0.0%, 0.5%, 1.0% and 1.5mol% SZO were 0.005, 0.51, 0.46 and 0.22%, respectively. Then the calculated efficiencies of DSSCs fabricated using N719 dye for 0.0%, 0.5%, 1.0% and 1.5mol% SZO were 0.06, 0.17, 0.07 and 0.06%, respectively. In both works, DSSCs with ZnO film doped with 0.5mol% SZO showed the best photovoltaic performance. Consequently, these results indicated that the synthesized SZO nanomaterial for DSSCs of the optimum ratio of Ag doping is 0.5mol% clearly.

“…It was thus evident that silver ions were deposited by simple soaking in an aqueous AgNO 3 solution on the surface of 8 h-grown ZnO nanorods. It was reported that an improved PCE was achieved when Ag-incorporated ZnO was applied to DSCs [15][16][17][18][19][20]. In those reports, Ag was used in the form of nanoparticle (metal) or as a dopant.…”

ZnO nanorods were formed by chemical bath deposition on fluorine–doped tin oxide (FTO) glass and the photovoltaic performance of ZnO-based dye-sensitized solar cells (DSCs) was investigated. A DSC with 8 h-grown ZnO nanorods showed a higher power conversion efficiency (PCE) than devices with 4, 6, and 10 h-grown ones. Further improvement in PCE was achieved in a cell with a silver-ion-deposited ZnO/FTO electrode. By deposition of Ag+ on the surface of the 8 h-grown ZnO nanorods, the dye-loading amount increased by approximately 210%, compared to that of pristine ZnO nanorods, resulting in a 1.8-times higher PCE. A DSC with the pristine ZnO/FTO electrode showed a PCE of 0.629%, while in a device with the silver-ion-deposited ZnO/FTO, the PCE increased to 1.138%. In addition, interfacial resistance at the ZnO/dye/electrolyte was reduced to approximately 170 Ω from 460 Ω for the control cell with the pristine ZnO/FTO. We attributed the higher dye-loading amount in the silver-ion-deposited ZnO/FTO to the electrostatic attraction between the positively charged ZnO and carboxylate anions (–COO−) of the N719 dyes.

“…Singh et al scrutinized the Ag doped ZnO films as photoanodes with different amount of Ag doping. DSSC with 0.5% Ag doped ZnO film got higher power conversion efficiency of 0.44% 71 . The change in efficiency of DSSC by the doping of photoanode material with different metal atoms has been compared in Table 3.…”

Summary During the recent period of time, dye sensitized solar cells (DSSCs) have become an exciting invention to meet our energy demands. Its reasonable cost of production and easy fabrication make it a powerful competent to the conventional solar cells. But non‐achievement of expected efficiency is the key challenge faced by the scientific society. To overcome this, boundless research is going on the revamping of DSSC. Among the four chief parts of DSSC, the photoanodes gain more attention due to its dual function. Scilicet, it act as a charge carrier and as a surface for dye adsorption as well. Hence photoanode modification plays a crucial role in enhancing the power conversion efficiencies of DSSCs. It comprises of wide bandgap semiconducting metal oxides, among which TiO2 stands out with higher efficiency. Likewise in the case of photosensitizers, metal complex based dyes (mainly ruthenium based) take the lead in augmented efficiency. This paper critically reviews the work on all the metal oxides used as photoanode materials, comparing their band gap with the best efficiencies reported for each and analyzing their advantages and disadvantages. An overview of the performance of DSSCs based on different metal atom doped metal oxide photoanode, incorporation of various carbonaceous materials and different passivating agents has been included. Also, the modification in the photosensitizer has been discussed, examining the reports on organometallics based dyes and metal free organic dyes.
