“…Over the past several decades, the use of titanium dioxide (TiO 2 , titania) has been increasing significantly due to its advantages and capabilities for various applications, including the antibacterial disinfection of surfaces, self-cleaning and self-sterilization, site remediation, domestic and industrial wastewater treatments [ 1 , 2 , 3 ]. In addition, TiO 2 is highly chemically-stable and human-friendly [ 4 , 5 ], therefore, it can also be used for biomaterials, biomedical devices and food applications [ 6 , 7 ]. It must be noted that TiO 2 nanoparticles are considered safe: they are used as food additives and for surface coating materials [ 8 , 9 ].…”

In this work, metal-doped titanium dioxide (TiO2) was synthesised with the aim of improving photocatalytic degradation and antimicrobial activities; TiO2 was doped with copper (Cu) ranging from 0.1 to 1.0 wt%. The physical and chemical properties of the Cu-doped TiO2 nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), the Brunauer–Emmett–Teller method (BET) and diffuse reflection spectroscopy (DRS). The results revealed that the anatase phase of TiO2 was maintained well in all the Cu-doped TiO2 samples. No significant difference in the particle sizes or the specific surface areas was caused by increasing Cu doping. However, the band gap decreased continuously from 3.20 eV for undoped TiO2 to 3.12 eV for 1.0 wt.% Cu-doped TiO2. In addition, the 0.1 wt.% Cu-doped TiO2 displayed a much greater photocatalytic degradation of methylene blue (MB) and excellent antibacterial ability for Escherichia coli (E. coli) compared to undoped TiO2. On the other hand, the high Cu doping levels had negative impacts on the surface charge of nanoparticles and charge transfer for OH• generation, resulting in decreasing MB degradation and E. coli photokilling for 1.0 wt.% Cu-doped TiO2.

“…This proves that the conductivity of the semiconductor material (TiO2) increases with the addition of AgSO4. In addition, this also indicates that AgSO4 hybridized to LEG4 dye retains its properties, namely having good conductivity [10,11]. Table . 1.…”

“…Ag metal is a noble metal group that has corrosion resistance properties and has high conductivity. In the previous research stated that Ag-doped TiO2 can increase the performance of DSSC, besides the addition of Ag dopant will inhibit the growth of the rutile phase in the TiO2 semiconductor material [5,11]. From the explanation above, DSSC fabrication has been carried out using LEG4 dye and spin coating method, with the addition of Ag concentration expected to improve DSSC performance.…”

DSSC (Dye-sensitized Solar Cell) has been the subject of much discussion by researchers because of its use and benefits for human life to get electrical energy from renewable sources. Many modifications were made in order to increase its efficiency. One of them is the addition of Ag at various concentrations of Dye LEG4 (D1;D2;D3;D-Ag). Dye LEG4 (triphenylamine) is one of the synthetic dyes synthesized from dyenamo orange (D35) dye and obtained 4 variations of dye, LEG4 is the result of the synthesis which has the highest efficiency. Ag metal was chosen because it has high conductivity properties. The DSSC compound composed of a working electrode (based on FTO glass coated by TiO2 and hybridized using dye LEG4+Ag) and a counter electrode based on FTO glass coated by platinum. DSSC devices arranged in a sandwich is tested for its optical properties by using a UV-VIS spectrophotometer to determine the absorbance curve of dye and to get Gap energy and IV-Meter to determine the efficiency.

“…Table II compares the results obtained from this experiment with other paper works. Kaur et al [34] investigated variable energy density Ag ion implantation of TiO2 photoanodes and fabricated the plasmonic DSSCs with high light-collecting ability. In comparison with the previous results, the improved optimized photoanodes show better photocurrent because AgNWs reduces the interface impedance.…”

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).
