“…Similar kind of observations was also reported by Kosemen et al [22] by modifying the surface of TiO 2 with Fe. This increase in efficiency can also be attributed to a reduction in recombination of electron-hole pairs, which leads to enhance charge separation.…”

“…Many people have worked in this direction and could obtain an increase in overall efficiency. [20][21][22][23] Shi et al [24] have conducted their studies to improve the conversion efficiency of a solar cell by coating with an amorphous Si layer with a thickness of 2 nm in order to passivate the Si/polymer interface in the device. By doing this, they could show an improvement short-circuit current density to 83% and conversion efficiency increased from 5.8 to 7.1%.…”

In the present work, an improvement in light‐conversion efficiency by coating spherical particles of mesoporous TiO2 (MT) and copper‐modified mesoporous TiO2 (CMT) on single‐crystalline Si solar PV cell is observed. The studies are carried out by spin coating with different concentrations of MT (0.25 to 1.5%) and CMT (0.25 to 1.0%) particles on bare cells independently and compared with a bare solar cell throughout the work. It is observed that in the case of MT coatings, the conversion efficiency increases initially and reaches a maximum of 9.77% at a coating concentration of 1.0%; thereafter, it decreases with an increase in coating concentration. This decrease in efficiency may be attributed to coagulation of MT particles, whereas in the case of CMT particles the conversion efficiency reached a maximum of 8.85% at 0.5% concentration and decreases thereafter. This study indicates that a higher efficiency can be achieved at lower concentrations of CMT coating compared to MT coatings on a bare solar cell. The increase in efficiency may be attributed to better surface passivation and/or trapping of electrons at the metal sites by Cu in CMT. Recombination lifetime measurements results corroborated that CMT particles show better surface passivation as a result of which there is an increase in efficiency. Diffused reflectance and short‐circuit current ratio versus wavelength studies on MT and CMT also revealed that CMT particles perform better than MT particles.

“…Recently, special attention has been given to TiO 2 and ZnO NPs due to their unique optical, electrical, and chemical properties. TiO 2 is a tremendous photocatalyst, which is widely used for antibacterial activity due to its high photosensitivity, high efficiency, nontoxic nature, strong oxidizing power, relative cheapness, and chemical stability [15]. ZnO is also a promising photocatalyst and plays a pivotal role in antibacterial activity.…”

We report in this paper antibacterial activity of Ag-doped TiO2 and Ag-doped ZnO nanoparticles (NPs) under visible light irradiation synthesized by using a sol-gel method. Structural, morphological, and basic optical properties of these samples were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectrum, and UV-Vis reflectance. Room temperature X-ray diffraction analysis revealed that Ag-doped TiO2 has both rutile and anatase phases, but TiO2 NPs only have the anatase phase. In both ZnO and Ag-doped ZnO NPs, the hexagonal wurtzite structure was observed. The morphologies of TiO2 and ZnO were influenced by doping with Ag, as shown from the SEM images. EDX confirms that the samples are composed of Zn, Ti, Ag, and O elements. UV-Vis reflectance results show decreased band gap energy of Ag-doped TiO2 and Ag-doped ZnO NPs in comparison to that of TiO2 and ZnO. Pathogenic bacteria, such as Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli, were used to assess the antibacterial activity of the synthesized materials. The reduction in the viability of all the three bacteria to zero using Ag-doped ZnO occurred at 60 μg/mL of culture, while Ag-doped TiO2 showed zero viability at 80 μg/mL. Doping of Ag on ZnO and TiO2 plays a vital role in the increased antibacterial activity performance.

“…The power conversion efficiency of Al-doped TiO 2 cell is superior than mesoporous TiO 2 coated cell [12]. Similarly, many authors have reported an improvement in solar cell efficiency by overcoating on solar cells with Co, Cd, Fe, Zn, Gd, Eu doped TiO 2 thin films with different doping concentrations [13][14][15][16][17][18].…”
