“…Also in this region reflectivity is lower for the nanostructured case meaning larger absorption contributing to repair SWE damage. Previously reported values of reflectance for antireflection coatings in solar cells are around 25% [23]. The total reflectance obtained by the optimized proposed nanostructure is around 20%, improving absorption on the cell structure.…”

“…This is of importance when proposing ultra-thin front-contact ITO (indium tin oxide) layers that could compromise its electric conductivity. Along the paper we have paid special attention to both absorption, caused by trapping at the proposed nanostructured front layer, and reflectance of the whole cell, which has been reduced with respect to previous reported results [23]. Section 2 of this paper evaluates the contributions of the individual layers of aSi-H solar cell, including the analysis of an optimized flat ARC that combines ITO and Si 3 N 4 .…”

Absorption of amorphous-Si hydrogenated (aSi-H) solar cells can be enhanced by using dielectric nanostructures made of Si 3 N 4 that work like antireflection coatings. The analysis focus on the short-circuit current delivered by the cell under solar irradiance, and it is made taking into account every layer and structure of an aSi-H cell. A customized design of the antireflection coating in the form of nanostructured dielectric layers, produces a short-circuit current enhancement of 15.2% with respect to the reference flat solar cell, and a lower reflectivity of the cell. Three different geometries of linear nanostructures have been analyzed and compared with quite similar results among them. An improvement in performance has been also obtained for realizable geometrical dimensions that could be fabricated while maintaining electric conductivity of the front contact.

“…To achieve this goal, TiO 2 is often doped or mixed with different materials, e.g., nonmetals, metals, metallic oxides, etc., for better photocatalytic performance under direct sunlight (Medina-Valtierra et al, 2009;Li and He, 2013;Suárez et al, 2017). For example, TiO 2 films doped with 5% Ni show an increased light transmission in the visible and NIR regions and lower reflectance (Haider et al, 2016). V-doped TiO 2 :SiO 2 sol-gel ARCs with 15% V-TiO 2 content also demonstrate low refractive index and excellent photooxidative degradation of methylene blue (k 0.033 min −1 ) (Adak et al, 2017).…”

Titanium(IV) oxide (TiO2, titania) is well-known for its excellent photocatalytic properties, wide bandgap, chemical resistance, and photostability. Nanostructured TiO2 is extensively utilized in various electronic and energy-related applications such as resistive switching memory devices, flat panel displays, photodiodes, solar water-splitting, photocatalysis, and solar cells. This article presents recent advances in the design and nanostructuring of TiO2-containing antireflective self-cleaning coatings for solar cells. In particular, the energy harvesting efficiency of a solar cell is greatly diminished by the surface reflections and deposition of environmental contaminants over time. Nanostructured TiO2 coatings not only minimize reflection through the graded transition of the refractive index but simultaneously improve the device’s ability to self-clean and photocatalytically degrade the pollutants. Thus, novel approaches to achieve higher solar cell efficiency and stability with pristine TiO2 and TiO2-containing nanocomposite coatings are highlighted herein. The results are compared and discussed to emphasize the key research and development shortfalls and a commercialization perspective is considered to guide future research.

“…), or metals. The use of transition metals such as Cu, Cr, Ni, V, Fe, for doping TiO 2 has been widely researched [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Although less common, TiO 2 doped with Mo has been shown to have great potential as a photocatalyst [22][23][24].…”

In this study, TiO2 nanoparticles modified with MoS2 were synthesized using the low temperature hydrolysis method. Samples of pure TiO2 and samples of MoS2 /TiO2 were prepared using different amounts of MoS2 (1.0% and 10.0% by weight). The samples were annealed at 500°C and 700°C and characterised by ICP-AES, XRD, Raman, FT-IR, TG, XPS and DR-UV-Vis spectroscopy. The results suggest that the MoS2 added during synthesis is a satisfactory source of Mo to produce doping of the TiO2 structure. In addition, the transformation of anatase phase to rutile is delayed when the concentration of Mo incorporated into the structure increases. Finally, the effectiveness of the synthesized MoS2 /TiO2 samplesused as photocatalyst for the photodegradation of methylene blue dye under visible light irradiation was investigated. TiO2 doped with MoS2 was shown to improve the degradation of methylene blue under visible light. There was found to be an optimal temperature and level of doping to achieve improved photocatalytic activity, in our case 10.0% MoS2 /TiO2 at 700°C.
