“…The film doped with 6 at.% of tin is suitable for fabrication of DSSC because it exhibits uniform distribution of spherical grains with large in size, also with the porous nature of the film. The porous films play an interesting role in DSSC in enhancing dye-sensitization when these TiO 2 films are used in solar cell application (Manurung et al 2013;Allah et al 2007). However, at higher doping concentration (8 at.%), the growth of grains is suppressed and segregated due to the presence of compressive stress in the film and it is in agreement with the XRD results.…”

“…At higher wavelength, the refractive index begins to decrease and reaches a constant level which may be due to the presence of high porosity in these films (Tripra Sundari et al 2011). The refractive index of the doped film shows the variation up to 2.65 in the visible region which is preferred for antireflection coating materials in the window layers of the solar cell (Allah et al 2007). …”

Pristine TiO 2 and Sn-doped TiO 2 thin films with different Sn doping levels (2, 4, 6 and 8 at.%) were deposited by employing a simplified spray pyrolysis technique. The XRD pattern of the films confirmed tetragonal structure with the polycrystalline nature. The films exhibited a pure anatase titanium dioxide (TiO 2 ) with a strong orientation along (101) plane. The scanning electron microscopy image of 6 at.% Sn-doped TiO 2 thin film depicted nanosized grains with porous nature. The atomic force microscopy study had shown the columnar arrangement of grains with the increase in particle size and surface roughness for 6 at.% Sn-doped TiO 2 thin films. The optical transmittance was increased with the decrease in the optical energy band gap. The optical constants such as extinction coefficient and refractive index were determined. The intensity of the photoluminescence emission was observed at 398 nm for doped films. The resistivity decreased with the increasing carrier concentration and Hall mobility. The incorporation of Sn into TiO 2 matrix yielded a well-pronounced antibacterial activity for Bacillus subtilis.

“…Therefore, further scan of metal oxide suitable for ESs is necessary. Currently much interest has been focused on zinc oxide (ZnO) due to its excellent optical and electrical properties, which has enabled its application in electronic and optoelectronic devices, such as solar cells, gas sensors, short-wavelength light-emitting diodes [8,9]. However, the potential application of ZnO combined with CNTs as the electrode materials in ESs is seldom discussed.…”

“…In this case, doping can be achieved by simply including an additional doping precursor within the synthesis solution, such as aluminum chloride, tin chloride and silver nitrate. This approach was explored to successfully dope porous ZnO with various elements, including Al [67,68], Sn [69], Ag [70], Na [71], Mg [72] and many others [73,74]. Similarly to pristine ZnO, the resulting doped structures were found to be highly promising in view of gas sensors fabrication, especially for ammonia and H 2 S detection.…”

Zinc oxide (ZnO) thin films have been widely investigated due to their multifunctional properties, i.e., catalytic, semiconducting and optical. They have found practical use in a wide number of application fields. However, the presence of a compact micro/nanostructure has often limited the resulting material properties. Moreover, with the advent of low-dimensional ZnO nanostructures featuring unique physical and chemical properties, the interest in studying ZnO thin films diminished more and more. Therefore, the possibility to combine at the same time the advantages of thin-film based synthesis technologies together with a high surface area and a porous structure might represent a powerful solution to prepare ZnO thin films with unprecedented physical and chemical characteristics that may find use in novel application fields. Within this scope, this review offers an overview on the most successful synthesis methods that are able to produce ZnO thin films with both framework and textural porosities. Moreover, we discuss the related applications, mainly focused on photocatalytic degradation of dyes, gas sensor fabrication and photoanodes for dye-sensitized solar cells.
