“…By doping Ga into the seed layer, the short-circuit density is improved about 1.9 times and the conversion efficiency is increased by 86.36% compared with the undoped film in this paper. Nayeri et al [18] also found that the Al doped ZnO seed layers (AZO) could improve the performance of DSSCs based on ZnO nanorods, while the J sc =2.01 mA/cm 2 , η=0.34% of AZO cell and the J sc =0.99 mA/cm 2 ，η=0.13% of undoped DSSC are lower than this work.…”

“…However, there is still no systematical demonstration about the effect of doping seed layer on the properties of electron transport and performance of DSSCs. Besides, the poor electrical properties of seed layer might impede electron transport and lead to retard electron collection of the fluorine-doped tin oxide (FTO) substrate [18]. Therefore, it's meaningful to investigate the effects of GZO seed layer on growth of ZnO nanorod arrays and the photovoltaic performance of DSSCs.…”

ZnO-and Mg-doped ZnO samples are prepared by spray pyrolysis on conducting glass substrates to fabricate ZnO-based dye-sensitized solar cells (DSSCs). Influences of Mg-doping content on the power conversion efficiencies of ZnO-based DSSCs are investigated. X-ray diffraction results show that all the samples exhibit a hexagonal wurtzite structure. Scanning electron microscopy data indicate that the ZnO sample has uniform rods with 1 µ m diameter.With respect to ZnO, the band gap value of 4 at.% Mg-doped ZnO samples improves to the value of 3.27 eV and a further increase in Mg level up to 6 at.% gives rise to a decline in the band gap value of 3.22 eV. Photoluminescence measurements illustrate that intensities of the ultraviolet peak and a red luminescence peak take their maximum values for 4 at.% Mg doping. From solar cell performance measurements, the best power conversion efficiency of 0.08% is obtained for the doping amount of 4 at.% Mg.

“…It should be noted in the context of the undertaken research efforts that ZnO exhibits a whole range of promising properties, which can be utilized in optoelectronic applications (Chen et al, 2009), in sensors (Ates et al, 2013;Minh et al, 2013;Yin et al, 2014), light conversion (Baek et al, 2012;Nayeri et al, 2013), and drug delivery (Zhang et al, 2011). It decomposes dissolved organic impurities under UV irradiation (Colmenares et al, 2015) and exhibits antibacterial effects (Hossain et al, 2014), in particular in the case of E.coli and S.aureus (Jaisai et al, 2012).…”

Hybrid filter material was obtained via modification of polypropylene (PP) nonwoven with nanosize zinc oxide particles of a high aspect ratio. Modification was conducted as a three-step process, a variant of hydrothermal method used for synthesis of nano-ZnO, adopted for coating three dimensional polymeric nonwoven filters. The process consisted of plasma treatment of nonwoven to increase its wettability, deposition of ZnO nanoparticles and low temperature hydrothermal growth of ZnO rods. The modified nonwovens were investigated by a high resolution scanning electron microscopy (HR-SEM). It has been found that the obtained hybrid filters offer a higher filtration efficiency, in particular for so called most penetrating particle sizes.
