Hematite nanorods doped with ruthenium were successfully deposited on fluorine doped tin oxide (FTO) glass substrates using aqueous chemical growth. Using complementary surface/interface investigation techniques, the Ru incorporation in the Ru-α-Fe2O3 nanorods was evidenced. The optical band gap was found to be Ru doping concentration dependent: varying from 2.32 (2) to 2.47 (2) eV. These band gap values are well suited for the targeted water splitting process without application of an external bias.

AbstractAntimony-doped tin oxide (ATO) nanoparticles (NPs) (Sb-doped content 3%, 10%, and 15%) were synthesized by the (2 l autoclave, medium-scale) solvothermal method followed by sintering at various temperatures (500°C, 800°C, 900°C and 1000°C) so they would crystallize. The particle size increased from several to tens of nanometers with the increase of sintered temperature from 500°C to 1000°C, sharply from 800°C to 1000 °C; ~30 g of final product was received for each experiment. More interestingly, the crystallinity of the as-synthesized ATO was also increased with the increasing Sb doped content from 3% to 15%. The ATO NPs were coated onto glass substrates and then sintered at 500°C, which effectively prevented transmittance of infrared (IR) wavelengths (>800 nm) with 10% wt Sb-doped content, which is useful for thermal insulated glass coating application.

Dye-sensitized solar cells (DSSCs) have attracted many researchers because it has potential to supplement and compete with other solar cell technologies like Silicon (Si) and Cadmium Telluride (CdTe). The fabrication of DSSCs requires a photo electrode and a counter electrode of transparent and conducting nature. The commercial DSSCs uses electrodes of fluorine doped tin oxide (FTO) glass substrates. These electrodes are expensive and hence, possible alternative materials that are cheaper and that would provide better performance under similar environmental condition should be explored. In this paper, titanium (Ti)-coated glass substrates were prepared and then used to prepare electrodes for fabricating DSSCs. Similarly, DSSCs were fabricated using electrodes of conventional FTO-coated glass substrates. Performance characteristics like cell efficiency (η%), fill-factor (FF), short circuit current density (JSC) and open circuit voltage (VOC) of both fabricated DSSCs were obtained using their respective J-V characteristic curves under similar illumination of 100 mW/cm2 and with comparable transmittance under the visible transmission spectrum of 300-850 nm. The obtained results showed that DSSCs prepared using electrodes of FTO coated glass substrates have 1.557 times better cell efficiency and 2.172 times better fill factor than that of DSSCs fabricated using electrodes of Ti-coated glass substrates.

Transparent conducting Cobalt-fluorine co-doped tin oxide (SnO2: (Co, F)) thin filmswere deposited onto preheated glass substrates using the chemical spray pyrolysis method. The ([Co2+]/[Sn4+]) atomic concentration ratio (y)in the spray solution was varied between 0 and 5 at. %. The structural, electrical, optical and photoluminescence properties of these films were studied. It is found that the thin films are polycrystalline with a tetragonal crystal structure corresponding to SnO2 phase having a preferred orientation along the (200) plane. Transmission and reflection spectra reveal the presence of interference fringes indicating thickness uniformity and surface homogeneity of the deposited thin films. The electrical resistivity (ρ), volume carrier concentration density (Nv), surface carrier concentration density (Ns) and Hall mobility (μ) of the synthesized thin films were determined from the Hall Effect measurements in the Van der Paw-configuration and the following results were obtained: n-type conductivity in all deposited films, a low resistivity of 1.16×10-2 Ω.cm, and a high Hall mobility of 15.13×102 cm2.V-1.s-1with Co concentration equals to 3 at. %. These results show that the electrical properties of these thin films where greatly improved making them suitable as ohmic contact in photovoltaic application devices.

Indium tin oxide (ITO) films were deposited on glass substrates by magnetron sputtering. Properties of ITO films showed a dependence on substrate temperature. With an increasing in substrate temperature, the intensity of XRD peak increased and the grain size showed an evident increasing. The results show that increasing substrate temperature remarkably improves the characteristics of the films. The sheet resistance of 10 Ω/sq and the maximum optical transmittance of 90% in the visible range with optimized conditions can be achicved. The results of experiment demonstrate that high-quality films have been achieved by this technique.
