“…The electronic state of the material is not directly affected by the additive but the gas to be detected is activated to facilitate its catalytic oxidation at the tin dioxide surface. Pd is known to induce this spill-over effect which may also favor the dissociation and adsorption of oxygen at the functioning temperature of the sensors [23]. …”

“…[4][5][6][7][8][9][10] Physical vapor deposition ͑PVD͒ methods have been widely used for the fabrication of tin oxide thin films. [11][12][13][14][15] SnO 2 ceramics are commonly used as source material. Under high vacuum conditions and at high temperatures, the gaseous SnO 2 molecules will dissociate and the film material condensed onto the substrate is primarily oxygen deficient.…”

“…The usage of FTO broadens in various fields of the technology due to its chemical and thermal stability along with the high optical transparency in the visible range and high electrical conductivity. FTO has been prepared by various methods including chemical vapor deposition, 4 pulsed laser deposition, 5 rf sputtering, 6 sol-gel and spray pyrolysis deposition (SPD). 7 The spray pyrolysis is widely used to prepare FTO films, owing to its simplicity, low-cost experimental apparatus arrangement, readily incorporatability of various dopants, high growth rate and high mass production capability for large area coatings and so on.…”

Fluorine-doped tin oxide (FTO) thin films were prepared, at different substrate temperatures, using dilute precursor solutions of di(n-butyl)tin(iv) diacetate (0.1 M DBTDA) by varying the F − concentration in the solution. Morphology of SEM image revels that grain size and its distribution are affected by the substrate temperature. At the lowest temperature (400°C) the grain size become the smallest and at the highest temperature grain size become larger while at moderate temperature it has a large distribution of grain sizes. XPS calculation reveals that fluorine doping will decrease when substrate temperature is increased. Carrier concentration measured from hall coefficient analysis is found to be varying with the amount of fluorine doping as well as with the surface area of the film. Mobility becomes the lowest for the lowest grained FTO and it is the highest for the largest grained FTO. The best film, has large distribution of grain sizes (50-400 nm), gives an electronic conductivity of 31.85 × 10 2 Ω −1 cm −1 , sheet resistance of 4.4 Ω/square with over 80% transmittance (400-800 nm). Optimum conditions of the best FTO film were 0.1 M DBTDA, 0.3 M ammonium fluoride, in a mixture of propan-2-ol and water, at 470°C substrate temperature. Dye-sensitized solar cells were fabricated using both the FTO films thus prepared and with the commercial FTO film. The best efficiency of 6.48% was observed for the cell fabricated from the best FTO films prepared at 470°C whereas the cells fabricated from the commercial FTO shows 5.30% light-to-electricity conversion efficiency (Illumination-A.M 1.5, Cell active area-1 cm 2 , MPN based electrolyte-I − /I 3 − ).
