|Abstract:||Transparent conductive FTO, ATO and ITO films were synthesized by spray pyrolysis technique on flat 12x12 cm borosilicate glass substrates at 500-550°C and investigated with respect to their electrical and optical properties. The resistivity of sprayed ITO films decreases with the thickness down to 3.0x10-4 Ω cm (300 nm). The optical transmission in the visible range is 80% and the near IR reflection up to 96% for thicknesses larger than 300 nm. A reducing treatment at 400°C in forming gas still decreases the resistivity by a factor of two. Bending of the coated glasses in air at 650°C for 1.5 h increases the resistivity of the coatings on the tensile side of the substrate by a factor of 3-4 and by a factor 2 on the compressed side. A subsequent reducing treatment in forming gas at 400°C leads to a drastic decrease of resistivity in both cases by a factor of 5-7 with resulting value Ρ=2-3¡x10-4 Ω cm. ATO layers have lower visible transmission (70-75%) due to stronger absorption and a higher resistivity (Ρ=1x10-3 Ω cm). Spray pyrolyzed FTO coatings have a resistivity Ρ=5x10-3 Ω cm for film thicknesses >350 nm.|
