Structural and optical studies on antimony and zinc doped CuInS2 thin films

Effect of zinc doping and temperature on the properties of sprayed CuInS2 thin films

“…Improved optical transmission property is observed in the IR regions than the films obtained from vacuum and thermal evaporation methods [43,44] (which are not reported by other researchers). Nearly 70% of light transmission occurs in the IR regions when the substrate temperature is at 300 1C and it increases and reaches 90% as the temperature increases from 325 to 350 1C.…”

“…The influence of Al-doping in CuInS 2 by spray pyrolysis on different substrates is analyzed [23]. A single phase of Sb-doped CuInS 2 can be prepared by annealing the films above 400 1C in Ar (or) N 2 environment [24]. The effect of Na doping on the properties of CuInS 2 thin films has been investigated [25].…”

Influence of mole concentration on nano crystalline Bi-doped CuInS2 thin films with the temperature by chemical spray method

“…Transmission increases gradually as the temperature increases from 300 to 400 • C and maximum of 55% light transmission is noticed at 400 • C. The decrease in transmission for 0.03 M doped samples might be due to the increase in crystallite size [22,23]. However, improved optical property is observed in the case of 0.02 and 0.03 M doped CuInS 2 thin films than the films prepared by thermal and vacuum evaporation methods [20,24].…”

“…Bi doped CuInS 2 thin films recognized to the Bi atoms may occupy volume as well as near the surface of the films [24] and decrease in film thickness or change in structure may also be the reason for improved transmittance (Table 3.1).…”

Low-cost spray-processed Ag 1−x Cu x InS 2 nano-films: Structural and functional investigation within the Lattice Compatibility Theory framework

“…Cu x Ag 1Àx InS 2 thin films [20]. The parabolic shape of E g curves may be attributed to structure degradation for 0.2 < x < 0.6.…”
