Effect of Al-doped on physical properties of ZnO Thin films grown by spray pyrolysis on SnO2: F/glass

“…This will allow us to use 1 at. % aluminum doped zinc oxide thin films as optical window in photovoltaic cell such as Au/CuInS 2 /AZO/SnO 2 :F where the growth by spray of SnO 2 :F et CuInS 2 thin films is well controlled in our laboratory [7,8,28,29]. In perspective to optimize the performance of ZnO i.e good cristalinity, tranparent and conducting films, the study of the influence of tin dopant on the physical characteristics of chemically sprayed ZnO is in the course of realization.…”

“…Fluorine doping was achieved by adding fluoride NH 4 F. Next, FTO samples, heated also at 440°C, are then coated by ZnO thin layers with a distance samples-nozzle of 27 cm and a spray rate of 25 ml.min -1 , during 40 min spray time. The spray solution consisted of zinc acetate, H 2 O and propanol-2 (C 3 H 8 O) [7,8]. We added a few drops of acetic acid to make the solution transparent.…”

“…The distance samples-nozzle is about 27 cm and the time of spray is 4 min. The solution used for pulverization consisted of tin tetrachloride (SnCl 4 ), methanol (CH 3 O) and double distilled water (H 2 O) [7,8]. Fluorine doping was achieved by adding fluoride NH 4 F. Next, FTO samples, heated also at 440°C, are then coated by ZnO thin layers with a distance samples-nozzle of 27 cm and a spray rate of 25 ml.min -1 , during 40 min spray time.…”

“…The experimental set up has been previously described [7,8]. The thin films of SnO 2 :F were sprayed onto the substrate glass kept at a temperature 440°C with a spray rate of 25 ml.min -1 .…”

“…These advantages are of considerable interest for practical applications such as, gas sensors [1,2], piezoelectric devices [3], surface acoustic wave devices [4], solar cells [5][6][7][8],etc. Recently, ZnO thin films have been used as a window layer and contact layer for thin film solar cells with Cu(In,Ga)S 2 or Cu(In,Ga)Se 2 absorber material.…”
