Abstract: The Sb:F:SnO 2 layers (AR) were prepared by spray pyrolysis method. The anti-reflective layers (AR) heat-treated at 500°C for 30 min (solution amount 20 cc and 25 cc) have shown an improved crystallinity with crystallite size of 38-39 nm, high optical transmission of around 70 % at 450 nm. Incorporation of anti-reflective layer at cathode interface of SiO 2 /Si(N) devices increased the power conversion efficiency from 1.2% to 2.7% which is mainly contributed from photocurrent enhancement. The enhanced efficien… Show more

This study aims to determine the optical properties of thin films which include absorbance, transmittance, energy band gap, and activation energy characterized by UV-Visible spectrophotometer (UV-vis) with a wavelength of 200-1100 nm. Tin dioxide (SnO2) films are prepared by doping various Fluoride ion (F-) concentrations (0, 5, 10, 15, 20 and 25%) on glass substrates using the sol-gel spin coating method. The absorption edge of SnO2 thin films was found to accrue from 2.90 to 4.41 at 300 nm wavelength when the F- doped concentration increased from 0 to 25%. Furthermore, the transmittance also increased from 65.5 to 97.8% towards the wavelengths from 300 to 350 nm. However, the band gap and activation energies obtained decreased with a percentage increase in fluorine doping. The energy band gap decreased from 3.55-3.41 eV and 3.90-3.84 eV for direct as well as indirect allowed respectively, while the activation energy decreased from 4.04-1.99 eV. The band-gap energy of SnO2 thin films also decreased, and the electrons adjustment from the valence to conduction band caused the conductivity of the film to increase.

The growth of tin oxide thin film by Aluminum doping and Fluorine has been carried out with the sol-gel spin coating technique. The growth aims to determine the quality of the thin layer formed based on variations in doping aluminum and fluorine. The basic ingredients used were SnCl2.2H2O, while the doping materials used were Al (Aluminium) and F (Fluorine) with variations in dopant concentrations (0, 5, 10, 15, 20 and 25)%. The growth of a thin layer using measured glass (10x10x 3) mm as a substrate. The growth of thin films includes substrate preparation, sol-gel making, thin film making, and heating processes. The growth of thin layer was dripped on a glass substrate with sol-gel spin coating technique at 1 M sol concentration and treated with maturation for 24 hours. The next step is making a thin layer using a spin coater at a speed of 2000 rpm for 3 minutes. After that, the substrate is heated in an oven at 100°C for 60 minutes. The results showed that the transparency level of the tin oxide layer increases with increasing amounts of doping Aluminum and fluorine. Key words: Aluminum, Fluorine, Sol-gel, Spin Coating, Thin Film, Tin Oxide
