Abstract

In2S3 thin films with different S/In molar ratios (from 1.5 to 3.5) were deposited via a spray pyrolysis technique on glass substrates at 340∘C. Then, the obtained films were annealed at the same temperature 400∘C for 2h. X-ray diffraction study reveals the formation of cubic β-In2S3 phase with (400) as preferred orientation. The crystallite size varies in the range 64–97nm. Optical analysis exhibits that transmittance in visible and near infrared regions is higher than 65% for all films. The optical band gap varied from 2.58eV to 2.67eV. The optical parameters (refractive index, extinction coefficient, dielectric constants) were calculated through the transmittance (T) and reflectance (R). Dispersion parameters (E0, Ed), high frequency dielectric constant (ε∞), refractive index (n∞), oscillator length strength (S0), average oscillator wavelength (λ0) and optical moments (M−1,M−3) were determined by Wemple–DiDomenico model. The surface and volume energy losses with photon energy were also calculated. The optical and electrical conductivities were estimated. These properties of In2S3 films are important for photovoltaic applications.
