Abstract
The AgInS2 polycrystalline films were grown on glass substrates by using sulfurization of evaporated metal precursors. New procedures for the growth of AgInS2 films are presented. The influences of [Ag]/[In] molar ratio in the precursor films on structural, optical, electrical performances of films have been investigated. The X-ray diffraction patterns of the samples demonstrate the presence of polycrystalline structures of AgInS 2 phase in these films. The band gaps and carrier densities of these samples determined from transmittance spectra and electrochemical analysis are in the range of 1.92∼1.94 eV, and 3.2×1020∼4. 0×1020 cm-3, respectively. The flat band potentials of these samples are located between -0.83 and -1.10 V versus normal hydrogen electrode with the Mott-Schottky measurements. The maximum photocurrent density of samples prepared in this study with external potential kept at +1.0 V (vs. Ag/AgCl electrode) was found to be 4.4 mA/cm2 under the illumination with white light intensity kept at 100 mW/cm2.
