The Sb-doped AgIn5S8 films were grown on indium-tin-oxide substrates using chemical bath deposition. The X-ray diffraction patterns of samples show the polycrystalline AgIn5S8 phase in these films. With the molar ratio of Sb/Ag in the Solution higher than 0.2, the conduction type of samples turns into p-type. The thickness, energy band gaps, and carrier densities of these samples are in the range of 692-1119 nm, 1.71-1.73 eV and 5.75 x 10(14) to 9.85 x 10(14) cm(-3), respectively. The maximum photocurrent density of samples with external potential kept at 1.0 V vs. an Ag/AgCl reference electrode was found to be -2.73 mA/cm(2) under illumination using a 300 Xe lamp system.
