A non-vacuum and low-cost route to fabrication of Cu2ZnSnS4 (CZTS) thin film as absorber layer for thin film solar cell is demonstrated. The process involves synthesis of Cu-Zn-Sn composite oxide nanoparticles, preparation of composite oxide ink, deposition of composite oxide thin film and subsequent sulfurization treatment. Cu-Zn-Sn composite oxide nanoparticles with proper composition and particle size can be obtained by controlling the chemical co-precipitation conditions. The effects of sulfurization temperature on the compositional, structural, morphological, optical and electrical properties of the CS thin films were investigated. XRD, Raman and X-ray photoelectron spectroscopy analyses confirmed the formation of CZTS phase after sulfurization. The prepared CZTS thin films exhibit porous morphology and an optical band gap about 135 eV. The solar cells fabricated with the CZTS thin film sulfurized at 550 degrees C showed a conversion efficiency of 1.22%. (C) 2013 The Authors. Published by Elsevier B.V. All rights reserved.
