Abstract

The use of nanoparticle colloids for spray deposition of Cu-In-Se precursor films and subsequent thermal treatment to form CuInSe₂ (CIS) films has been investigated. In the present study, the metathesis reaction between Na₂Se in methanol and metal salts (i.e., Cu(BF₄)₂ and/or InI₃) in pyridine produced CuSe, In₂Se₃, and CuInSe_2.5 nanoparticle colloids. Purified colloid was sprayed onto heated molybdenum-coated sodalime glass substrates to form CuInSe_2.5/Mo and In₂Se₃/CuSe/Mo precursor films. These precursor films were subjected to various thermal treatments in an effort to produce large-grained CIS films from the nano-sized precursors. The annealed CIS films were characterized by scanning electron microscopy (SEM) and x-ray diffraction (XRD). Results of this continuing effort will be discussed.
