The results of monogram CulnSe(2) synthesis from Cu-In alloy and Se in liquid KI are presented. The amounts of CuInSe2 and KI were nearly equal to fulfil the criterion for the monogram growth (all free volume between he particles has to be filled with liquid). All the grown powder materials with narrow-disperse granularity were chalcopyrite CuInSe2. The grown crystallites had tetrahedral shapes and homogeneous composition. Particle size distribution was used to describe the growth process. The activation energy of linear growth of crystals was E-d =0.25 +/- 0.05 eV, and the power of time dependence of the crystal growth was l/n-0.26 +/- 0.06. The solubility of CuInSe2 in KI at 990 K was 0. 17 +/- 0.05 wt. %. The solubility of potassium and iodine in CuInSe2 at 990 K was 0.094 wt. %, and 0.0086 wt. %, respectively. As a result, homogeneous p-type CuInSe2 monograin materials were synthesised in KI solvent. (C) 2007 Elsevier B.V. All rights reserved.
