Abstract

A critical assessment of the thermochemical and phase diagram data for the CuInSe system has been initiated. This report includes assessment of the Se unary, InSe binary and CuSe binary systems. Based on these assessments and a previously published assessment (Kao et. al, 1993) for the CuIn system, a preliminary evaluation of the the Cu₂SeIn₂Se₃ pseudobinary phase diagram is proposed. The results of these analyses were applied to the calculation of the flux from a selenium effusion cell used for depositing CIS films and to the prediction of crystallization pathways during annealing of CIS precursor films
