✦ Synopsis

The reaction kinetics of copper indium diselenide formation is studied by measuring species composition as a function of time at 2508 8 8C and 3258 8 8C in a tubular chemical vapor deposition reactor. This extends our previous modeling and experimental study at 4008 8 8C. The initial copper±indium alloy is analyzed at the reaction temperatures using high-temperature X-ray diraction measurements. This modi®es the understanding of the chemistry of the copper indium growth kinetics and a new set of model equations is presented. The speci®c reaction rate constants and activation energies for the chemical reactions are obtained, enabling one to calculate the holding time for the reaction.
