Abstract :
International Solar Electric Technology (ISET) has developed a two-stage process for the deposition of stoichiometric and uniform CIS films. The conversion efficiencies of ISET´s CIS-based solar cells are about 11%. The two-stage process is briefly discussed, and the key issues that need to be addressed in order to make this technique suitable for large-scale, low-cost manufacturing of CIS modules are highlighted. Estimates for cost of manufacturing for a plant with a production capacity of 6 MW/yr (on one shift per day basis) shows that CIS modules can be manufactured for <US $1.00/W
