CIGS module manufacturing with high deposition rates and efficiencies

In this paper we present results of efficiency optimizations in conjunction with increased CIGS deposition rates. Furthermore, we describe Solibro´s recent technology improvements for higher module efficiencies and our roadmap for further efficiency improvements. Our results indicate that with co-evaporation of CIGS absorbers high module efficiencies can be realized at high dynamic deposition rates. Various improvements have recently been introduced in Solibro´s CIGS production process, which led to a champion module efficiency of 14.4% (total area, externally confirmed). Solibro´s efficiency roadmap shows that the technology is capable of producing average efficiencies of 17% within the next 3 years.
