Description
Summary:Electrodeposition based CIGS technology developed by SoloPower is highly attractive route for preparation of precursor layers due to its low cost, efficient materials utilization and scalability to high-volume manufacturing. Several aqueous electroplating solutions both in acidic and alkaline regimes are formulated and optimized for achieving stable plating solutions for roll-to-roll electrodeposition that give adherent and high quality films with controllable molar compositions. An optimized rapid thermal annealing approach was developed to achieve device-quality CIGS absorber layers. In this paper, we discuss various electrodeposition approaches for CIGS precursor formation and present a summary of the recent results for SoloPower's flexible cells.
