New developments in CIGS thin-film solar cell technology

Thin-film solar modules based on Cu(In,Ga)Se/sub 2/ (ClGS) are on the way to mass production. ZSW is operating a line for 0.3 m /spl times/ 0.3 m modules in which all process steps - from glass cleaning to module encapsulation - are being developed. Especially new materials and processes are transferred from cells to the module level. In Wuerth Solar´s production line for 0.7 m/sup 2/ modules, progress has been made with industrial processing and real products. The presentation will give an overview of the module technology. The focus is on the new developments for modules with areas < 0.1 m/sup 2/.
