ABSTRACT
A new module assembly concept has been developed, based on quasi endless, flexible solar cells. The solar cells are fabricated in a base line by the CISCuT technology. It consists of a sequence of five distinct roll-to-roll batch processes. Within the module assembly, solar cell stripes are interconnected in series to strings by the so-called,,roof-tile" principle. Any number of strings then can be interconnected in parallel by bus bars. Finally, the absorber is encapsulated in a stack of polymer foils. An assembly line has been developed, integrating these steps in an automated continuous process in order to realise a full base line for module manufacturing. The technology allows fabrication of flexible modules, adaptable in voltage, current and power output as well as in shape and size. Thus, the module fits easily to different applications.
