Thin-film solar modules based on CIGS absorber are an emerging technology in Europe. To accelerate the acceptance of the product on the marketplace aesthetically convincing solutions for building integration combined with high technical quality are required. The aim of the present work is to develop high performance, high quality and stable thin-film PV modules for the integration into buildings (facades and roofs) forming a fully integrated part of the outer building skin. Technologies used in structural glazing and other facade building technologies were adapted for framing and fastening elements of the facade modules. Encapsulation alternatives for modules with high reliability and long-term stability have been evaluated and are under testing. A detailed electrochemical investigation of the corrosion mechanisms of constituents of the cell structure was started to corroborate the empirical data on module stability and to provide suggestions for further improvements. International and national building standards have been compiled. Technical requirements and design rules have been derived. Concepts for facade integration including mechanical fixing technology and electrical interconnection have been worked out. A first lab model of a SUNSLATES(TM) with CIGS solar module was realized.
