ABSTRACT
A high-efficiency concentrator PV array with an aperture area of approximately 1 m2 and a geometrical concentration ratio of 120x was fabricated. An all-glass design was chosen because of big advantages for many reasons. Glass was used as a superstrate for the concentrating lenses and as backside and sidewalls of the module-housing. Additionally, a very short focal length of 75 mm made the modules extremely compact. In this paper the manufacturing of the module is described and first results are presented. Long-term outdoor tests are foreseen.
