With the new efficiency world record of 20.3 % related to an aperture area of 527 cm2, AVANCIS sets a new international benchmark as a leading manufacturer of premium thin-film modules. The externally certified efficiency for an encapsulated CIGS-based thin-film module with integrated series interconnection of the size 30 cm × 30 cm represents another milestone for CIGS technology and opens up further perspectives for the use of building-integrated photovoltaic systems in modern architecture and sustainable construction.
