AVANCIS, leading manufacturer of premium class CIGS solar modules, enhances its own efficiency world record for thin-film solar modules. The new international standard is achieved with an externally certified power conversion efficiency of 19.8 % for an encapsulated thin-film module with integrated serial connection of size 30 cm x 30 cm. The efficiency world record related to the aperture area of 665 cm² was independently certified by the National Renewable Energy Lab (NREL). Thereby, the previous best value of 19.6 % could be further extended.
