Samenvatting:
For the first time, a certified AM1.5 efficiency of 8.2% has been reached for nano-crystalline dye-sensitized solar cells (nc-DSC) on areas larger 1 cm 2 ; i.e. 2.5 cm 2 . It has been further proven, that 2-valent salts like MgI2 and CaI2 as additives to the electrolyte have a strong stabilising effect during UV-illumination. Tests under continuos light soaking for several thousand hours demonstrate the ability of nc-DSCs to operate for at least 5 ? 10 years under outdoor illumination conditions without major degradations. Continuos and periodic thermal tests according to IEC 1215 norms are promising but with 30% to 40% loss in efficiency still critical.
