under standard test conditions (25 C and an illumination of AM1.5spectrum and 100mWcm2). The measured short-circuit currentdensity (J SC) in the IV measurement is consistent to the J SCcalculated from the spectral response measurement also performedat the Fraunhofer ISE. The IV measurement was performed withboth sweep directions (J SC to open circuit voltage (VOC), VOCto J SC) to take the mean value and there was no hysteresisobserved (
