Abstract

We report on the latest progress in the field of organic p-i-n tandem solar cells. The results of tandem solar cells with an efficiency of 9.8% are shown (certified by Fraunhofer ISE) with an active area of about 1.1 cm². These solar cells show a promising intrinsic stability: a relative reduction of 5.7% of its initial power conversion efficiency was measured when stored at 85°C for 2400 hours. Additionally, we present a small OPV module with an active area of 122cm² showing an efficiency of with 9%, and an excellent low light behavior. Furthermore, we present the latest results on optimized tandem solar cells showing a power conversion efficiency of 10.7 % (measured by SGS, accredited and independent testing facility, active area of 1.1cm²).
