| Popis: | In this study, we analyze the degradation behavior of conventional polymeric solar cells (PSCs) under constant indoor light illumination. A LED lamp with a color temperature of 2700 K, was used for the indoor light illumination conditions. We compare the results obtained with encapsulated and non-encapsulated devices. The performance of the PTB7:PC70BM-based cell showed an initial maximum power conversion efficiency (PCE) of 12.0% under the luminance of 1000 lux and maximum power density (MPP) of 45.7 μW/cm2. The work describes the results of the measurements and analysis of the degradation process, performed by a current density – voltage (J–V) characteristic curve study under LED light. The analyzed performance parameters were PCE, short circuit current density (JSC), open-circuit voltage (VOC) and fill factor (FF). The PCE of encapsulated devices remained above 80% of the initial value after 624 h. |
