Analysis of the stability of organic photovoltaic cells under indoor illumination

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 2700 K, was used for illumination conditions. We compare results obtained encapsulated and non-encapsulated devices. The performance PTB7:PC70BM-based cell showed an initial maximum power conversion efficiency (PCE) 12.0% luminance 1000 lux density (MPP) 45.7 μW/cm2. work describes measurements analysis process, performed by current – voltage (J–V) characteristic curve study light. analyzed parameters were PCE, short circuit (JSC), open-circuit (VOC) fill factor (FF). PCE devices remained above 80% value after 624 h.
