Popis: |
In this study, we analyze the stability and degradation of inverted organic solar cells (iOSCs) partially fabricated under air environment. It is compared the degradation of iOSCs manufactured with PFN against inkjet printed ZnO as electron transport layer (ETL). The active layer use PTB7 and PC70BM as donor and acceptor material, respectively for all devices. The electrical parameters during the degradation process were extracted from the current density - voltage characteristics (J-V) under light and dark conditions. The power conversion efficiency (PCE) of the devices under nitrogen without encapsulation decreased down to 80% after 58 h for iOSCs with PFN and after 189 h for inkjet printer ZnO. Photovoltaic devices under air and without encapsulation manufactured with ZnO, the PCE decrease to 80 % after 160 h. |
