Evolution of interfacial defects and energy losses during aging of organic photovoltaics

Evolution of interfacial defects and energy losses during aging of organic photovoltaics

As the power conversion efficiencies of Organic Solar Cells (OSCs) approach 20 %, the stability of the device becomes an increasingly urgent issue. To enhance device stability, it is crucial to identify potential loss mechanisms. In this study, we investigated the trap-state-dependent degradation me...
