Abstract: The development of nonfullerene acceptors (NFAs) has led to dramatic improvements in the device efficiencies of organic photovoltaic (OPV) cells. To date it is, however, still unclear how those laboratory‐scale efficiencies transfer to commercial modules, and how stable these devices will be when processed via industrially compatible methods. Herein, the degradation behavior of lab‐scale and scalable OPV devices using similar nonfullerene‐based active layers is assessed. It is demonstrated that the scalable NF… Show more

“…In a recent work from Madsen group, stability tests with different ISOS protocols are compared, [ 266 ] namely, ISOS‐L‐2 and ISOS‐O‐1. The former (lab weathering) is typically employed in lab‐scale experiments to elucidate photostability of promising high‐efficiency blends in controlled temperature and illumination conditions, while the latter (outdoor) is mainly useful to assess robustness of large area devices suitable for scalable applications even without impressive PCE.…”

“…These factors are responsible for two significant decay trends of PCE: burn-in and linear degradation. [30][31][32] For burn-in, the performance drop is relatively quick and is usually where the largest decrease in performance occurs, however, the impact of this degradation decreases as time progresses. [32][33][34] After the burn-in, a linear degradation occurs, resulting in a relatively low rate of decay in PCE.…”
