Abstract

Organic photovoltaics (OPVs) as a promising alternative energy source have attracted tremendous attention in recent years. Although the power-conversion efficiency (PCE) has been boosted up to 15%, the poor stability of OPVs is a huge barrier in the commercialization. Hence, we propose a facile method to enhance both the thermal stability and the efficiency of OPVs simultaneously by designing the rigid scaffold electron-transporting layer (ETL). The PCE with this structure was enhanced by 11% compared with the normal planar ETL. More importantly, thermally stable OPVs at 120°C was achieved, which gives a potential solution to the practical application of OPVs.
