Deskripsi

Long operational stability is essential to commercialisation of organic solar cells. Here, the authors investigate the thermal degradation of inverted photovoltaic devices based on PM6:Y6 non-fullerene system to reveal that trap-induced transport resistance is primarily responsible for the drop in fill factor.
