Description:
As one of the promising emerging photovoltaic technologies(PVs), organic solar cells (OSCs) have received extensiveattention from both scientific and industry communities. Theadvantages of OSCs, such as low toxicity, high power-to-weight ratio, and easy manufacturing and upscaling, guar-antee their contribution to versatile applications powered byclean and renewable solar energy, for instance, applicationsrelying on flexibility, transparency, color management orintegrability. The progress in the field of OSCs is usuallydriven by the development of novel organic semiconductors,and effective material strategies are expected to accelerateorganic PV towards a gigawatt (GW) level, becoming animportantpartoftheglobalandsustainablePVscenarios[1].Therecentbreakthrough inthe fieldofOSCscomesfromthedevelopment of advanced non-fullerene acceptors (NFAs)[2]. Compared to the historically first acceptors, which arefullerenes and their derivatives, the optoelectronic propertiesof NFAs can be readily tailored to match state-of-the-artdonor materials in terms of complementary absorption, en-ergy levels, charge dissociation and collection. Among thenovel class of NFAs, Y6 in particular stands out. Y6 wasintroduced in 2019 with a power conversion efficiency(PCE) of over 15% [3]. Since then, the structure-propertyrelations of the Y6 family have been continuously improved,either by side chain engineering or processing variations,leading to PCE values of about 18% [4].
