In the recent years, the development of new non-fullerene-based organic acceptor (NFA) materials have strongly contributed to increasing the efficiency of organic photovoltaics (OPV), going from an average efficiency of about 12% to over 18%. More often than not, these excellent and fundamental developments, in terms of efficiency, are not compatible with potential production applications as well as still having severe limitations in lifetime and stability in a practical context.
It is therefore essential to improve the intrinsic characteristics of the devices, such as organic semiconductor, adapting formulations or manipulation of the interlayers for a fully compatibility with a productive process like slot-die by roll-to-roll (R2R). In the other side it is equally fundamental to have a clear vision of their behavior with the extrinsic stability of the panels themselves, such as both physical and chemistry compatibility with adhesives and barrier properties maintaining reasonable compromise between costs, final application, and context.
In this talk we will analyze some fundamental points required by a real scale-up, practical problems in their applications and give an analysis on the motivation of why these materials still take time to be used commercially.
