Abstract:

Organic photovoltaic cells(OPVs) have the advantage of being colorful, light weight and flexible, and have great application prospects in the field of transparent, wearable, and stretchable electronics. In this review, the manipulation strategies of mechanical properties are reviewed for high efficiency OPVs active layer films, and the prediction models of their mechanical properties are summarized. First, the mechanical properties of the OPV films and their testing methods are briefly introduced. Then, the manipulation methods and prediction models of the mechanical properties of OPV films, including polymer∶nonfullerene small molecule acceptor and all-polymer blends, are described with important examples. Finally, our insights into the future trend of this exciting direction are provided.
