An effective strategy for controlling the morphology of high-performance non-fullerene polymer solar cells without post-treatment: employing bare rigid aryl rings as lever arms in new asymmetric benzodithiophene

Almost all high-performance non-fullerene polymer solar cells (NF-PSCs) require the optimization of the morphologies of active layers using additional complicated treatments, such as solvent additive processing and thermal annealing. There are still no guidelines currently available regarding contro...
