Random terpolymer based on thiophene-thiazolothiazole unit enabling efficient non-fullerene organic solar cells
Abstract
The batch reproducibility of polymer donor materials limits the performance of polymer solar cells. Here Wu et al. develop a polymer donor PM1 by random terpolymerization strategy with a high efficiency of 17.6% in the device and excellent batch-to-batch reproducibility.
