Abstract
Two novel oligomers boost the 1 cm 2 device to achieve a remarkable PCE exceeding 17% using a green solvent in open-air without post-treatment. In-depth in situ & ex situ studies elucidate the mechanisms of action of the oligomers. This work demonstrates effective guidelines for future manufacturing.
