Molecular interaction induced dual fibrils towards organic solar cells with certified efficiency over 20%

Molecular interaction induced dual fibrils towards organic solar cells with certified efficiency over 20% The nanoscale fibrillar morphology, featuring long-range structural order, provides abundant interfaces for efficient exciton dissociation and high-quality pathways for effective charge transport, is a promising morphology for high performance organic solar cells. Here, we synthesize a thiophene terminated non-fullerene acceptor, L8-ThCl, to induce the fibrillization of both polymer donor a...
