Title: Synergistic effects of chlorination and a fully two-dimensional side-chain design on molecular energy level modulation toward non-fullerene photovoltaics

Abstract

By taking the advantage of chlorination and fully conjugated side chains,2D-PBTClshows a PCE of up to 8.81% in non-fullerene solar cells, which corresponds to an approximately 28% improvement compared to that ofPTB7-Th-based devices.
