文摘
- •
Three novel polymers have branched side chains with varied branching positions.
- •
The bifurcation positions influnce intermolecular stacking and film morphology.
- •
The bifurcation positions influnce charge mobility and photovoltaic performance.
- •
The best PCE of 5.67% is achieved by adjusting the bifurcation points position.
