Two indacenodithiophene (IDT)-based small-molecule analogues (IDBT and IDBT-Cl) are designed as donor materials for organic solar cells. Relative to the amorphous IDBT-Cl, the IDBT with strong crystallinity shows overall better photovoltaic performance when blended with a Y6 acceptor. The results demonstrate the great potential of IDT units in designing efficient small-molecule donors.
