Abstract

A novel bisazide molecule to be used in polymer–fullerene bulk heterojunction (BHJ) solar cells with two distinct functionalities is reported here. Firstly, it acts as a solvent-additive to reach optimized BHJ morphology and power conversion efficiencies without further requirements of annealing post-treatment of the active layer. Secondly, this molecule is a powerful thermally-triggered cross-linker for fullerenes enabling to freeze the BHJ morphology in its optimized form making active layers thermally stable.
