The ease with which small-molecule donors crystallize during solution processing is directly linked to the need for solvent additives. Donor molecules that get trapped in disordered (H1) or liquid crystalline (T1) mesophases require additive processing to promote crystallization, phase separation, and efficient light harvesting. A donor material (X2) that crystallizes directly from solution yields additive-free solar cells with an efficiency of 7.6%. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Citation
