In article no. 1900063 , Kai Wang and co‐workers report the spin‐dependent electron‐hole recombination and dissociation in nonfullerene acceptor ITIC‐based binary and ternary organic bulk heterojunction systems. ITIC itself exhibits a negative magneto‐photocurrent due to the exciton‐charge reaction. The effect becomes critically important for electron‐hole dissociation in both systems at large fields and longer photo‐excitation wavelengths.
