Amphiphilic diblock copolymer compatibilizers and their effect on the morphology and performance of polythiophene:: Fullerene solar cells

A diblock copolymer containing a fullerene(C-60)-rich block an a poly(3-hexylthiophene) block functions as a compatibilizer in poly (3-hexylthiophene):[6,6]-phenyl C-61-butyric acid methyl ester (P3HT:PCBM) blends. The copolymer is used to probe the impact of morphology and phase-segregation kinetics on the performance of P3HT:PCBM-based solar cells.
