Amphiphilic Diblock Copolymer Compatibilizers and Their Effect on the Morphology and Performance of Polythiophene:Fullerene Solar Cells

A diblock copolymer containing a fullerene (C60) -rich block and a poly (3-hexylthiophene) block functions as a compatibilizer in poly (3-hexylthiophene): 6, 6-phenyl C61-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.
