Ong Synthesis and characterization of thieno[3,2-b]thiophene-isoindigo-based copolymers as electron donor and hole transport materials for bulk-heterojunction polymer solar cells Journal of Polymer Science Part A: Polymer Chemistry 51
A series of thieno[3,2-b]thiophene and isoindigo-based polymers with D–π–A backbones have been synthesized. Their optoelectronic properties were tuned and optimized by using D−π−A conjugated main chains. Efficient bulk-heterojunction polymer solar cells were fabricated using these electron donor and hole transport materials.
