Self-assembly of carboxylated polythiophene nanowires for improved bulk heterojunction morphology in polymer solar cells
2012
Journal of Materials Chemistry
Conjugated regioregular poly[3-(5-carboxypentyl) thiophene-2,5-diyl] (P3CPenT), a derivative of poly(3-hexylthiophene) (P3HT), is introduced as a hole transport layer (HTL) for P3HT:PCBM plastic solar cells (PSCs). P3CPenT, a carboxyl-functionalized polythiophene, is insoluble in solvents typically used in the preparation of photoactive layers such as chloroform, chlorobenzene and dichlorobenzene, allowing successive processing of the photoactive layer without dissolution of the HTL.
