Nanofibrillar self-organization of regioregular poly(3-hexylthiophene) and [6,6]-phenyl C(61)-butyric acid methyl ester by dip-coating: a simple method to obtain efficient bulk heterojunction solar cells.
In this paper the dip-coating technique has been investigated as a method for the production of regioregular poly(3-hexylthiophene) (RR-P3HT):[6,6]-phenyl C(61)-butyric acid methyl ester (PCBM)-based solar cells. We found that the utilization of the dip-coating technique for the RR-P3HT:PCBM system can facilitate its self-assembly into a nanofibrillar lamellar structure after evaporation of the solvent. The condition for the formation of the nanofibrillar structures leads to a power conversion efficiency of 3.6% by using only this approach without thermal treatment.
