Comparison of bimolecular charge carrier recombination in π-conjugated polymers and bulk-heterojunction solar cells

Journal Article


Abstract


  • By using Time-of-Flight technique we have measured charge carrier transport and recombination in the π-conjugated polymer regiorandom poly(3-hexylthiophene (RRaPHT) and in two types of bulk-heterojunction solar-cells, namely in a blend of regioregular poly(3-hexylthiophene) mixed with 1-(3-methoxycarbonyl)propyl-1-phenyl-[6, 6]-methanofullerene (RRPHT/PCBM) and in the blend of poly[2-methoxy-5-(3, 7-dimethyloctyloxy)-phenylene vinylene] mixed with PCBM (MDMO:PPV/PCBM). We found Langevin-type charge carrier recombination in pure RRaPHT and in the MDMO:PPV/PCBM blend, while greatly reduced bimolecular recombination (compared to Langevin-type) was observed in the RRPHT/PCBM solar cell. © 2007 Old City Publishing, Inc.
