DOI: 10.1016/j.orgel.2017.04.030

Abstract: The non-geminate recombination was investigated in TQ1:PC61BM:PC71BM (poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl]:[6,6]-Phenyl-C61-butyric-acid-methyl-ester:[6,6]-Phenyl-C71-butyric-acid-methyl-ester) bulk heterojunctions employing the extraction of the photogenerated charge carriers by linearly increasing voltage (photo-CELIV) and integral Time-of-Flight (ToF) techniques. The shapes of photo-CELIV and ToF transients… read more here.

DOI: 10.1021/acsami.8b22073

Abstract: Size-selected graphene oxide (GO) nanosheets were used to modify the bulk heterojunction (BHJ) morphology and electrical properties of organic photovoltaic (OPV) devices. The GO nanosheets were prepared with sizes ranging from several hundreds of nanometers… read more here.

DOI: 10.1038/s41467-018-04502-3

Abstract: Nonfullerene solar cells have increased their efficiencies up to 13%, yet quantum efficiencies are still limited to 80%. Here we report efficient nonfullerene solar cells with quantum efficiencies approaching unity. This is achieved with overlapping… read more here.
