Effects of dihydronaphthyl-based [60]fullerene bisadduct regioisomers on polymer solar cell performance.
The effects of fullerene bisadduct regioisomers on solar cell performance have been examined for the first time and the two substituent positions on C(60) have been found to have a large impact on the solar cell performance.
متن کاملOne-pot selective synthesis of a fullerene bisadduct for organic solar cell applications.
A single isomer of fullerene bisadduct, PC61PF, was obtained from commercially available fullerene derivative, PC61BM, in one pot over two steps. The tether-directed remote functionalization approach provided a very simple and fast method to produce a single isomer of fullerene bisadduct with good yield and easy purification. Bulk heterojunction organic solar cells containing the bisadduct was ...
متن کاملReducing regioisomers of fullerene-bisadducts by tether-directed remote functionalization: investigation of electronically and sterically isomeric effects on bulk-heterojunction solar cells.
C60 bis-adduct containing a mixture of regio-isomers with different LUMO energy levels and steric geometries could greatly affect the morphological and bulk properties. To investigate the regio-isomer effect on solar cell performance, we have successfully designed and synthesized a regio-selective 4-acetatephenyl-4'-methylphenylmethano C60 bis-adduct (S-APM-CBA) by "tether-directed remote funct...
متن کاملFullerene-containing liquid-crystalline dendrimers{
Addition reaction of mesomorphic malonate-based dendrimers (up to the fourth generation) with C60 gave liquid-crystalline fullerene derivatives. The cyanobiphenyl unit was used as liquid-crystalline promoter. The malonates presented nematic and/or smectic A phases. The fullerenes showed only smectic A phases, with the exception of the second generation dendrimer for which smectic A and nematic ...
متن کاملMolecular packing and solar cell performance in blends of polymers with a bisadduct fullerene.
We compare the solar cell performance of several polymers with the conventional electron acceptor phenyl-C61-butyric acid methyl ester (PCBM) to fullerenes with one to three indene adducts. We find that the multiadduct fullerenes with lower electron affinity improve the efficiency of the solar cells only when they do not intercalate between the polymer side chains. When they intercalate between...
