Material solubility effects in bulk heterojunction solar cells based on the bis-cyclopropane fullerene adducts and P3HT

Research in the Field of Organic Photovoltaics at the Institute for Problems of Chemical Physics of Russian Academy of Sciences

“…Few other examples proving that supramolecular assembling of different fullerene derivatives and conjugated polymers in the blends is governed by the relative solubility of the materials were reported recently [106][107][108][109][110][111]. It should be emphasized that varying the solvents, applying thermal or solvent vapor annealing, using processing additives and playing with other film processing conditions alter mainly the kinetics of the blend formation.…”

Benzocyclobutene-fullerene bisadducts as novel electron acceptors for enhancing open-circuit voltage in polymer solar cells

“…OXCBA also has a LUMO energy level that is approximately 0.2 eV higher than that of PCBM, which resulted in significantly enhanced PCEs. And other fullerene bisadduct derivatives have been developed as alternative acceptor materials [21][22][23][24][25][26][27][28]. However, despite the great potential of fullerene bisadducts to enhance the V OC values in PSCs, their success has been limited mainly to the polythiophene analogs based PSC systems, partly because of the significant reduction of the electron transport ability through the fullerene phases which results from the presence of their regioisomers [7,[29][30][31][32].…”

Spectral Investigations of Hybrid Nanostructures Including Modified Fullerene C60 and Carbazole-Derivative Fluorophore

“…Carbon nanomaterials (carbon nanotubes, graphene, fullerenes) have unique electronic and mechanical properties and are widely applied for a creation of novel composite materials [4]- [6], electronic functional components [7] [8], etc. Fullerenes having very interesting properties due to unique electronic structure can be widely used for application in a construction of the hybrid nanostructures.…”
