Fullerene-Grafted Graphene for Efficient Bulk Heterojunction Polymer Photovoltaic Devices
Abstract
A simple lithiation reaction was developed to covalently attach monosubstituted C60 onto graphene nanosheets. Detailed spectroscopic (e.g., Fourier transform infrared, Raman) analyses indicated that C60 molecules were covalently attached onto the graphene surface through monosubstitution. Transmission electron microscopic (TEM) observation revealed that these monosubstituted C60 moieties acted as nucleation centers to promote the formation of C60 aggregates of ∼5 nm in diameter on the graphene surface. The resultant C60-grafted graphene nanosheets were used as electron acceptors in poly(3-hexylthiophene)-based bulk heterojunction solar cells to significantly improve the electron transport, and hence the overall device performance, yielding a power conversion efficiency of ∼1.22%.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
