Mono-Ketone Modified C(60)s for Acceptor Materials in Organic Photovoltaic Cells
We designed and synthesized methanofullerene derivatives with several types of thiophenyl mono-ketone for application in organic photovoltaic cells (OPVCs) as new accepter materials. The various mono-ketones having thiophene rings were substituted onto fullerene through application of Hirch-Bingel reaction under mild condition to compete with donor materials especially P3HT [Poly(3-hexylthiophene)] for nano-networking bulk-heterojunction structure where efficient light-induced charge separation is enable by a large-area donor-acceptor interface. The newly synthesized methanofullerene derivatives were characterized through H-1-NMR and FAB Mass spectroscopy. The compounds were also applied in OPV cell devices with P3HT as a donor material and measured electrochemical the property and power conversion efficiency.
