Reports from Osaka University Describe Recent Advances in Fullerenes (Exploring Photovoltaic Feasibility of Pentaaryl [60]Fullerene in Bulk Heterojunction Architecture)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Fresh data on Fullerenes are presented in a new report. According to news reporting originating in Osaka, Japan, by VerticalNews journalists, research stated, "The photochemical process of pentaaryl [60]fullerenes (PAC(60)) has been investigated by fluorescence and transient absorption spectroscopies, aiming at their use in bulk heterojunction organic photovoltaic (OPV). Fluorescence quenching was observed by adding C-60 into PAC(60), where the intensity was decreased in an exponential manner."

The news reporters obtained a quote from the research from Osaka University, "The photo-generated radical cation of PAC(60) was identified at 925 nm in the presence of electron acceptor. Motivated from the observed shallow molecular orbital levels of PAC(60), we performed conceptual study of all-fullerene OPV, where PAC(60) and [6,6]-phenyl-C-61-butyric acid methyl ester (PCBM) were presumably used as a p-type and n-type semiconductor, respectively. The power conversion efficiency was 0.007%, much smaller than 0.05% found for the conventional combination of P3HT (p-type) and PAC(60) (n-type)."

According to the news reporters, the research concluded: "The mechanism is discussed on the basis of photoconductive and spectroscopic results."
