Findings from Pusan National University in Aromatic Polycyclic Hydrocarbons Reported (Synthesis and Characterization of Phenanthrene-substituted Fullerene Derivatives as Electron Acceptors for P3HT-based Polymer Solar Cells)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Fresh data on Aromatic Polycyclic Hydrocarbons are presented in a new report. According to news originating from Pusan, South Korea, by VerticalNews correspondents, research stated, "9,10-Bis(bromomethyl)phenanthrene reacted with fullerenes via a Diels-Alder reaction to give phenanthrene-substituted fullerene mono-adducts (PCMA) and bis-adducts (PCBA) as electron acceptors for organic photovoltaic cells (OPVs). The syntheses of the fullerene derivatives were confirmed by H-1 C-13 NMR spectroscopy and MALDI-TOF mass spectrometry."

Our news journalists obtained a quote from the research from Pusan National University, "PCMA and PCBA showed better light absorption in the UV-visible region than PC61BM. Their electrochemical properties were measured using cyclic voltammetry. Accordingly, the lowest unoccupied molecular orbital (LUMO) energy levels of PCMA and PCBA were -3.66 and -3.57 eV, respectively. Photovoltaic cells were fabricated with a ITO/PEDOT:PSS/poly(3-hexylthiophene)(P3HT):acceptor/LiF7Al configuration, where P3HT and PCBA are the electron donors and acceptors, respectively."

According to the news editors, the research concluded: "The polymer solar cell fabricated using the P3HT:PCBA active layer showed a maximum power conversion efficiency of 0.71%."
