A new material for organic solar cell research
Chemical modification of lithium ion-encapsulated fullerene
Graduate School of Science
Fullerene (C60), a cage molecule shaped like a soccer ball, has attracted much interest because of its potential application to next-generation solar cells, organic thin-film photovoltaic devices. Prof. Yutaka Matsuo and Dr. Hiroshi Okada in the University of Tokyo’s Graduate School of Science, succeeded for the first time in the chemical functionalization of a lithium ion-encapsulated fullerene, and developed a novel organic electronic material, lithium-ion-encapsulated PCBM (PCBM is a fullerene derivative, [6,6]-phenyl-C61-butyric acid methyl ester, a standard fullerene derivative used in organic solar cells). This new compound has a high electron-accepting property, and is expected to be utilized in research for high-performance organic solar cells.
