Facile Solubilization and Photovoltaic Application of C60 Fullerene–Ethylenediamine Adduct

Abstract

Abstract Fullerene C60–ethylenediamine adduct particles were solubilized in toluene by the addition of acyl chloride. An inverted-type bulk-heterojunction organic thin-film solar cell using polythiophene and the solubilized C60–ethylenediamine adduct as the photoactive layer was fabricated, and the layer generated a photocurrent via the photoexcitation of polythiophene. The solar-cell performance suggested that the solubilized C60–ethylenediamine adduct works as an n-type semiconductor for polythiophene.
