Abstract

Described herein are organic photovoltaic (OPV) cells using gold complex(es) with as chemical structure of Structure I as active material:wherein, wherein R1-R15 are independently hydrogen, halogen, hydroxyl, an unsubstituted alkyl, a substituted alkyl, cycloalkyl, an unsubstituted aryl, a substituted aryl, acyl, alkoxy, acyloxy, amino, alkylamino, nitro, acylamino, aralkyl, cyano, carboxyl, thio, styryl, aminocarbonyl, carbamoyl, aryloxycarbonyl, phenoxycarbonyl, hydroxyalkyl, or an alkoxycarbonyl group. The OPV cell can be fabricated by thermal deposition or solution process such as spin coat and printing.
