Abstract

We report on the photovoltaic properties of efficient multilayer devices based on pentacene thin films as a function of light intensity. Light-induced effects are characterized by the refined equivalent circuit model which incorporates an additional shunt resistance and an additional diode whose properties are function of the light intensity. Relative effects of these intensity-dependent parameters as well as the route to further optimization are discussed.
