Abstract

A photovoltaic device is disclosed. The photovoltaic device includes a substrate, an anode, a cathode, and a semiconducting bilayer. The bilayer is composed of a first continuous sublayer and a second continuous sublayer. The first sublayer includes a first polymorph of a metallophthalocyanine. The second sublayer includes a second polymorph of the same metallophthalocyanine. The complementary absorption profiles of the polymorphs result in a device having greater absorption and efficiency, improving performace of the photovoltaic device.
