Abstract

A photovoltaic device is disclosed. The photovoltaic device includes a substrate, an anode, a cathode, two semiconducting layers, and an electron transporting layer. The first semiconducting layer comprises a first metallophthalocyanine. The second semiconducting layer includes a blend of a second metallophthalocyanine with an electron acceptor. The second semiconducting layer is located between the first semiconducting layer and the electron transporting layer. The first and second metallophthalocyanines have different valences. The complementary absorption profiles of these layers result in a device having greater absorption and efficiency than expected, without the need for a recombination layer or the need to match current between layers.
