NOVELTY - Photovoltaic device comprises a substrate (110), a first electrode upon the substrate, a first semiconducting layer (140) comprising a phthalocyanine, a second semiconducting layer (150) comprising a polythiophene and an electron acceptor, and a second electrode, where the first and second semiconducting layers are located between the first electrode and the second electrode, and the first semiconducting layer is located closer in distance to the first electrode than the second semiconducting layer.    USE - The photovoltaic device is useful for generating an electrical current upon exposure to wide spectrum light such as sunlight, and in organic solar cells.    ADVANTAGE - The photovoltaic device is capable of capturing light energy present in sunlight and generates greater amounts of electricity, and increases the power conversion efficiency of the device.
