A photovoltaic device and related methods. The device has a structured material positioned between an electron collecting electrode and a hole collecting electrode. An electron transporting/hole blocking material is positioned between the electron collecting electrode and the structured material. In a specific embodiment, negatively charged carriers generated by optical absorption by the structured material are preferentially separated into the electron transporting/hole blocking material. In a specific embodiment, the structured material has an optical absorption coefficient of at least 10<SUP>3 </SUP>cm<SUP>-1 </SUP>for light comprised of wavelengths within the range of about 400 nm to about 700 nm.
