Abstract
A nanostructured or microstructured array of elements on a conductor layer together form a device electrode of a photovoltaic or detector structure. The array on the conductor layer has a high surface area to volume ratio configuration defining a void matrix between elements. An active layer or active layer precursors is disposed into the void matrix as a liquid to form a thickness coverage giving an interface on which a counter-electrode is positioned parallel to the conduction layer or as a vapor to form a conformal thickness coverage of the array and conduction layer. The thickness coverage is controlled to enhance collection of at least one of electrons and holes arising from photogeneration, or excitons arising from photogeneration, to the device electrode or a device counter-electrode as well as light absorption in said active layer via reflection and light trapping of said device electrode.
