Abstract: A photo-active device is provided that has a cavity in an integrated, transparent mold material. An active material layer is disposed therein along with other layers disposed in and about said cavity to define a dome-like array architecture. A process for forming the dome-like array structure includes disposing an active layer into a series of empty periodically positioned cavities of a dome-like array template working mold material. Each of the series of empty periodically positioned cavities has curvature variations of the interior surface of the dome-array cavities optimized for device efficiency, reduction of performance sensitivity to light impingement angle, or a combination thereof. At least one of absorber layers, contact layers, spacer/transport layers, and electrode layers are also disposed in the series of cavities.

Abstract: Lateral collection photovoltaic (LCP) structures based on micro- and nano-collecting elements are used to collect photogenerated carriers. In one set of embodiments, the collecting elements are arrayed on a conducting substrate. In certain versions, the collecting elements are substantially perpendicular to the conductor. In another set of embodiments, the micro- or nano-scale collecting elements do not have direct physical and electrical contact to any conducting substrate. In one version, both anode and cathode electrodes are laterally arrayed. In another version, the collecting elements of one electrode are a composite wherein a conductor is separated by an insulator, which is part of each collector element, from the opposing electrode residing on the substrate. In still another version, the collection of one electrode structure is a composite containing both the anode and the cathode collecting elements for collection. An active material is positioned among the collector elements.

Abstract: A process for forming a nano-element structure is provided that includes contacting a template with a material to form the nano-element structure having an array of nano-elements and a base physically connecting the array of nano-elements. The material that is contacted with the template is the nano-element structure material or precursor material from which the array of nano-elements is formed. The nano-element structure is then removed from contact with the template. The nano-element structure material or its precursor is brought into contact with the template for the forming of the array of nano-elements by techniques such as nano -imprinting and printing. A final substrate subsequently supports the array of nano-elements so produced. The array of nano-elements is exposed free and at least one layer of a dopant layer, a spacer layer, a light absorber layer, a conductor, or a counter electrode layer, are employed to complete an operative device.

Abstract: A photovoltaic device is provided that includes a periodic array having a unit cell with a first electrode protrusion of a height H, characteristic width W, and period L. An absorber of nominal thickness T has a volume with a first component between the electrode element protrusions and a second component completely covering the electrode protrusions,.

Abstract: Lateral collection photovoltaic (LCP) structures based on micro- and nano-collecting elements are used to collect photogenerated carriers, wherein the position of the collecting elements is determined by pattern transfer of an alternating depth trench pattern into a material to undergo solid phase crystallization: one depth corresponds to the elements of an electrode and the other depth corresponds to the elements of the counter-electrode. At least one of the metal electrode collecting elements can serve to enhance solid phase crystallization of the surrounding material in which the trenches were formed.
