Abstract:
Die Erfindung bezieht sich auf einen Photokatalysator mit einer Absorptionskante zwischen 400 und 700 nm, der zur Wasserspaltung einsetzbar ist. Auf diesem Weg kann auch der hochenergetische Teil des Sonnenspektrums besser ausgenutzt werden.
Abstract:
The semiconductor device comprises a semiconductor substrate (2), a transition layer (5) in or on the semiconductor substrate, the transition layer allowing propagation of incident radiation (7) according to a refractive index, and a photonic component (4) facing the transition layer. A surface (6) of the transition layer is structured such that the effective refractive index is gradually changed through the transition layer with changing distance from the photonic component.
Abstract:
An optical solar enhancer comprises a panel that has a top surface and a bottom surface and an imaginary central plane that extends between the top surface and the bottom surface. The panel includes a plurality of generally parallel features configured to variably increase radiant energy entering the top surface at an acute angle relative to the central plane such that the effect is strongest at lower angles (early morning and late day sun) and weakest at higher angles (mid-day sun) and then redirect the increased radiant energy through the bottom surface.
Abstract:
An optoelectronic module includes a cover substrate including a passive optical element, a base substrate including an optoelectronic device, and a spacer layer joining the cover substrate to the base substrate. The spacer layer includes multiple first spacer elements fixed to a surface of the cover substrate and multiple second spacer elements fixed to a surface of the base substrate, in which each first spacer element is joined to a corresponding second spacer element through an adhesive layer, and in which the cover substrate, base substrate, and spacer layer define an interior region of the module in which the optical element is aligned with the optoelectronic device.

Abstract:
Technologies are generally described for manufacturing an optical device by attaching a light-emitting element to an optical element through a resin. In various examples, a method is described, where a substrate is provided to have a through-hole at a position in the substrate where an optical element is to be mounted. A resin in liquid state may be injected into the through-hole in the substrate. Further, an optical element having a light-emitting portion may be mounted on the substrate such that a center of the light-emitting portion is self-aligned with a center of the through-hole due to a surface tension of the resin in liquid state. The resin may be cured such that the optical element is fixed to the substrate.
