Disclosed are methods for the surface cleaning and passivation of PV absorbers, such as CdTe substrates usable in solar cells, and devices made by such methods. In some embodiments, the method involves an anode layer ion source (ALIS) plasma discharge process to clean and oxidize a CdTe surface to produce a thin oxide layer between the CdTe layer and subsequent back contact layer(s).

Photovoltaic devices and method of manufacturing

A method of fabricating a nozzle that includes casting and curing a first material using a patterned nip roller to form a first microstructured pattern of discrete microstructures, deforming at least one of the discrete microstructures; replicating the first microstructured pattern, including the at least one deformed discrete microstructure, in a second material different than the first material to make a replicated structure comprising a plurality of blind holes formed in the second material, removing second material of the replicated structure to expose tops of microstructures in the first microstructured pattern, and removing the first material from the replicated structure, resulting in a nozzle having a plurality of through-holes in the second material and corresponding to the first microstructured pattern.

Method of making a nozzle

Material comprising sub-micrometer particles dispersed in a polymeric matrix. The materials are useful in article, for example, for numerous applications including display applications (e.g., liquid crystal displays (LCD), light emitting diode (LED) displays, or plasma displays); light extraction; electromagnetic interference (EMI) shielding, ophthalmic lenses; face shielding lenses or films; window films; antireflection for construction applications; and construction applications or traffic signs.

Nanostructured articles and methods to make the same

Superhydrophobic films and methods of making such films are disclosed. More particularly, superhydrophobic films having durable nanostructures with high contrast ratios and various methods of producing such films are disclosed.

Superhydrophobic films

A composite having (a) a substrate that has opposing first and second surfaces, the substrate being at least 90% transmissive in visible light and has less than 5% haze, (b) a nanostructured article including a matrix and a nanoscale dispersed phase and having a random nanostructured anisotropic surface; and (c) an optically clear adhesive disposed on the second surface of the substrate.

Antireflective articles and methods of making the same

A nanostructured article comprises a matrix and a nanoscale dispersed phase. The nanostructured article has a random nanostructured anisotropic surface.

Nanostructured articles and methods of making nanostructured articles

Lightguides, devices incorporating lightguides, processes for making lightguides, and tools used to make lightguides are described. A lightguide includes light extractors arranged in a plurality of regions on a surface of the lightguide. The orientation of light extractors in each region is arranged to enhance uniformity and brightness across a surface of the lightguide and to provide enhanced defect hiding. The efficiency of the light extractors is controlled by the angle of a given light extractor face with respect to a light source illuminating the light guide.

Light guides having enhanced light extraction

Antireflective films are described comprising a light transmissive substrate and a low refractive index layer disposed on the light transmissive substrate. The low refractive index layer comprises the reaction product of polymerizable resin composition comprising at least 20 wt-% fumed silica. In one embodiment, the polymerizable resin is ethylenically unsaturated. In a favored embodiment, the low refractive index layer increases in porosity from the light transmissive substrate interface to an opposing porous surface.

Antireflective film comprising large particle size fumed silica

Laser-personalizable security articles include a multi-layer security document and an optically transparent processing tape. The multi-layer security document includes an optically transparent cover layer, a composite image and an imagable layer adjacent to the cover layer. The first surface of the cover layer is at least partially a microstructured surface, where the microstructured surface forms microlenses or a lenticular surface. The composite image is made by a collection of complete or partial images viewed through the microstructured surface of the cover layer. The composite image is located on or within the second surface of the cover layer. The imagable layer is a laser. The optically transparent processing tape sufficiently wets out on the misconstructured surface to render the microstructured surface invisible to a writing laser.

Laser-personalizable security articles

Multilayer construction is disclosed. The multilayer construction includes a II-VI semiconductor layer and a SiNlayer disposed directly on the II-VI semiconductor layer.

Multilayer construction

Semiconductor light converting constructions are disclosed. The semiconductor light converting construction includes a first semiconductor layer for absorbing at least a portion of light at a first wavelength; a semiconductor potential well for converting at least a portion of the light absorbed at the first wavelength to light at a longer second wavelength; and a second semiconductor layer that is capable of absorbing at least a portion of light at the first wavelength. The first semiconductor layer has a maximum first index of refraction at the second wavelength. The second semiconductor layer has a second index of refraction at the second wavelength that is greater than the maximum first index of refraction.

Semiconductor light converting construction

Etched substrates, and particularly, light-absorbing etched substrates, and methods for making such substrates are described.
