A multi-color dielectric coating is formed using interleaved layers of dielectric material, having alternating refractive index, to create reflections at selected wavelengths, thus appearing as different colors. Etching of selected layers at selected locations changes the color appearance of the etched locations, thus generating a coating having multiple colors. The thicknesses of the layers are chosen such that the path-length differences for reflections from different high-index layers are integer multiples of the wavelength for which the coating is designed.

Multi-colored dielectric coating

An optical coating, such as anti-reflective coating (ARC) or colored coating for optical devices, suitable especially for mobile devices. The ARC is made up of alternating layers of low refractive index and high refractive index. At least one of the layers, preferably the top layer, is made up of nano-laminate. The nano-laminate is a structure of alternating nano-layers, each nano-layer made out of a material having refractive index similar to the layer it replaces. Optionally, each of the layers are made up of nano-laminates, such that a layer having low refractive index is made up of nano-laminates of nano-layers having low refractive index, while high index layers are made up of nano-lamonate of nano-layers having high refractive index. Each of the nano-layers is of 2-10 nanometer thickness.

Lithium-iron molecular precursor compounds, compositions and processes for making a cathode for lithium ion batteries. The molecular precursor compounds are soluble and provide processes to make stoichiometric cathode materials with solution-based processes. The cathode material can be, for example, a lithium iron oxide, a lithium iron phosphate, or a lithium iron silicate. Cathodes can be made as bulk material in a solid form or in solution, or in various forms including thin films.

Molecular precursors for lithium-iron-containing cathode materials

Processes for making a solar cell by depositing various layers of components on a substrate and converting the components into a thin film photovoltaic absorber material. Processes of this disclosure can be used to control the stoichiometry of metal atoms in making a solar cell for targeting a particular concentration and providing a gradient of metal atom concentration. A selenium layer can be used in annealing a thin film photovoltaic absorber material.

Annealing processes for photovoltaics

Processes for making a thin film solar cell on a substrate by providing a substrate coated with an electrical contact layer, depositing an ink onto the contact layer of the substrate, wherein the ink contains an alkali ion source compound suspended or dissolved in a carrier along with photovoltaic absorber precursor compounds, and heating the substrate. The alkali ion source compound can be MM(ER)or M(ER). The processes can be used for CIS or CIGS.
