Abstract: A method of making an optical film for control of light includes positioning a first mixture on a substrate, wherein the first mixture includes a first plurality of magnetizable particles dispersed in a first resin, assembling the first plurality of magnetizable particles into a desired structure for the control of the light by rotating modulation of at least a first magnetic field relative to the first plurality of magnetizable particles, and vitrifying the first resin while the first plurality of magnetizable particles are in the desired structure.

Abstract: According to one embodiment, a solar device, comprises one or more photovoltaic cells disposed in an encapsulant and a light control structure including a louver film having a series of louver structures, wherein each louver structure includes one or more groupings of a plurality magnetizable particles aligned at least in a first orientation dispersed in a binding matrix. The light control structure substantially transmits light incident at a first angle and substantially limits transmission of light incident at a second angle. Each louver structure is spaced apart from an adjacent louver structure, wherein each louver structure is substantially aligned in a plane substantially parallel to an adjacent louver structure.

Abstract: A light redirecting film defining a longitudinal axis, and including a base layer, an ordered arrangement of a plurality of microstructures, and a reflective layer. The microstructures project from the base layer, and each extends across the base layer to define a corresponding primary axis. The primary axis of at least one of the microstructures is oblique with respect to the longitudinal axis. The reflective layer is disposed over the microstructures opposite the base layer. When employed, for example, to cover portions of a PV module tabbing ribbon, or areas free of PV cells, the films of the present disclosure uniquely reflect incident light.

Abstract: A multilayer optical film including a stack of microlayers arranged into optical repeat units. At a design angle of incidence, such as normal incidence, the stack provides a 1st order reflection band, a 2nd order reflection band, and optionally a 3rd order reflection band. The 2nd order reflection band substantially overlaps the 1st and/or 3rd order reflection bands to form a single wide reflection band. The wide reflection band may cover at least a portion of visible and infrared wavelengths. The multilayer optical film may include an additional optical layer which maybe be an anti-glare layer and/or may be an absorbing layer. The multilayer optical film is suitable for use as a window film.

Abstract: The present disclosure generally relates to durable solar mirror films, methods of making durable solar mirror films, and constructions including durable solar mirror films. Some embodiments of the present disclosure relate to methods of making solar mirror films that do not include a reflective layer material across the entire weatherable layer. Some embodiments relate to a method of making a solar mirror film involving providing a weatherable layer having a first major surface and a second major surface; depositing a reflective material on the first major surface of the weatherable layer; and removing a portion of the reflective material (e.g., ultrasonically, mechanically, or thermally).
