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.
