Abstract
In one aspect of the present invention, a reflector for use in a solar collector will be described. The reflector includes a thin film reflective coating that is positioned on a layer. For example, the layer may be a substrate that physically supports the reflective coating or a protective layer. There are multiple spaced apart pinning regions that are distributed through an interface between the layer and the thin film reflective coating. The pinning regions locally anchor the reflective coating to the layer. Some aspects of the present invention relate to the use of pinning regions in other types of optical or electrical components.
