Preparation and Characterization of a Selective Polymer-Based Solar Absorber for Building Integration

Preparation and Characterization of a Selective Polymer-Based Solar Absorber for Building Integration

Recent technological advances in solar absorber production may have created opportunities for new applications of these materials in buildings. A low-emissivity enhanced polymer-based absorber foil was developed and prototyped to demonstrate feasibility of the concept. This paper describes key devel...
