摘要： The area of Concentrating Solar Power (CSP) and Concentrating Photovoltaics (CPV) require reliable, robust and durable reflectors capable of withstanding different environments, weather and transportation conditions. It is therefore important to use a method for fabricating a reflector which seals a reflector edge against moisture, corrosion and contaminants and protects the edge from cracks and damage. Embodiments of this method include depositing a clear sealant over the reflector edges, extending a reflective film over the edges of the reflector then sealing from the back and laminating a flexible strip of a clear polymer such as PVB and EVA around the top edge, a bottom edge, and all side edges of the reflector. Another embodiment includes performing hemming process on a front assembly of the reflector over the edges of a back assembly forming a sacrificial layer at the back of the reflector to prevent delamination.
