Abstract

A solar electric module having a layered construction including a light redirection layer and light transmitting materials that encapsulate the solar cells of the module. The solar electric module provides for weight mitigation and/or moisture control features. The weight mitigation feature provides for the use of weight mitigation layers to reduce the volume of glass in a transparent top cover, while providing an increased distance between the light redirection layer and the transparent top cover. The increased distance supports increased spacing between solar cells. The moisture control feature provides perforations in a metallic coating layer and/or light redirection layer to support migration of moisture into and out of the encapsulating layers. The light redirection layer can be an asymmetric redirection layer (for example, light scattering layer) or a symmetric redirection layer (for example, a diffractive optical element).
