NOVELTY - A solar electric module (110) comprises a transparent front cover; solar cells (36); a back cover; a light transmitting encapsulant disposed between front cover and back cover; and a light redirection layer disposed between solar cell and back cover and having several perforations of a predetermined size in regions obscured by solar cells. The perforations provide moisture transport into and out from light transmitting encapsulant. The light transmitting layer contains a weight mitigation layer disposed between back surface of front cover and encapsulant.    USE - For large commercial flat roof installations for converting solar energy into electrical energy.    ADVANTAGE - The weight mitigation layers reduce the volume of glass in top cover, while providing an increased distance between light redirection layer and top cover. The increased distance supports increased spacing between solar cells. The solar electric module enables simpler manufacturing procedures and raises market acceptance of modules for large commercial flat roof installations, where the total weight of the modules can be excessive. The module uses reflector materials to reduce module costs by reducing the number of solar cells used to as few as one-half to one-third of those used in conventional modules without a light reflector feature. The module reduces the weight of a module while retaining cost benefits arising from a light reflecting material, thus increasing the market penetration window for the low concentrator general class of light reflector solar products. The module has a reduced weight compared to existing solar electric modules. The weight mitigation layer retains the advantages of a glass cover (for transparency, resistance to degradation, protection of the front of the module, moisture impermeability that does not transmit water, and hardness (scratch resistance)) while limiting the thickness (and weight) of the transparent front panel. The use of the weight mitigation layer increases the reflecting layer distance, which, in turn allows the solar cells to be space farther apart. As a result, a solar electric module can provide about the same power output with fewer solar cells compared to a solar electric module without any weight mitigation layer. The weight mitigation layer also provides the unexpected result of increased reliability, because there are fewer solar cells. The weight mitigation layer also provides the unplanned and fruitful result of providing more ultraviolet (UV) protection to components (for example, reflecting layer) below the weight mitigation layer, because increased polymer layer typically has UV blocking or absorbing properties.    DETAILED DESCRIPTION - A solar electric module (110) comprises a transparent front cover having a front surface and a back surface; several solar cells (36) configured in a substantially coplanar arrangement and spaced apart from each other; a back cover spaced apart from and parallel to front cover; a light transmitting encapsulant disposed between front cover and back cover; and a light redirection layer disposed between solar cell and back cover. The solar cells are disposed between transparent front cover and back cover. The solar cells has front surfaces facing transparent front cover and back surfaces facing away from the transparent front cover. Each solar cell has one front surface and one back surface. The transparent front cover transmits light through transparent front cover and incident on light redirection layer in regions between solar cells. The light redirection layer directs light towards transparent front cover. The front surface of transparent front cover internally reflects light back towards the front surfaces of solar cells. The light redirection layer has several perforations of a predetermined size at least in regions obscured by solar cells. The perforations provide moisture transport into and out from light transmitting encapsulant. The light transmitting layer contains a first layer of transparent material containing at least one encapsulant sheet, and a weight mitigation layer disposed between back surface of transparent front cover and encapsulating sheet. The weight mitigation layer has a density less than transparent front cover, and replaces a volume of the transparent front cover equal to a volume of the weight mitigation layer. The light redirection layer is an asymmetric redirection layer containing a light scattering film (132) and a light reflective layer. The light reflective layer comprises perforations.
