    摘要: A photovoltaic module having a light transmissive front layer, a back layer, and a plurality of interconnected photovoltaic cells disposed between the light transmissive front layer and the back layer has a CTE-modified composite encapsulant is interposed between the plurality of solar cells and the light transmissive front layer. The composite encapsulant includes a bulk encapsulant transmissive to visible and near visible wavelengths of the solar spectrum and having a base coefficient of thermal (CTE) expansion, and an encapsulant CTE modifier in the bulk encapsulant. The encapsulant CTE modifier is substantially evenly distributed through the composite encapsulant thickness and interacts with the bulk encapsulant to reduce the effective CTE of the composite encapsulant below that of the bulk encapsulant.
