1. A photovoltaic device comprising:
1) a three-dimensional multi-layered photovoltaic cell assembly in the form of a panel with at least a top surface, a bottom surface, and a peripheral edge and the three-dimensional multi-layered photovoltaic cell assembly comprising:
a top layer,a photovoltaic cell assembly,a first encapsulant layer between the top layer and a top of the photovoltaic cell assembly,a back sheet,a second encapsulant layer between the back sheet and a bottom of the photovoltaic cell assembly, anda supplemental barrier layer located on an opposite side of the back sheet as the second encapsulant layer, wherein the three-dimensional multi-layer includes:a cell elastic modulus value,a cell ultimate elongation value,a cell coefficient of thermal expansion value, anda cell yield strength value; 2) a body portion assembly including:
a body portion elastic modulus value,a body portion ultimate elongation value,a body portion coefficient of thermal expansion value, anda body portion yield strength value,wherein the body portion assembly is at least partially surrounding a portion of the top surface and peripheral edge of the three-dimensional multi-layered photovoltaic cell assembly; and 3) an intermediate layer comprised of a layer material and including:
a layer elastic modulus value,a layer ultimate elongation value,a layer coefficient of thermal expansion value, anda layer strength value,wherein there is a gap between the top layer of the three-dimensional multi-layered photovoltaic cell assembly and the body portion and the intermediate layer is at least partially disposed in the gap, andwherein the layer elastic modulus value is at least 5 percent less than the body portion elastic modulus value or the cell elastic modulus value. |
