Title
(EN) Photovoltaic module backboard and photovoltaic module comprising same
(ZH) 光伏组件背板及含其光伏组件
Abstract
(EN) The invention provides a photovoltaic module backboard and a photovoltaic module comprising the same. The photovoltaic module backboard comprises an insulating layer, a reflecting layer, a first decorative layer and a first transparent protective layer which are stacked in sequence, and matrix resin forming the reflecting layer and the first decorative layer is fluorine-containing resin. The matrix resin forming the reflecting layer is the same as the matrix resin forming the first decorative layer, so that the compatibility between the reflecting layer and the first decorative layer can be greatly improved, and the layering risk of the photovoltaic module backboard is reduced. The fluorine-containing resin has good weather resistance, chemical stability, flame retardance, low friction coefficient and the like, so that the fluorine-containing resin is selected as matrix resin of the reflecting layer and the first decorative layer, and meanwhile, the first transparent protective layer is arranged, so that the ultraviolet blocking rate, the weather resistance, the flame retardance, the attractiveness and the insulativity of the photovoltaic module are greatly improved. Because the pattern in the first decorative layer can fill the gap and the edge of the target photovoltaic module, the photovoltaic module backboard has good aesthetic property.
(ZH) 本发明提供了一种光伏组件背板及含其光伏组件。该光伏组件背板包括依次层叠设置的绝缘层、反射层和第一装饰层及第一透明保护层,形成反射层和第一装饰层的基体树脂为含氟树脂。形成反射层和第一装饰层的基体树脂相同能够大大提高反射层和第一装饰层之间的相容性,降低光伏组件背板的分层风险。含氟树脂具有良好的耐候性、化学稳定性、阻燃性能和低摩擦系数等性,因而选用含氟树脂作为反射层和第一装饰层的基体树脂,同时设置第一透明保护层有利于大大提高光伏组件的紫外线阻隔率、耐候性、阻燃性、美观性和绝缘性。由于第一装饰层中的图案能够填补目标光伏组件的间隙及边缘,这使得光伏组件背板具有较好的美观性。
