    • Disclosed is a back sheet for a solar cell module for photovoltaic power generation, including a first resin layer attached to EVA under a solar cell, a heat conductive layer formed on the lower surface of the first resin layer, a lower layer formed on the lower surface of the heat conductive layer, and an adhesive layer formed between the first resin layer and the heat conductive layer, wherein the lower layer is a heat conductive coating layer using an inorganic coating or organic-inorganic hybrid coating, or a second resin layer. The back sheet of the invention includes the first resin layer, the adhesive layer, the metallic heat conductive layer, the lower layer and the adhesive layer, thus increasing a withstanding voltage and ensuring an insulation thickness by virtue of the first resin layer, thereby improving insulation performance, wherein the heat conductive coating layer introduced as the lower layer exhibits high heat conductivity, emissivity and reflectivity to obtain high heat dissipation performance, thereby increasing the power generation of the solar cell module, or wherein the second resin layer introduced as the lower layer increases a withstanding voltage and ensures an insulation thickness, thereby enhancing insulation performance and preventing the heat conductive layer from warping due to differences in coefficient of thermal expansion and cooling rate between the adhesive layer and the heat conductive layer, and also wherein the production cost is decreased to thus increase profitability and productivity is raised by 30% or more compared to conventional solar cell modules.
    • 公开了一种用于光伏发电的太阳能电池模块的背板,其包括在太阳能电池下附着于EVA的第一树脂层,形成在第一树脂层的下表面上的导热层,形成在下部的下层 导热层的表面和形成在第一树脂层和导热层之间的粘合层,其中下层是使用无机涂层或有机 - 无机复合涂层或第二树脂层的导热涂层。 本发明的背板包括第一树脂层,粘合剂层,金属导热层,下层和粘合剂层,从而增加耐受电压并且通过第一树脂层确保绝缘厚度,从而改善 绝缘性能,其中作为下层引入的导热涂层表现出高导热性,发射率和反射率,以获得高的散热性能,从而增加太阳能电池组件的发电,或者其中引入的第二树脂层为下层 层增加耐受电压并确保绝缘厚度,从而提高绝缘性能并防止导热层由于粘合剂层和导热层之间的热膨胀系数和冷却速率的差异而翘曲,并且其中生产成本 减少,从而提高盈利能力 与常规太阳能电池模块相比,生产率提高了30%以上。
