Abstract
本实用新型涉及一种低成本、高性能的太阳能复合背板，其特征在于：它从上至下依次包括第一热塑性聚合物层（1）、玻纤布层（2）、第二热塑性聚合物层（3）以及粘结层（4）。本实用新型由于采用两层热塑性聚合物与玻纤布的复合结构，在降低成本的同时，赋予太阳能背板高强度、高耐热性和高绝缘性。为了提高热塑性聚合物与玻纤布的粘结性，玻纤布预先采用热塑性聚合物浸润，粘结层采用透明或白色EVA或PE，在提升与上层粘结性的同时，白色EVA的存在能够提高光线反射率，增强组件的光电转化效率。因此该太阳能复合背板具有机械强度高、耐候性好、层与层之间粘结性较佳、低成本等优点。
The utility model relates to a low-cost, high-performance solar composite backboard, which is characterized in that it comprises a first thermoplastic polymer layer (1), a glass fiber cloth layer (2), a second thermoplastic polymer layer (1) from top to bottom Material layer (3) and adhesive layer (4). Because the utility model adopts a composite structure of two layers of thermoplastic polymer and glass fiber cloth, it endows the solar backboard with high strength, high heat resistance and high insulation while reducing the cost. In order to improve the adhesion between thermoplastic polymer and glass fiber cloth, the glass fiber cloth is infiltrated with thermoplastic polymer in advance, and the adhesive layer is made of transparent or white EVA or PE. While improving the adhesion with the upper layer, the existence of white EVA can Improve the light reflectivity and enhance the photoelectric conversion efficiency of the module. Therefore, the solar composite back sheet has the advantages of high mechanical strength, good weather resistance, good adhesion between layers, and low cost.
