Description
技术领域technical field
本实用新型涉及一种耐变形柔性光伏组件。The utility model relates to a deformation-resistant flexible photovoltaic module.
背景技术Background technique
目前便携式的光伏组件还是以晶体硅组件为主，由于晶体硅电池片的特性，决定了晶体硅组件绝不能有较大的形变，否则会导致电池片碎裂，从而组件失效；因此所有的晶体硅组件都有一个刚性的衬底材料，可以在表面，如玻璃，也可以在背面，如不锈钢或玻璃钢。这种材料都是大密度材料，这就造成现有组件的重量都相对较重，(玻璃的重量大致占组件总重量的70％左右)。组件重量较大导致在很多场合(比如轻型屋顶)不能安装使用，极大地限制了光伏产品的应用范围。而可移动便携式组件其设计理念就是为了方便携带的，所以为了减轻重量，只能将组件面积尽量减小，这样的后果是组件的功率就大幅度下将了，可以说晶体硅组件的重量和功率已经成为制约光伏组件向便携式光伏产品发展的最重要的因素。At present, portable photovoltaic modules are mainly crystalline silicon components. Due to the characteristics of crystalline silicon cells, crystalline silicon components must not have a large deformation, otherwise the cells will be broken and the components will fail. Therefore, all crystal Silicon components have a rigid substrate material, either on the surface, such as glass, or on the back, such as stainless steel or FRP. These materials are high-density materials, which cause the weight of existing components to be relatively heavy (the weight of glass accounts for about 70% of the total weight of the components). The heavy weight of the components makes it impossible to install and use in many occasions (such as light roofs), which greatly limits the application range of photovoltaic products. The design concept of the portable portable module is for the convenience of carrying, so in order to reduce the weight, the module area can only be reduced as much as possible. The consequence of this is that the power of the module will be greatly reduced. It can be said that the weight of the crystalline silicon module and Power has become the most important factor restricting the development of photovoltaic modules to portable photovoltaic products.
