一种太阳能电池背板及其制备方法

Solar cell back plate and preparation method thereof

Abstract

本发明涉及太阳能光伏电池技术领域,尤其是涉及一种太阳能电池背板及其制备方法。为了解决现有太阳能电池背板生产成本较高,生产工艺复杂的缺陷。本发明提供一种太阳能电池背板及其制备方法。本发明提供的太阳能电池背板的结构依次包括耐候层、结构增强层和阻隔层,只有三层结构,但是耐候性和阻隔性较好,生产成本较低,不含氟元素,不会造成环境污染。本发明提供的太阳能电池背板的制备方法,包括三层共挤出和双向拉伸工艺,该方法生产工艺简单,易于实现。
The invention relates to the technical field of solar photovoltaic cells, in particular to a solar cell back plate and a preparation method thereof. In order to overcome the defects of higher production cost and complicated production process of the existing solar cell back plate, the invention provides the solar cell back plate and the preparation method thereof. The solar cell back plate provided by the invention structurally and sequentially comprises a weather resistance layer, a structure reinforcing layer and a blocking layer, only the three-layer structure is adopted, but the weather resistance and the blocking performance are better, the production cost is lower, the fluorine element is not contained, and the environment pollution cannot be caused. The preparation method of the solar cell back plate provided by the invention comprises three-layer coextrusion and two-way stretch process, the production process of the method is simple, and the implementation is easy.
