Description
技术领域 technical field
本发明涉及太阳能光伏发电设备领域，特别是涉及一种耐久性光伏组件。 The invention relates to the field of solar photovoltaic power generation equipment, in particular to a durable photovoltaic module.
背景技术 Background technique
光伏组件（也叫太阳能电池板）是太阳能发电系统中的核心部分，也是太阳能发电系统中最重要的部分，其作用是将太阳能转化为电能，或送往蓄电池中存储起来，或推动负载工作。 Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system.
太阳能光伏组件的结构主要包括上盖板、粘结剂、电池片、背板、边框和接线盒。封装好的光伏组件需要露天放置，使用一段时间后空气中的灰尘颗粒物会吸附在光伏组件的盖板上，形成阻光灰尘覆盖层，从而降低光伏组件的光电转化率，同时大块不透光污染物覆盖还会产生热斑效应，导致光伏组件局域高温直至烧毁报废。由此可见，太阳能光伏组件的自然抗性差，长期暴露在空气中会出现效率衰减、表面堆积成灰后难以清除等问题，因而现有的光伏组件的光电转化效率较低、使用寿命一般不能超过20年。 The structure of a solar photovoltaic module mainly includes a top cover, an adhesive, a cell, a backplane, a frame and a junction box. The packaged photovoltaic modules need to be placed in the open air. After a period of use, the dust particles in the air will be adsorbed on the cover plate of the photovoltaic module, forming a light-blocking dust covering layer, thereby reducing the photoelectric conversion rate of the photovoltaic module, and at the same time, the large pieces are opaque The coverage of pollutants will also produce a hot spot effect, which will lead to local high temperature of photovoltaic modules until they are burned and scrapped. It can be seen that the natural resistance of solar photovoltaic modules is poor, and long-term exposure to the air will cause problems such as attenuation of efficiency, accumulation of ash on the surface, and difficulty in cleaning. Therefore, the photoelectric conversion efficiency of existing photovoltaic modules is low, and the service life generally cannot exceed 20 years.
