技术领域 technical field
本实用新型涉及将具有光电转换功能的光伏薄膜加工成便于安装的板体的技术领域，尤指一种光伏板，该光伏板为光伏薄膜与光伏薄膜背板的复合板。 The utility model relates to the technical field of processing a photovoltaic thin film with a photoelectric conversion function into a board easy to install, in particular to a photovoltaic board, which is a composite board of a photovoltaic thin film and a photovoltaic thin film backboard.
背景技术 Background technique
随着化石能源的逐步减少和环境保护意识的增强，可再生能源的开发和利用越来越受到青睐。太阳能就是可再生能源的一种。太阳能的一种主要利用方式是通过光伏材料，将太阳的光能转换成电能。光伏材料可以制成薄膜，具有光电转换功能。为了便于安装成大面积的太阳能电站，需要将光伏薄膜制成光伏板。目前的光伏板存在以下不足（指与光伏薄膜复合的光伏薄膜背板）： With the gradual reduction of fossil energy and the enhancement of environmental protection awareness, the development and utilization of renewable energy are becoming more and more popular. Solar energy is one type of renewable energy. One of the main utilization methods of solar energy is to convert the sun's light energy into electrical energy through photovoltaic materials. Photovoltaic materials can be made into thin films, which have the function of photoelectric conversion. In order to facilitate the installation into a large-area solar power station, the photovoltaic film needs to be made into a photovoltaic panel. The current photovoltaic panels have the following deficiencies (referring to photovoltaic thin film backsheets composited with photovoltaic thin films):
其一，电气绝缘性偏低。电气绝缘性低容易造成漏电，影响光伏薄膜的光电转换效果，甚至造成安全隐患。 First, the electrical insulation is low. Low electrical insulation is likely to cause leakage, affect the photoelectric conversion effect of photovoltaic thin films, and even cause safety hazards.
其二，抗形变能力差，尤其是抗冷热变形的能力差。由于光伏板工作在室外的自然环境下，温差变化大，必须具备相当的抗冷热变形的能力，耐热耐寒，尽量减少形变。不然的话，会影响光伏板稳定工作甚至使用寿命。 Second, the ability to resist deformation is poor, especially the ability to resist cold and heat deformation. Since photovoltaic panels work in an outdoor natural environment, the temperature difference changes greatly, so they must have considerable resistance to cold and heat deformation, heat and cold resistance, and minimize deformation. Otherwise, it will affect the stable operation and even the service life of photovoltaic panels.
其三，轻质化不够。一个太阳能电站的光伏板面积很大，必须尽量减轻光伏板的重量，以减轻其支撑架的负荷，减少支撑架投入成本。 Third, the lightweight is not enough. The photovoltaic panels of a solar power station have a large area, and the weight of the photovoltaic panels must be reduced as much as possible to reduce the load on the support frame and reduce the input cost of the support frame.
其四，附着性偏差。附着性影响安装的难以程度和安装的稳定性。附着性好，便于安装，安装稳定性长久。 Fourth, adhesion deviation. Adhesion affects the difficulty of installation and the stability of installation. Good adhesion, easy installation, long-term installation stability.
其五，耐老化抗腐蚀性差。光伏板工作在室外，耐老化抗腐蚀性要强，否则，势必影响光伏板稳定工作甚至使用寿命。 Fifth, the aging resistance and corrosion resistance are poor. Photovoltaic panels work outdoors, and they must be resistant to aging and corrosion. Otherwise, it will inevitably affect the stable operation and even service life of photovoltaic panels.
市场需要一种电气绝缘性好、抗形变能力强、轻质化、附着性优、耐老化抗腐蚀性强的光伏板。 The market needs a photovoltaic panel with good electrical insulation, strong deformation resistance, light weight, excellent adhesion, and strong aging and corrosion resistance.
发明内容 Contents of the invention
