太阳能组件背板需具有可靠的绝缘性和阻水性，以保证组件的正常运行。目前，组件破损主要有两种，一种是组件在运输及安装过程中，部分组件背板会被破损划伤，导致组件运行时的安全性失效和功能失效；另一种是组件在户外使用一段时间后，背板会出现逐步老化开裂现象，达不到组件运行时的安规性要求。The solar module backplane needs to have reliable insulation and water resistance to ensure the normal operation of the components. At present, there are two main types of component damage. One is that during the transportation and installation process, some of the component backplanes will be damaged and scratched, resulting in the failure of the components during operation and functional failure. The other is that the components are used outdoors. After a period of time, the backboard will gradually aging and cracking, and the safety requirements of the components will not be met.
针对破损的背板只能进行组件的更换，若大批量更换则成本极高，旧组件回收难还造成环境污染大。鉴于此背景，开发出一种修补胶带可在现场施工、环保无废弃物、成本低廉，使破损的组件在质保期内能正常运转，具有深远意义。Only the components can be replaced for the damaged back plate. If the mass is replaced, the cost is extremely high, and the recovery of the old components is difficult to cause environmental pollution. In view of this background, the development of a repair tape can be carried out on site, environmentally friendly, waste-free, and low-cost, so that damaged components can operate normally during the warranty period, which has far-reaching significance.
