Problems solved by technology

However, after a period of use outdoors, the backsheet of solar modules will gradually age and crack, such as yellowing, pinholes, pulverization, micro-cracking, and cracking, which cannot meet the safety requirements of the module during operation; at the same time , during the transportation and installation of solar modules, some of the backplanes of the modules will be damaged and scratched, which will also lead to safety and functional failures during the operation of the modules
[0003] At present, no suitable repair method has been found for the damaged parts of the solar backplane. Only the damaged components can be replaced completely. This method can only replace a small number of components. If a large number of components are replaced, the cost will be extremely high, and it is difficult to recycle old components. , It is also easy to cause environmental pollution; in view of this background, it is of great significance to develop a repair tape that can be applied on-site, environmentally friendly, free of waste, and low in cost, so that damaged components can operate normally within the warranty period
