Flexible battery: Flexible thin-film solar cells are distinguished from conventional solar cells. Conventional solar cells are generally structured with EVA material and solar cells between two layers of glass. Such components are heavier and require brackets during installation and are not easy to move.
Flexible thin-film solar cells do not need to use glass back sheets and cover plates, solar panel and are 80% lighter than double-glazed solar cell components. Flexible cells using pvc back sheets and ETFE thin-film cover sheets can even be bent arbitrarily for easy carrying. There is no need for special brackets during installation, solar panel and it can be easily installed on the roof and used on the top of a tent. The disadvantage is that the photoelectric conversion efficiency is lower than that of conventional crystalline silicon modules.
