Flexible thin film solar cells are distinguished from conventional solar cells:
Conventional solar cells are generally composed of two layers of glass with EVA material and cells in the middle. Such components are heavy, and require brackets during installation, which is not easy to move.
Flexible thin-film solar cells do not need glass backsheets and cover sheets, and are 80% lighter than double-glazed solar cell modules. Flexible cells with pvc backsheets and ETFE film cover sheets can even be bent arbitrarily, making them easy to carry. It can be applied to solar backpacks, solar convertibles, solar flashlights, solar cars, solar sailboats and even solar planes. It is widely used. The disadvantage is that the photoelectric conversion efficiency is lower than that of conventional crystalline silicon components.
There is also a semi-flexible solar panel, which has a high conversion rate and can only be bent at about 30 degrees. The solar panel of this type of product is relatively mature.
