Problems solved by technology
[0003] The flexible photovoltaic module for satellites uses a transparent polyimide film with a thickness of no more than 100 microns as the front film. Problems: (1) Under the attack of atomic oxygen, the peeling force between the component packaging materials decreases, and the packaging materials partially fail, resulting in a decrease in component reliability; (2) Under high-intensity ultraviolet radiation, the transparent PI film (polyamide imide film) appears yellowing, and its light transmission efficiency decreases, resulting in a significant decrease in the power generation of photovoltaic modules

Abstract
The invention relates to the technical field of photovoltaic modules, in particular to a method for manufacturing a front film coating of a flexible solar module for satellites, comprising the steps of: selecting a transparent PI film and processing it; making a coating solution for an anti-atomic oxygen-resistant ultraviolet radiation coating; Oxygen UV-resistant coating solution is plated on the transparent PI film to form a coating, and the production is completed. The beneficial effect: the present invention evaporates a layer of anti-atomic oxygen and UV-resistant coating on the surface of the transparent PI film, not only does not change the transparent PI film itself At the same time, because of the increased coating, the anti-atomic oxygen and ultraviolet radiation resistance of the front membrane of the module are enhanced, so that the on-orbit running time of the flexible photovoltaic module for satellites is significantly increased, and the power generation capacity is not significantly reduced. Adding a coating to a transparent PI film is a mature process, and there are no technical obstacles.
