Problems solved by technology

At present, EVA is commonly used as the encapsulation material for solar panels, which has the characteristics of high light transmittance, high elasticity, low processing temperature, good melt fluidity and fusion adhesion, etc. EVA itself also has some problems, such as moisture and heat aging resistance The ability and UV aging resistance are poor, and it is easy to degrade and turn yellow, which will greatly reduce the energy conversion efficiency of solar cells

Description

technical field [0001] The invention belongs to the technical field of solar cell materials, and in particular relates to a solar cell light conversion encapsulation adhesive film and a preparation method thereof. Background technique [0002] The shortage of energy has seriously affected people's life and restricted the development of society. Abundant solar energy is an important clean energy, an inexhaustible, inexhaustible, pollution-free, cheap energy that human beings can use freely. After the first oil crisis, countries competed to carry out research on the application of clean and renewable energy such as solar energy, water energy, and wind energy, especially the application of solar energy is the most extensive. [0003] As a kind of green energy, solar energy has no pollution to the environment, and its source is simple, so it can be said that it is inexhaustible within the life span of human beings. Solar energy is not only a one-time energy source, but als...
