Problems solved by technology

[0005] However, the above-mentioned patent scheme has the following two problems: 1. EVA, as the base material of the encapsulation material, has poor UV and damp heat aging resistance, and long-term exposure to ultraviolet rays and water vapor will easily lead to degradation and yellowing. decline
2. Since the spectrum conversion material is an inorganic substance doped with rare earth, it is mixed unevenly with organic matter, and the particles of the spectrum conversion material are bonded, resulting in a decrease in the light transmittance of the packaging film and unstable performance

Description

technical field [0001] The invention belongs to the field of solar cell encapsulation adhesive film and its preparation, in particular to a POE spectrum conversion solar cell encapsulation adhesive film and a preparation method thereof. Background technique [0002] The spectral composition of sunlight covers the wavelength band from ultraviolet to far infrared. As the wavelength increases, the energy of sunlight photons decreases. When sunlight irradiates solar cell semiconductors, part of the energy of ultraviolet light is used to excite and generate hole-electron pairs, and the rest of the energy is lost in the form of lattice heat; far-infrared light cannot be excited to generate hole-electron pairs because of its low energy, and its energy cannot be absorbed Solar cells are utilized and lost. Spectral conversion materials are a class of materials that absorb light of specific wavelengths and emit light of other specific wavelengths. Applying spectral conversion materi...
