Description

technical field [0001] The invention relates to a preparation method of a solar cell spectrum conversion encapsulation adhesive film, in particular to a preparation method of a solar cell spectrum conversion polymer film. Background technique [0002] A solar cell is a device that converts light energy into electrical energy, and its main components are tempered glass, packaging film, and solar cells. The spectral composition of sunlight covers the band from ultraviolet to far infrared, and as the wavelength increases, the photon energy of sunlight decreases. When sunlight hits the surface of the solar cell, it is separated into three parts: one part is reflected by the solar cell, one part is absorbed by the solar cell, and the other part directly passes through the solar cell. Due to the nature of the solar cell material, both the high-energy photon part (ultraviolet band) and the low-energy photon part (far-infrared band) of sunlight cannot be absorbed by the solar cell ...
