The invention discloses a light conversion film for a photovoltaic cell, which comprises a film body, an impact-resistant layer, a waterproof layer and a light-transmitting layer. A corrugated layer is arranged on one side of the film body, and the film body is far away from the corrugated layer. One side of the outer wall is provided with an impact-resistant layer, and the center of the impact-resistant layer is provided with polyphenol Yaan, one side of the impact-resistant layer is provided with a waterproof layer, and one side of the waterproof layer is provided with a JS composite waterproof coating, and the side of the JS composite waterproof coating away from the waterproof layer is provided with a polymer cement-based waterproof coating, and the outer wall of the waterproof layer away from the impact-resistant layer is provided with a light-transmitting layer inside the light-transmitting layer One side is provided with polycarbonate, and the side of the polycarbonate away from the light-transmitting layer is provided with polymethyl methacrylate. The invention is equipped with an impact-resistant layer to enhance the impact resistance of the film body to avoid tearing and damage, and by providing a light-transmitting layer, the energy conversion efficiency of the light source of the photovoltaic cell is enhanced to increase practicability.
Description
technical field [0001] The invention relates to the technical field of thin film manufacturing, in particular to a light conversion film for a photovoltaic cell. Background technique [0002] Light energy is the energy form corresponding to photon movement, and the energy released by the light source is converted into electrical energy, and the surface of this kind of solar cell needs a light conversion film to optimize the conversion of the light source and enhance the conversion efficiency and service life of the solar cell. However, there are still many problems or defects in the existing light conversion film for photovoltaic cells: [0003] First, the tear resistance of the traditional light-converting film for solar cells is not high. When the external air volume is too large, it will impact the solar cells and affect the life of the light-converting film; [0004] Second, the traditional light-converting film for solar cells is not waterproof, and rainwater will pene...
