| titleOfInvention | High-performance PVB (polyvinyl butyral) adhesive film for packaging solar cell and preparation method thereof |
| abstract | The invention belongs to the technical field of solar materials. A high-performance PVB adhesive film for packaging a solar cell comprises the following components: PVB resin powder, an organic solvent, a plasticizer, a toughening agent, an organic spectrum conversion material A, an organic spectrum conversion material B, a polar group grafting modifier, a chain silane agent, an antistatic agent, an antioxidant, an ultraviolet light stabilizer and an anti-yellowing agent; the PVB polymerization degree of the PVB resin powder is 900-2500, the acetalization degree is more than 80%, the residual hydroxyl content is less than 20%, and the free acid content is less than 0.05%. The high-performance PVB adhesive film disclosed by the invention has a spectrum conversion function, high light transmittance, good water vapor blocking effect, strong adhesive force, good weather resistance and good stability in a severe environment. The preparation method of the high-performance PVB adhesive film is simple to operate, good in stability and consistency, low in cost and suitable for large-scale production. |
