Abstract

The invention discloses solar automobile laminated glass and a preparation method thereof, and belongs to the technical field of laminated automobile glass production. The automobile laminated glass comprises inner piece bent glass, a first film layer, a solar cell, a second film layer and outer piece glass, wherein the film layer and the solar cell are glued together before entering a high-temperature high-pressure environment, and meanwhile, the glue film is not completely solidified, and is melted again after entering the high-temperature high-pressure environment to bond the inner piece glass and the outer piece glass. The preparation process not only ensures that the solar cell is not easy to deviate, but also protects the deformation of the solar cell in the bending process, improves the production yield and improves the appearance of the finished product.
