The invention relates to a solar automobile exterior trimming part structure and a preparation method thereof. The solar automobile exterior trimming part structure comprises a lower-layer adhesive film (2), a solar cell (3), an upper-layer adhesive film (4) and a surface transparent membrane (5) which are sequentially arranged on the outer surface of an automobile exterior trimming plate body (1) from bottom to top. The exterior trimming panel body (1), the lower-layer adhesive film (2), the solar cell (3), the upper-layer adhesive film (4) and the surface transparent membrane (5) are connected through lamination, the thickness of the surface transparent membrane (5) is 0.2-1mm, and the surface transparent membrane (5) and the exterior trimming panel body (1) are made of the same material. Compared with the prior art, damage to the solar cell piece in the using process can be reduced, the efficiency of the solar cell is improved, the using strength and the service life of a vehicle plastic product are met, and the attractiveness of the external shape of the product is kept.
