Abstract: A fabrication method prepares a photovoltaic module integrated with a vehicle body. A mold includes an upper mold and a lower mold, the upper surface of the upper mold is a first forming surface, and the lower surface of the lower mold is a second forming surface; then, the two pieces are formed into a first thermoplastic material and a second thermoplastic material of a vehicle body element; the first thermoplastic material and the second thermoplastic material are moved to be between the upper mold and the lower mold; the first thermoplastic material and the second thermoplastic material are made to attach to the second forming surface and the first forming surface, respectively; the upper mold and the lower mold are driven to close, and a photovoltaic module is packaged into the first thermoplastic material and the second thermoplastic material and a finished product is obtained after cooling and shaping.
