Flexible solar thermoelectric device and preparation method thereof

The invention belongs to the field of photo-thermoelectric materials, and particularly relates to a flexible solar thermoelectric device and a preparation method thereof. According to the invention, the radiation refrigeration film prepared by electrostatic spinning is tightly covered on the carbon tube thermoelectric module, so that the flexible solar thermoelectric device is realized. According to the method, the polyvinylidene fluoride-hexafluoropropylene radiation refrigeration film is prepared through electrostatic spinning, the thermoelectric array is prepared through silk-screen printing to construct the flexible solar thermoelectric device, and the method has the advantages of being continuous in preparation process, simple in equipment, rapid, easy to operate, high in cost performance, capable of being produced in a large area, high in yield, short in time consumption, low in energy consumption and suitable for large-scale production. The composite material has the advantages of simple preparation pr
