Embodiment 1

[0019] 100 kg of perfluoroalkyl ethyl acrylate with epoxy groups; 0.02 kg of nano-aluminum powder were stirred and blended evenly at a temperature of 10°C with a stirrer; the above blend was introduced into a screw mixing extruder for Blending and extrusion, the temperature is controlled at 25°C, the extrudate is filtered through a 100-mesh filter, the pressure difference between the metering pump and the metering pump is 1 MPa, metered and extruded, and a cast film with a thickness of 100 UM is cast, 10 degrees air cooling, 3 times the draft A flexible or thin-film solar cell fluorine-modified epoxy resin base film is obtained through processes such as high-rate drafting, pulling, and coiling. The performance of the thin-film solar cell using the thin film is 15.2% higher than that of the unused thin-film solar cell.

Embodiment 2

[0021] 100 kg of perfluoroalkyl ethyl acrylate with epoxy groups containing nano-montmorillonite; 0.05 kg of nano-aluminum powder were stirred and blended evenly at -10°C with a stirrer; the above blend Import the screw mixing extruder for blending and extrusion, the temperature is controlled at 290°C, the extrudate is filtered through a 100-mesh filter, the pressure difference between the metering pump and the metering pump is 1MPa, and the casting film with a thickness of 100 UM is cast, 10 degrees Air cooling, 3-fold stretching ratio drawing, pulling, coiling and other processes to obtain a fluorine-modified epoxy resin base film for flexible or thin-film solar cells. The performance of the thin-film solar cell using the thin film is 3.6% higher than that of the unused thin-film solar cell.

Embodiment 3

[0023] 100 kg of hexafluorobutyl methacrylate epoxy resin containing nano-powder; 0.0001 kg of nano-aluminum powder were stirred and blended evenly at 0°C with a stirrer; the above blend was introduced into a screw mixing extruder for Blending and extrusion, the temperature is controlled at 60°C, the extrudate is filtered through a 100-mesh filter, the pressure difference between the metering pump and the metering pump is 1 MPa, metered and extruded, and a cast film with a thickness of 100 UM is cast, 10 degrees air cooling, 3 times the draft A flexible or thin-film solar cell fluorine-modified epoxy resin base film is obtained through processes such as high-rate drafting, pulling, and coiling. The performance of the thin-film solar cell using the thin film is 8.8% higher than that of the unused thin-film solar cell.

Abstract

The invention relates to a fluorine modified epoxy resin-base film for flexible or thin-film solar cells and a preparation method thereof. The film is prepared from the following components in parts by weight: 100 parts of fluorine modified epoxy resin and 0.0001-0.1 part of nano aluminum powder. The preparation method comprises the following steps: blending and extruding the fluorine modified epoxy resin, nano aluminum powder and the like by a screw blending and extrusion apparatus, filtering, introducing into a running die head, cooling, drawing, coiling and the like to obtain the fluorine modified epoxy resin-base film for solar cells. The product is attached to the photic surface of the thin-film solar cell or used as an upper packaging film of the solar cell to directly enhance the generating efficiency of the flexible or thin-film solar cell.

Description

technical field [0001] The invention relates to a fluorine-modified epoxy resin base film for a flexible or thin-film solar cell and a preparation method thereof. By using the film to encapsulate the light-incident surface of the flexible or thin-film solar cell, the efficiency of the flexible or thin-film solar cell can be directly improved . Background technique [0002] Due to the special properties of fluorine atoms, fluorine-containing polymers form a helical structure in which F atoms surround the C-C main chain on the periphery. The C-F bond is very stable, with a bond energy of 485 kJ / mol. The fluorine atoms are arranged very tightly in the outer layer of the carbon skeleton, which can Form a shielding protection for the main chain and internal molecules. Protect the C-C main chain from being damaged by harsh environmental conditions and maintain a high degree of stability. The molecular side groups or side chains of organic fluoropolymer materials contain fluorine...
