Abstract
The utility model relates to a back board composite film of a solar energy photovoltaic battery assembly, which is formed by compound of the following seven layers of materials: a poly tetra fluoro ethylene (PTFE) rotary cut film (1) with the thickness ranging from 0.028 mm to 0.040 mm, a polyethylene terephthalate (PET) film (2) with the thickness ranging from 0.17 mm to 0.35 mm, a PTFE rotary cut film (3) with the thickness ranging from 0.028 mm to 0.040 mm, a hydrophilic film a, a hydrophilic film b, a hydrophilic film c and a hydrophilic film d. The four hydrophilic films are arranged on the upper surfaces and the lower surfaces of the PTFE rotary cut film (1) and the PTFE rotary cut film (3) respectively. The preparation process comprises the following steps: coating adhesive agent on the upper surface and the lower surface of the PET film, arranging the PET film between the PTFE films and the hydrophilic films, and obtaining the back board composite film after hot-pressing bonding curing. The back board composite film is not formed by imported materials, thereby reducing cost greatly and improving domestication degree. The back board composite film and a solar energy photovoltaic battery adhesive film have excellent adhesive performance.
Description
(1) technical field
The utility model relates to a kind of assembly that is used for solar-energy photo-voltaic cell, is specifically related to a kind of solar photovoltaic battery component rear panel compound film.
(2) background technology
Solar energy is a kind of cleaning, safety and inexhaustible again regenerative resource; needs along with the aggravation and the environmental protection of energy crisis; the development and utilization of solar energy has received increasing concern; in this respect, the conversion of the photovoltaic of solar energy is the fastest research field of development in recent years.
The solar photovoltaic battery component rear panel compound film is the significant components of solar cell, and it is used to protect solar panel and associated components to avoid the influence of outdoor environment.Characteristics such as that the solar photovoltaic battery component rear panel compound film has is ageing-resistant, high-low temperature resistant, anti-solvent corrosion, resistant are hydrophobic can prevent effectively that oxygen, steam, corrosivity gas-liquid and all contaminations from corroding solar cell.
At present, most widely used kind is a TPT type backboard film in China's solar photovoltaic battery component rear panel compound film, it is by up and down two-layer polyvinyl fluoride (PVF) or Kynoar (PVDF) and the compound formation of intermediate layer polyester (PET) trilamellar membrane, important source material polyvinyl fluoride wherein and Kynoar costs an arm and a leg and serious dependence on import, this has seriously restricted China's solar-energy photo-voltaic cell industry development.
(3) utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of cost is cheap relatively, raw material is easy to get and the solar photovoltaic battery component rear panel compound film of excellent combination property.
For achieving the above object, the technical solution adopted in the utility model is: a kind of solar photovoltaic battery component rear panel compound film is composited by seven layer materials:
0.028～0.040mm thick through low-temperature plasma surface-treated polytetrafluoroethylene (PTFE) rotary cut film, respectively (hydrophilic thickness is about 10～200nm), and this hydrophilic membrane grafts on PTFE film surface and contains the polarity hydrophilic radical with a hydrophilic membrane for its upper and lower surface;
0.17 the PETG that～0.35mm is thick (PET) film;
0.028～0.040mm thick through low-temperature plasma surface-treated polytetrafluoroethylene (PTFE) rotary cut film, respectively (hydrophilic thickness is about 10～200nm), and this hydrophilic membrane grafts on PTFE film surface and contains the polarity hydrophilic radical with a hydrophilic membrane for its upper and lower surface.
The utility model solar photovoltaic battery component rear panel compound film, expensive Kynoar and polyvinyl fluoride have been replaced with polytetrafluoroethylene (PTFE) cheap and easy to get, not only significantly reduce cost, and improved the production domesticization degree of solar photovoltaic battery component rear panel compound film.In addition, after the surface treatment of poly tetrafluoroethylene process low-temperature plasma, generated hydrophilic membrane on the film surface, but the viscosity on its surface significantly strengthens, this makes PTFE rete and PET rete that good adhesive property be arranged, also make simultaneously being connected that this rear panel compound film can be more firm, improve the stability of solar-energy photo-voltaic cell integral body with the solar-energy photo-voltaic cell glued membrane.
This rear panel compound film is a raw material with polytetrafluoroethylene (PTFE) and PETG (PET), by precision control, make this rear panel compound film have excellent properties such as the erosion of all contaminations such as ageing-resistant, high-low temperature resistant, anti-solvent corrosion, resistant are hydrophobic, oxytolerant gas, steam, corrosivity gas-liquid, high insulation to the low-temperature plasma surface treatment of PTFE and film combination process.This rear panel compound film has permanently effective protective effect to solar-energy photo-voltaic cell.
