Description
Technical field
The present invention relates to area of solar cell, related in particular to a kind of solar cell function EVA glued membrane with light enhancing effect.
Background technology
Existing solar cell EVA glued membrane can not change light wavelength, also hinders the inlet of light, has reduced the opto-electronic conversion effect of solar panel.Existing solar cell EVA glued membrane mainly is sealing, is bonded as the master, does not have other special function.
This solar cell function EVA glued membrane with light enhancing effect of the present invention is to come the modification to former EVA glued membrane through adding one or more compound-materials, can increase optical throughput, increases progressively light wavelength.Make the photoelectric transformation efficiency of solar cell on original basis, improve more than 2% again.
Summary of the invention
The purpose of this invention is to provide a kind of siliceous or titanium-containing compound that in glued membrane, adds, improved optical transmission rate and photoelectric turnover ratio, increased the solar cell function EVA glued membrane of scattering of light and reflecting effect.
In order to solve the problems of the technologies described above, the present invention is able to solve through following technical proposals:
Solar cell function EVA glued membrane comprises the raw material of following weight part:
100 parts of ethylene-vinyl acetate copolymers;
0.1～15 part of linking agent;
0.05～3 part in oxidation inhibitor;
0.01～5 part of photostabilizer;
0.01～1 part of silane coupling agent;
0.1～20 part of titaniferous/silicon-containing compound;
0.1～6 part of glossing agent.
As preferably, described 0 ~ 0.6 part of the tackifier that also comprise.
As preferably, described tackifier are selected γ-An Bingjisanyiyangjiguiwan for use.
As preferably, described linking agent is a peroxidized t-butyl perbenzoate (TBPB), 2,5-dimethyl--2, two (t-butyl peroxy) hexanes, 2 of 5-, 5-dimethyl--2, any in two (t-butyl peroxy) hexanes of 5-.
As preferably, described oxidation inhibitor is tricresyl phosphite (single nonyl benzene and dinonyl benzene mixed ester).
As preferably, described photostabilizer is two (2,2,6,6 tetramethyl-s-4-piperidyl) sebates.
As preferably, described silane coupling agent is selected kh-570CAS or KH-570 for use.The present invention has added silane coupling agent in function EVA glued membrane, can improve matrix material machinery performance, electric property, light transmission, particularly can increase substantially the green property that meets material.
As preferably, described titanium-containing compound be in titanium silicide, titanium sesquioxide, four titan-alkoxides, acyl group titanium and the titanium chelate any.
As preferably, described silicon-containing compound is silicon-dioxide, titanium silicide, triethyl silicane, pure aluminium silicate, silicon single crystal or polysilicon.
Function EVA glued membrane of the present invention is because of having added siliceous or titanium-containing compound.The different compounds crystal has its crystals with different structure; The crystals with different structure can produce different luminous reflectance effects.When scattering of light during at plane of crystal crystals with different corner angle and its faceted pebble can make light produce secondary or multiple reflection and refraction effect, can play:
A: can make light wave produce the repetition scattering, increase the light wave amount.
B: can make a part of invisible light wave change visible light wave scope into.The light quantity of impelling the silicon wafer battery to absorb and changing is more.
As preferably, described glossing agent is selected liquid plastics brightener ZEP-2 or ASK auxiliary agent for use.Added glossing agent in the function EVA glued membrane of the present invention, increased the repeatedly refraction effect of glued membrane light.Because of the EVA resin inner and outside form many naked eyes observed less than micro-air hole and surperficial capillary hole; These minute apertures and capillary hole can cause the low outside formation diffuse-reflectance of product internal optical transmission, and internal optical transmission and the outside reflecting rate that product is improved in surperficial capillary hole filled in the inner micro-air hole of eliminating thereby the effect of adding lustre to can let resin.
Function EVA glued membrane of the present invention is the percent crystallinity that adds the original EVA glued membrane of one or more compound-material modifications.These compound-materials can play the effect that changes and increase to light.These compound-materials are organic materials and inorganic materials.Used organic materials is like organic siliceous compounds and organic titanium compound that contains among the present invention.Like type siloxane, triethyl silicane, four titan-alkoxides, acyl group titanium and titanium chelate etc.
Used inorganic materials is like inorganic silicon-containing compound and inorganic titaniferous Barbiturates compound among the present invention.Silicon-dioxide, pure aluminium silicate, titanium silicide etc.Also can be silicon crystal material and titanium compound crystal: polysilicon, silicon single crystal, titanium sesquioxide etc.
These compounds evenly closely mix with the EVA glued membrane.When light during through these compounds itself do not absorb light source, it can reflect photon, and light is reflected on its surface repeatedly, this has just increased light quantity.These compounds can also involve invisible light to the low light level and have transition function, are transformed into visible light to a part of invisible light source.Bigger increase light quantity, improved silicon chip to the photoelectric efficiency of conversion.
Function EVA glued membrane technology of the present invention and condition are:
Earlier with Injecatable EVA Copolymer EVA, linking agent, oxidation inhibitor, the steady agent of light, tackifier, require to pour into and mix charging basket and under the speed of setting, mix by weight; Mixing time is put into glossing agent successively after 20 minutes; Titanium compound or silicon compounds, coupling agent mixes once more after double-screw extruding pelletizing, and pellet is through film-forming system: curtain coating, cooling, draw, batch etc. obtains the sun power encapsulation with function EVA glued membrane.
The present invention has significant technique effect owing to adopted above technical scheme:
1: change percent crystallinity through adding different organic class or mineral-type materials, increase scattering of light and reflecting effect, improve light conversion efficiency to the EVA glued membrane.
2: change the light wavelength scope through adding titaniferous or silicon-containing compound crystal, reach the increase of light quantity, improve photoelectric transformation efficiency.
