Description
Technical field
The present invention relates to photovoltaic solar cell field, more particularly to a kind of anti-PID components and preparation method thereof.
Background technology
In recent years with the continuous consumption of fossil energy and gradually in the gesture of exhaustion, and solar energy can as a kind of green
The renewable sources of energy just gradually come into people’s lives.But the quality problems of home and abroad station occur on a large scale in recent years, many electricity
Station has broken into the quality problem of potential induction attenuation (Potential Induced Degradation, PID) etc., leads to electricity
It stands and is running the decaying for having found that up to 60% for 1 year or so.
PID finger assemblies are for a long time in high voltage operation, and there are leakage currents between cover-plate glass, encapsulating material, frame so that
A large amount of accumulations are on cell piece surface so that the passivation effect on cell piece surface deteriorates, cause fill factor, short circuit current,
Open-circuit voltage reduces, and assembly property is made to be less than design standard.Fearful killer of the PID effects as built photovoltaic power station power generation amount occurs
Basic reason be related with environmental factor and component package material.The formation of PID is easy to occur in a humidity environment, and
Active degree is related to moist degree, while also with assembly surface by electric conductivity, acidity, alkalinity and object with ion
Pollution level is related.
It prevents from present or slows down PID effects to start with from system, component and battery three parts respectively, mainly there are three types of methods
For reducing the sensibility to PID.First, it has already been proven that the encapsulating material for bonding glass and solar cell and backboard
Have on PID and significantly affects, or encapsulating material such as ethane-acetic acid ethyenyl ester (EVA) that resistance low low to the resistance of moisture intrusion
Especially problematic, therefore, PV module manufacturers have tested advanced encapsulating material, as from Dow Chemical
EnlightTM polyolefin, to eliminate PID.However, these materials are often than more there is the competitive materials such as EVA that PID is inclined to apparent
It is more expensive.Second, research has confirmed that the antireflection for being applied to PV batteries itself, passivating coating can have remarkable result, this
It has produced and has been applied using the protectiveness battery that can reduce PID effects including increasing the method design of density and/or thickness sometimes
Layer, the method for such as imporous nitridation silion cell coating, a concurrent problem of silicon nitride modification, which is it, also makes refractive index suboptimum
Change or make technology controlling and process and cost to complicate, increases silicon nitride thickness and increase cost and also reduce overall assembly conversion effect
Rate.Third, research have confirmed that the generation of PID effects is the metal ion precipitation in tempered glass, and conducts and be gathered in battery
Surface is destroyed passivating structure and is formed, therefore can be by being inserted into one layer of colloidal sol between ultrawhite tempered glass and EVA, including gold
Belong to the nanoparticle additives such as SnO of oxide, nitride or carbide2、Al2O3、Si3N4、ZrO2、HfO2And Ce2O3Deng, with
And the carbon nanotube (CNT) of nano-level conducting or at least one of nano silver wire.But this kind of method, nano particle are more difficult
It is even to be scattered in colloidal sol, cause sheet resistance fluctuation larger.In addition, to obtain lower sheet resistance, it is necessary to apply a large amount of nano particle
And nanometer conductive material, this certainly will increase the cost of component, and influence the optical property of component.
Invention content
Technical problem to be solved by the present invention lies in the deficiency for overcoming the above-mentioned prior art, a kind of low cost, no is provided
Influence the anti-PID components and preparation method thereof of transfer efficiency and optical property.

Highest crystalline material, fracture strength (strength degree) are 42N/m2, tensile strength and elasticity modulus be respectively 130Gpa and
1.0TPa, about 100 times of ordinary steel under equal conditions, therefore the application of graphene enhances the rigidity and mechanical load of component
Ability.
Third, graphene and graphene oxide have excellent thermal property, the coefficient of heat conduction be 4.84*103 extremely
Therefore the heat that component generates in the sun is rapidly conducted to glass and aluminium frame, reduces and slow down temperature by 5.3*103W/mK
Influence to assembly property.
4th, graphene ribbon negative electricity, and there is larger specific surface area, either for metal ion or organic matter,
Extremely strong absorption property is all had, therefore, not only the metal ion for causing component PID effects is effectively adsorbed, also
The acetic acid of steam and EVA hydrolysis generations can be absorbed to be made in addition, graphene can carry out Functional Design by doping vario-property
It has more multi-functional.
