Background technology
Generating electricity on two sides photovoltaic module:Generating electricity on two sides cell piece can be turned luminous energy by the connected mode of serial or parallel connection
The device of electric energy is turned to, is typically packaged by positive back side safety glass by transparent enclosure glued membrane.
Mainly based on crystal silicon component, main flow component is one side electrification component, passes through EVA, backboard, side in photovoltaic module market
Frame is packaged, and in the market gradually rises solar double-glass assemblies recently, and solar double-glass assemblies are divided into one side generating solar double-glass assemblies, and (such as p-type is more
Brilliant, p-type mono-crystal component) and generating electricity on two sides solar double-glass assemblies (N-type mono-crystal component), and there is generating electricity on two sides component the positive back side can send out
The function of electricity, is mainly mapped to module backside, so as to improve the generated energy effect of photovoltaic module, no by the illumination of ground return
Same reflecting background lifting photovoltaic module generating gain is different, generally 10%-30%.The positive back side of generating electricity on two sides component passes through saturating
Gelatin film is packaged, and can so cause the light of front illuminated to pass through photovoltaic module by non-battery position, the light of this part is not
It can be utilized;On the other hand, welding blocks battery plate illumination, causes the waste of illumination resource, therefore generating electricity on two sides light
The more conventional white backboard photovoltaic component encapsulating loss of front generating encapsulation loss for lying prostrate component is high by about 2% or so.
And the no unified standard of test of generating electricity on two sides component in the market, tested using the front of general components
Power is sold, therefore how to be reduced generating electricity on two sides photovoltaic component encapsulating and lost and ensure the characteristic of generating electricity on two sides have very much must
Will.
