Description
Technical field
This utility model relates to the photovoltaic tiles of a kind of anti-PID effect.
Background technology
In actual roof electricity generation system, it is in series between tile.When generating tile is in hot and humid ring
In border, the positive and negative lead-out wire of electricity generation system produces high electric potential difference with tile edges, thus forms strong electric field,
Photovoltaic tiles can be made to lose efficacy.General crystal-silicon solar cell is diffusion N-type carrier shape in P-type silicon substrate
Become PN junction.The thickness of P type substrate typically at hundreds of more than μ, majority carrier be " imaginary " out
Hole, and the thickness of N-type launch site only hundreds of nanometers, wherein majority carrier is in esse
Electronics, it is contemplated that the migration that the carrier of inside battery is under electric field action only considers N district.PID is imitated
Should be equivalent to capacity effect, capacitance equation, wherein ξ is the dielectric constant of material between capacitor plate, and S is electricity
The area of container, d is the distance between pole plate, and k is electrostatic force constant.Formula is had to learn: to reduce the face of pole plate
Long-pending S or increase polar plate spacing and can effectively slow down capacity effect from d, and generally conventional crystal silicon cell group
The area of part is fixing, and the recess edge of tile is also fixing, so can only be by reducing tile edges
With the dielectric constant of encapsulating material slows down capacity effect between cell piece.Conventional photovoltaic power generation tile has as follows
Defect:
The electricity generation system of 1, traditional photovoltaic tiles composition there will be PID effect in hot and humid environment, and
Damage the power generation performance of photovoltaic tiles.
2, traditional photovoltaic tiles is heavier, is unfavorable for transport and installs.
The rosette at 3, traditional photovoltaic tiles back side typically uses box-like rosette, and tile entirety is the thickest.
Summary of the invention
For the problems referred to above, the purpose of this utility model is, it is provided that a kind of generating system solving tile composition
PID effect and the photovoltaic tiles of lightweight anti-PID effect present in system.
The technical scheme realizing this utility model purpose is as follows:
The photovoltaic tiles of a kind of anti-PID effect, including transparent front plate, the first EVA adhesive film, crystal silicon cell
Sheet, the second EVA adhesive film, fiber composite and tile substrate,
Described first EVA adhesive film, crystalline silicon battery plate, the second EVA adhesive film, composite bed are in transparent front plate
And it is sequentially overlapped to tile substrate between tile substrate and from transparent front plate,
Described transparent front plate is ETFE transparent front plate, and described fiber composite is FRP composite bed.
Described transparent front plate, the first EVA adhesive film, crystalline silicon battery plate, the second EVA adhesive film, fiber composite
Layer and tile substrate are sequentially overlapped and pass through the encapsulation formation tile of frame.
The outer surface of described tile substrate is provided with bar shaped rosette.
Described crystalline silicon battery plate is 156 single crystal battery sheets, and a photovoltaic tiles has 12 crystalline silicon battery plates
Line up two row tilings to form.
Have employed technique scheme, this utility model stacks order and is followed successively by from top to bottom: before ETFE is transparent
Plate, the first EVA adhesive film, crystalline silicon battery plate, the second EVA adhesive film, FRP composite bed and tile substrate, adopt
It is only the politef ETFE transparent front plate of 1.9 photic zone as generating tile with relative dielectric constant,
So encapsulating material between cell piece and tile recess edge is: ETFE transparent front plate and EVA adhesive film, thus
The problem that can solve photovoltaic tiles electricity generation system PID effect.This utility model has the advantage that
1, PID effect present in the electricity generation system of tile composition can be solved.
2, with safety glass as backboard during FRP composite bed substitutes prior art, power generation tile sheet weight can be made
Alleviate, save transport and the cost installed.
3, on tile substrate, assemble bar shaped rosette, the thickness of photovoltaic tiles can be made to reduce, make tile more
Frivolous.
