Technical field
The present invention relates to new energy and field of energy-saving technology, more particularly to a kind of gold for intelligent photovoltaic component power supply
Categoryization film.
Background technology
Photovoltaic module is generally (common by cover-plate glass, colloid seal material (common EVA), cell piece, back veneer material
TPE, TPT or glass), frame and connection box set at；" hot spot effect " occurs in order to prevent for photovoltaic module all can be in terminal box
Installation bypass back biased diode, when shadow occlusion occurs for cell piece, the electrical effect of the string cell piece is become from " power supply characteristic "
" resistance characteristic ", at this moment diode start, which is isolated from whole system, plays electic protection work
With if being fitted without the diode, the cell piece meeting fast heating blocked may cause monoblock solar panel irrecoverable
Damage；This protective effect easily makes entire array strings that mismatch occur with other array strings, and reduces the power generation effect of photovoltaic plant
Rate begins to use intelligent photovoltaic component to improve the whole generating efficiency of photovoltaic array；However it is mounted with intelligent wiring box
Intelligent photovoltaic component its terminal box need additional power supply, terminal box power supply mode to have：1. being connect with power grid, the disadvantage is that peace
The inconvenience for filling and using；2. being powered to it using the electric energy that solar cell generates, the disadvantage is that when solar panel is in
When night or rainy days, the problem of electricity shortage of intelligent wiring box can be caused；3. being provided by accumulator, the disadvantage is that electric power storage
The manufacturing cost in pond is big, service life is short, and occupied space is big.
Metallized film is the important materials for manufacturing thin film capacitor, by high purity metal（Such as AL, ZN）In high vacuum shape
It melts, evaporate under state, being deposited on medium basement membrane, the film after medium membrane surface forms one layer of very thin coat of metal is just
It is metallized film, is used widely in thin film capacitor field, but because thin film capacitor uses winding method and multiple tracks
Processing technology determines that its capacity is generally little, usually in microfarad（µF）The order of magnitude can only be used when " capacitor ", if metal
Change film size is sufficiently large, and the condenser capacity constituted can be made big, and capacity is up to farad（F）The order of magnitude, this
When capacitor can be used when " accumulator ", and its manufacturing cost is low, service life is long；If by the sufficiently large metallization of area
The plate condenser that film is constituted, is handled, not only very little is elastic again to volume using overlapped way；It is assembled into light again
It lies prostrate in component, photovoltaic module volume there is not significant change.
Invention content
It is insufficient existing for the additional power supply of intelligent photovoltaic component its terminal box needs the purpose of the present invention is being directed to, one kind is provided
It can be used when " accumulator " using the capacitor of its formation for the metallized film of intelligent photovoltaic component power supply, for intelligence
Photovoltaic module its terminal box power supply, then no longer need that accumulator is connect or be used alone with power grid, realize intelligent photovoltaic component
Transportable property, and its manufacturing cost is low, service life is long.
Technical solution
To achieve the above object, present invention employs following technical schemes：A kind of metallization for intelligent photovoltaic component power supply
Film, including basement membrane, first coat of metal for being vaporized on basement membrane film web two sides, second coat of metal；The basement membrane constitutes capacitance
Device organic media, first coat of metal, second coat of metal constitute capacitor power-on and power-off pole plate.
Further, the basement membrane web widths are 500~920mm, can be matched with photovoltaic module width.
Further, the basement membrane is polyester film or polypropylene film.
Further, first coat of metal, second coat of metal are metal Al coating, and metal Al coating is relative to height
Molecular material basement membrane has preferable adhesion property.
Preferably, the basement membrane thickness is 2.5~3.5 μm, and basement membrane thickness is thinner, and the condenser capacity of homalographic is bigger.
Preferably, first coat of metal, the second metal layer thickness are 0.15~0.25 μm, are reduced when conducive to stacking
Thickness value.
Compared with the prior art, the present invention has the following advantages.
1. working as metallized film along longitudinal direction（Length direction）Its area of folding multilayer is just sufficiently large, the capacitor constituted
Capacity is up to farad（F）The order of magnitude, at this time capacitor have enough energy storage effects, can when " accumulator " use, utilize this electricity
Container is powered to its terminal box of intelligent photovoltaic component, it is no longer necessary to which storage battery power supply is used alone in power grid, realizes intelligent light
The transportable property of component is lied prostrate, and its manufacturing cost is low, service life is long.
2. avoiding when the electric energy generated using solar cell powers on it was influenced by night or rainy days, lead to intelligence
The problem of terminal box electricity shortage.
