Abstract
The utility model relates to a kind of photovoltaic module, especially a kind of MWT hollow out photovoltaic module belongs to MWT solar cell module processing technique field.The structure of the utility model is by the component by surface layer, EVA, cell piece, insulating layer, copper foil, EVA and bottom are laminated, and connection outline border group is integral, the bottom link box, the insulating layer and copper foil are equipped at least one corresponding vacancy of position, constitute hollow out shape.The utility model has the advantages of simple structure, easy to use, the beneficial effect is that: compared with prior art, the light transmittance of MWT hollow out photovoltaic module provided by the utility model is at least up to 10% or more, meets the installation site big to light intensity demand.
Description
Technical field
The utility model relates to a kind of photovoltaic module, especially a kind of MWT hollow out photovoltaic module belongs to MWT solar-electricity
Pond component processing technique field.
Background technique
Conventional MWT photovoltaic module uses transparent back panel or glass, and the light accounting that can penetrate component is still seldom,
Light permeation parts accounting is unable to satisfy the installation site for having demand to light intensity less than 5%, more using being limited.
Utility model content
Purpose of utility model: aiming at the problem that photovoltaic module existing in the prior art is unable to satisfy light intensity, one kind is proposed
MWT hollow out photovoltaic module meets production requirement while improving light transmittance.
The utility model is achieved through the following technical solutions purpose: a kind of MWT hollow out photovoltaic module, the component is by table
Layer, EVA, cell piece, insulating layer, copper foil, EVA and bottom are laminated, and connection outline border group is integral, the bottom link
Box, the insulating layer and copper foil are equipped at least one corresponding vacancy of position, constitute hollow out shape.It can allow more light
Through the installation environment that satisfaction requires light.
With above-mentioned technical proposal correspondingly, the route of the copper foil is connected to around vacancy.Position corresponding to the vacancy
Without cell piece.Increase the transmitance of light.
The surface layer is glass or transparent cephacoria.The bottom is backboard or glass.Conductive tin cream is printed on the copper foil
It is connect with insulating layer.Lead-out wire is fixed on the bottom, the lead-out wire and the binding post of the terminal box are fixed.
The utility model has the advantages of simple structure, easy to use, the beneficial effect is that: compared with prior art, the utility model
The light transmittance of provided MWT hollow out photovoltaic module is at least up to 10% or more, meets the installation site big to light intensity demand.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment insulating layer.
Fig. 2 is the structural schematic diagram of copper foil in Fig. 1.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate.
Embodiment one
The structure of the present embodiment is as shown in Figs. 1-2, and a kind of MWT hollow out photovoltaic module, the component is by surface layer, EVA, battery
Piece, insulating layer, copper foil, EVA and bottom are laminated, and connection outline border group is integral, bottom link box, insulating layer 2 and copper foil 3
It is equipped at least one corresponding vacancy 1 and 1 " of position, constitutes hollow out shape.More light can be allowed to penetrate, met to light
The installation environment that line requires.The route of copper foil is around vacancy connection.Position corresponding to vacancy is without cell piece.Increase light
Transmitance.Surface layer is glass or transparent cephacoria.Bottom is backboard or glass.Conductive tin cream is printed on copper foil to connect with insulating layer.
Lead-out wire is fixed on bottom, lead-out wire and the binding post of the terminal box are fixed.
When production, conductive backings or glass feeding, print conductive tin cream, place insulating layer, placing battery plate, place EVA,
Place glass or transparent cephacoria, lamination, attaching wire box；Conductive backings are 3-tier architecture, and backboard+EVA+ copper foil is multiple by high temperature
It is combined；Copper foil circuit is performed etching with laser, and unwanted part is removed；Insulating layer is punched using laser, more
Remaining part machine is sucked out automatically, and holding position consistency is wanted in insulating layer and the copper foil design of hollowed out area；Lamination；Wiring is installed
Four lead-out wires are first welded when box, then terminal box gluing is fixed on backboard, then lead-out wire is welded on connecing in terminal box
On terminal, last encapsulating solidification, establishment of component is finished.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, without departing from the principle of this utility model, can also make several improvements, these improvement also should be regarded as
The protection scope of the utility model.
