Description
Technical field
The utility model relates to solar components technical field more particularly to a kind of generating electricity on two sides list glass photovoltaic module knots
Structure.
Background technique
Solar battery is as green energy resource, because luminous energy can be converted directly into electric energy, and increasingly by people's
Concern.Photovoltaic module is with outer enclosure and internal connection, and the minimum that direct current electricity output can be provided separately is indivisible too
Positive energy battery combination device.Conventional list glass component notacoria major part is white composite film material, and in it is multiple come the all-transparent developed
Membrane material is closed to be also applied in single glass component of generating electricity on two sides.
Its back side of its structure of the photovoltaic module of the prior art is as shown in Figure 3, Figure 4, and photovoltaic module structure 100 includes: routine
White notacoria, frame, terminal box.Because the photovoltaic module structure 100 use conventional white notacoria, the back side can not light transmission so that should
Construction package does not have back side power generation performance.Photovoltaic module structure 200 includes: convention transparent notacoria, frame, terminal box.Because being somebody's turn to do
Photovoltaic module structure 200 uses convention transparent notacoria, and wide part of the front illuminated in cell piece gap penetrates transparent notacoria,
So that the light of this part substantially without absorbing again, causes component light leakage to lose.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of generating electricity on two sides list glass photovoltaic module structure, solve transparent
The gap leakage problem of notacoria list glass component, while solving the problems, such as white notacoria list glass module backside without power generation performance.
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: generating electricity on two sides list glass photovoltaic
Modular construction, including preceding glass sheet, cell piece, EVA, white grid notacoria, frame, terminal box, the welding of battery film are formed
Whole cascaded structure is arranged in frame, before the concatenated cell piece of entirety is laid on glass sheet, the preceding glass sheet and
Bedding has one layer of EVA, one layer of EVA of cell piece back side bedding between cell piece, and the white grid notacoria is laid on battery
Cell piece gap, transparent region and each cell piece phase is completely covered in the white net region of on piece, the white grid notacoria
It is corresponding.
Further, the white net region of the white grid notacoria is the high anti-coating of white, and white net region is logical
It crosses printing and is coated in the transparent side composite membrane notacoria EVA, the white net region is coated in transparent composite membrane notacoria by printing
The side EVA, and other regions reservation transparent characteristic without any processing other than white net region.
Further, the grid lines printing width of the white net region is 3mm~20mm.
By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent
Point:
The utility model replaces conventional white notacoria and convention transparent notacoria using white grid notacoria, positive in component,
Light from front illuminated in the spacing gap of component cell piece when because cell gap by notacoria white grid part block,
Before this portions of light is reflected back after glass sheet, because of the patterned structure of preceding glass sheet, so that a part of light is reflected back battery table again
Face increases the absorptivity of light.And the incident light from the back side, the transparent region of notacoria can be penetrated, is inhaled by the back side of double-side cell
It receives, thus the advantages of improving component power, being compatible with prior art list glass component notacoria, while having and reducing pack clearance light leakage
Lose and have the function of back side power generation.
