Description
Technical field
The utility model belongs to photovoltaic module structure technical field, more particularly to a kind of two-sided lamination of double diode cross version type
Modular construction.
Background technology
Solar cell is a kind of device that luminous energy is converted into direct current using photovoltaic effect.According to photoelectricity
The difference of transition material, solar cell include monocrystalline silicon, polysilicon, amorphous silicon membrane, Cadimium telluride thin film, and copper and indium gallium tin is thin
Film, GaAs, fuel sensitization, perovskite, multiple types such as iii-v multijunction cell.One of the most common is the crystalline silicon sun
Energy battery, including monocrystaline silicon solar cell and polysilicon solar cell.
The technology that stacked wafer moudle is interconnected using special cell piece, optimization battery grid line design and innovation component package skill
Art is designed without main grid by entirety, effectively increases the light-receiving area of component, is utmostly absorbed sunlight and is converted to more
Electric power energy.
The encapsulating structure of single side light is generally used for conventional single side lamination photovoltaic module, photovoltaic module back is using poly-
Object backboard or glass are closed as encapsulating material.Due to being single side light, there is part sunlight to be reflected into light on the ground
When lying prostrate module backside, this part reflected light cannot be utilized to generate electricity, therefore two-sided laminated batteries may be used, and all used in positive and negative
The encapsulation that photovoltaic module is carried out with transparent glass will constitute the solar cell module that can be generated electricity with double-side photic.
However, in general double-side photic photovoltaic module, when one or several single batteries front or the back side by
To when blocking, can also occur as conventional photovoltaic assemblies " hot spot effect ", i.e., these batteries blocked no longer generate electricity, and
It is to be present in photovoltaic module as the resistance of fever, the power output capacity of photovoltaic module is made to subtract greatly.For hot spot effect, often
One or several bypass diodes by being integrated in the terminal box of photovoltaic module by the photovoltaic module of rule on component, PN junction
Structure forms reverse bias parallel-connection structure with solar cell in component, plays the role of by-path turn-on.
Existing single side stacked wafer moudle is most of, and only there are one diodes, have a few components to bridge a remittance by cell backside
It flows item and realizes two diodes.But it for two-sided stacked wafer moudle, is formed naturally since bridging busbar can block back side battery
Hot spot, so only there are one diodes for existing two-sided stacked wafer moudle.In this case, when one or more pieces batteries generation heat in component
When spot, entire photovoltaic module can be short-circuited, and largely effect on the generating efficiency of component.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of two-sided lamination modular construction of double diode cross version type
Problem.
To achieve the above object, the utility model uses following technical scheme：
A kind of two-sided lamination modular construction of double diode cross version type, including positive bus bar, negative bus bar, diode,
Bridge busbar and battery strings；Several string battery strings laid out in parallel, several battery strings are divided into two parts, a portion battery
One end of string is connected by short lead, and is connected to positive bus bar, and the same end of another part battery strings passes through short lead
Connection, and it is connected to negative bus bar；All battery strings of the other end of battery strings are linked together by long conducting wire, and bridging converges
One end of stream item is connect with positive bus bar and negative bus bar respectively, bridging busbar and positive bus bar and negative bus bar
Between be both provided with diode；The other end for bridging busbar connects long conducting wire；Bridging busbar is located at two most intermediate electricity
In gap between the string of pond.
Further, the distance between most intermediate two strings battery strings are more than the distance between other adjacent cell strings.
Further, the original pitch between battery strings is 2.5-3mm, and the distance between most intermediate two strings battery strings are it
Hypotelorism 1-1.5mm between his adjacent cell string and formed.
Further, diode is in parallel with two-sided lamination modular construction.
Compared with prior art, the utility model has following technique effect：
The two-sided lamination modular construction of the utility model, gap of the bridging busbar between battery strings, solves double two
Pole pipe blocks the problem of battery.The version type of double diode greatly reduces the risk of component hot spot, improves assembly reliability；Together
When, the back side is unobstructed so that two-sided high generation efficiency is embodied to the greatest extent；Busbar is positioned among two string batteries
By reflected light so that the sunlight into battery is more, two-sided generating efficiency is improved；Further, bridging welding is placed
Between cell piece rather than the back side, the fragment rate of battery can be reduced, reduce cost.
