Description
Technical field
The present invention relates to area of solar cell, particularly relate to a kind of solar module and
Manufacture method.
Background technology
In recent years, due to the problem such as energy shortage and environmental pollution, solar energy become solution these
One of scheme of problem, and developing rapidly along with solaode and semiconductor industry, solar energy
Battery is widely used in every field.Since solaode comes out, how to reduce solar-electricity
The cost in pond and how to improve the conversion efficiency of solaode and be always solar cell working people
The target of member.
Improving the light absorbing ability of solaode is improve conversion efficiency of solar cell important
One of approach, wherein, forms suede structure in solar cell surface, can efficiently reduce too
Sunlight, in the reflection loss of silicon chip surface, is the raising light absorbing energy of solaode in prior art
A kind of important method of power.But, form matte in solar cell surface, need at solar energy
In the manufacture process of cell silicon chip, the method etched by corrosion is completed, and its processing technology is more
Complicated.
And the height of solaode cost depends primarily on for manufacturing silicon chip of solar cell
This height.At present, solaode is typically to be made up of the silicon chip of monoblock, or by multiple whole
The silicon chip of block is in series, and wherein, the area of silicon chip is the biggest, and generating efficiency is the highest.But,
Manufacturing the silicon chip not only complex process that area is bigger, cost is the highest.
Therefore, a kind of processing technology of proposition is needed badly simple, with low cost and can be effectively improved again and turn
Change solar module and the manufacture method thereof of efficiency.
Summary of the invention
It is an object of the invention to provide a kind of solar module and manufacture method thereof, it makes work
Skill is simple, with low cost and can be effectively improved the conversion efficiency of solaode.
According to an aspect of the present invention, it is provided that a kind of solar module, this assembly includes
Packaging body, the first conductive structure, solaode, the second conductive structure and lower package body, its
In: what described upper packaging body was positioned at solaode enters on bright finish, and described solaode has
Front electrode and back electrode, what this front electrode and back electrode laid respectively at solaode enters bright finish and the back of the body
On bright finish, described first conductive structure and the second conductive structure are electrical with described solaode respectively
Connect, it is characterised in that:
Described solaode includes multiple parallel strip solar battery cell, this solar-electricity
The front electrode of pool unit covers the part of described solar battery cell and enters bright finish；
Described first conductive structure includes at least first bus, and described first conductive structure
Front contact electrode with described solar battery cell；
Described second conductive structure includes at least second bus, and described second conductive structure
It is staggered with described first conductive structure；
On the surface of described upper packaging body and/or lower package body, there is light adjustment structure.
Preferably, during described solar battery cell is embedded in described upper packaging body and/or lower package body
Strip groove in.
Another aspect of the present invention, also provides for the manufacture method of a kind of solar module, the method
Including:
A) multiple strip solar battery cell is formed；
B) the plurality of strip solar battery cell is sealed supreme packaging body and lower package body it
Between, it is used for embedding the plurality of strip solar battery cell, in the plurality of strip solar-electricity
The entering between bright finish and upper packaging body and be respectively present between shady face and lower package body of pool unit
The first conductive structure and second for being electrically connected with the plurality of strip solar battery cell are led
Electricity structure；
C) on described, light adjustment structure on the surface of packaging body, is formed.
Compared with prior art, the invention have the advantages that
1) solaode is made up of the solar battery cell of multiple strips, and in prior art
The full wafer silicon chip that usable floor area is bigger forms solaode and compares, and forms described solaode list
Unit, its manufacturing process is simple, and cost is the most relatively low；
2) enter upper packaging body surface on bright finish and form light and adjust being positioned at solar battery cell
Nodule structure, i.e. at upper packaging body surface formation suede structure to reach to fall into light effect, or upper
Packaging body surface forms fresnel lens array to reach the effect of optically focused.Wherein, suede structure can
By again collecting surface emitting light, to reduce the effect of surface reflection loss, the most also may be used
To form sunken light at inside battery, it is reflected by internally reflective and light is trapped in inside solar energy battery, and luxuriant and rich with fragrance alunite
You can converge more sunlight by lens effectively, and two kinds of structures all can improve solar energy significantly
Utilization rate, thus significantly increase the conversion efficiency of battery.Additionally, in upper packaging body surface shape
The technique becoming light adjustment structure is relatively simple, especially forms suede structure on upper packaging body surface
Technique, compared to tradition for solar cell surface forms the technique of suede structure, the simplest
Single, it is also easier to realize.
