Description
Technical field
The present invention relates to field of photovoltaic technology, more particularly to a kind of manufacture method of photovoltaic module.
Background technology
Photovoltaic cell is a kind of electrification component that electric energy is converted into using solar energy, and environment will not be caused during it dirty
Dye, therefore in the case of energy shortage, photovoltaic cell has been extensively studied and applied.
Common photovoltaic module has crystal silicon component and film assembly, wherein again due to the abundant raw materials of crystal silicon component, system
Make technical maturity, and the photoelectric conversion advantage with efficiency high, thus occupy most of market of photovoltaic module.Due to single
Crystal-silicon battery slice can only provide 0.5V to 0.7V output voltage, therefore, it will usually be serially connected by several photovoltaic cells
And form a photovoltaic cell component, to provide the enough voltage that uses, and use the size of voltage to design, then with photovoltaic module
Size it is closely bound up.Also, in view of small size off-network type (off-grid) photovoltaic module market trend development gradually grow, it is small
Size photovoltaic module has gradually caused the great attention of industry.Different from the full-automatic production process of large scale component, mesh
The flow that preceding existing small size photovoltaic module makes mainly is dependent on manpower operation, including：Cell piece cutting, cell piece list
Weldering, series welding, it is laminated, frames up, pasting the processes such as box, particularly in the processes such as the weldering of leading portion cell piece list, series welding, it is necessary to complete by manpower
Into；Only, human weld not only expends a large amount of human resources, weld job time length, and quality stability is not good enough, causes production capacity slow
It can not improve late.In recent years, dealer carries out weld job using automatic welding board technology newly developed, to solve artificial weldering
The problem of connecing.However, the application of welding board can no doubt improve production capacity and ensure welding quality, but it is constrained to bench structure
Design, it is necessary to after cell piece first to be cut into the shape for meeting welding board, follow-up weld job could be carried out, therefore significantly limit
Its application is made.And because of the cell piece after segmentation, it is necessary to a piece of a piece of welding that continues, therefore output efficiency is too low, and then
Reduce wish of the photovoltaic industry using automation equipment production off-network type component.
It is mainly again customizing products plus small size photovoltaic module, has different size size (to mean different using electricity
Pressure, power, electric current) difference, to meet different consumer demands, and for the less photovoltaic module of required size, its electricity
Pond chip size will certainly be less than the size needed for welding board, not meet welding board, just can not now be further continued for using this weldering
Connect equipment and still need to be changed to human weld's operation.Consequently, it is possible to lessen the use range of welding board, also add simultaneously
Difficulty of the small size photovoltaic module in making.
In view of this, a kind of photovoltaic module technology that can be widely used in manufacturing different voltage requirements is still short of, with simultaneously
Meet that process efficiency lifting in small size off-network type photovoltaic industry, yield improve and reduced the demands such as cost of labor.
The content of the invention
The present invention just provide it is a kind of improve off-network type photovoltaic module production efficiency manufacture method, which solve it is above-mentioned these
