Lose larger.There are two kinds of technologies to reduce cell piece operating current at present.First way is with vertical cell piece main gate line direction
Cell piece is divided into 2 deciles, the operating current of monolithic battery piece is halved, then welds to form interconnection by welding.Second
Mode is that cell piece is divided into some deciles along cell piece main gate line direction, then overlaps to form interconnection by grid line.
Patent [CN106129162A] discloses a kind of solar battery sheet, and it uses new printed pattern, i.e. solar energy
The main gate line of cell piece and the back electrode at its back side are staggered, the position in the same plane of the main gate line and back electrode before substituting
Overlapping design is put, while also discloses such a solar battery sheet composition component, is connected by the way of stacking and welding.It is logical
Cross the mode stacked to be attached, greatly reduce electricity loss, improve the overall generating efficiency of component.
The content of the invention
It is an object of the invention to provide a kind of solar cell module based on quartering section, using new silk-screen printing
Figure, cell piece is divided into four identical regions, each region is a small battery unit, battery unit front main grid line
It is located at the both ends of battery unit respectively with back side main gate line.Compared with patent [CN106129162A], the present invention mainly has as follows
Two aspect advantages：（1）Save the usage amount of battery silver paste and component conducting resinl；（2）Reduce the marking lengths of laser cutting,
Laser cutting efficiency is improved, while also reduces damage of the laser scribe to cell piece.Cell piece is cut according to printed pattern
After cutting, cell piece is divided into four baby battery pieces, then is attached with small pieces cell piece by stack manner, reduces light
Electricity is lost, and improves the generating efficiency of component.
The present invention specifically adopts the following technical scheme that：
A kind of solar battery sheet, it is characterised in that the solar battery sheet center has " ten " word printed patterns, it is described too
Positive energy cell piece is divided into four identical battery blade units, the front of the battery blade unit by " ten " the word printed patterns
Formed by the front main grid line positioned at battery blade unit one end and with the orthogonal some thin grid lines in front of front main grid line；Institute
The back side for stating battery blade unit is made up of the back side main gate line positioned at battery blade unit one end and Al-BSF；The back side main gate line
It is identical with front main grid line length, it is arranged in the both ends of same battery blade unit.
Above-mentioned solar battery sheet presses " ten " word printed patterns quartering and cuts into slices to obtain the solar cell of the present invention
Blade unit.
The present invention also provides a kind of solar cell module, it is characterised in that by some above-mentioned solar cell blade unit phases
Connect and form, adjacent two panels solar cell blade unit, wherein the front main grid line of a piece of solar cell blade unit is led to
Cross the underface that conducting resinl is stacked on the back side main gate line of another solar cell blade unit.
The main gate line at component both ends draws positive and negative electrode and can be used for component interconnection.
The solar battery sheet of the present invention uses new silk-screen printing figure（Center is " ten " font）, cell piece is divided equally
Into four identical regions, in each region, front main grid line and back side main gate line are located at the both ends of baby battery unit respectively.This
Sample, cell piece is cut by " ten " word printed pattern, just obtains four baby battery blade units, every baby battery blade unit just, the back of the body
Respectively there is a main gate line in face.Baby battery blade unit is stacked using conducting resinl and connected, draws positive and negative wiring, you can encapsulation is in groups
Part.
By taking the size of conventional 72 components as an example, the present invention can realize the connection of 75 cell pieces.In identical size feelings
Under condition, component is prepared using the cell piece of same size, in the case of conventional 72 component power outputs are 325 watts, present invention system
Standby component power output can reach 345 watts, reduce photoelectricity loss, and component generating efficiency is greatly improved.With it
He compares the imbrication component of type, and the component that present invention connection is formed can save nearly 30% conducting resinl usage amount, greatly drop
Low cost.
