Description
Technical field
The present invention relates to technical field of solar batteries, and in particular to a kind of side of achievable solar battery edge insulation
Method.
Background technology
With developing rapidly for photovoltaic industry, a kind of active demand technological process in market is simple, electricity conversion is high
Solar cell industry technology of preparing reduces photovoltaic generation cost, photovoltaic generation cost is reached with civil power with valency or is less than
The target of civil power price.In the market, there are two kinds into gate technique in the metal of efficient heterojunction solar battery, one kind is silver
Slurry printing, one kind are metal deposit into grid, are seen in cost, production efficiency and linear shape control aspect, and metal deposit is into grid work
Skill is better than silver paste typography.In metal deposit into grid technique manufacturing process, shared by metal into the formation cost of gate figure
Proportion is at a relatively high.And in cell piece film deposition process, phenomenon of the film around plating is easily produced, this phenomenon causes
P faces, the N faces of cell piece are connected with each other, and have a strong impact on the switching efficiency of cell piece and the reliability of component package.In order to avoid around
Phenomenon is plated, to junction battery piece edge after cell piece edge press box or deposition when many companies apply protective paint, deposition using deposition is preceding
Metal etch is carried out, can so make complex manufacturing technology, virtually increases the cost of manufacture of cell piece, and is easily caused brokenly
Piece, broken angle etc. are bad.
The content of the invention
The defects of with regard to above prior art, it is an object of the invention to provide a kind of achievable solar battery edge insulation
Method, solve the problems, such as to cause film around plating phenomenon because of edge unprotect in solar battery sheet manufacturing process.
In order to solve the above technical problems, the present invention proposes a kind of method of achievable solar battery edge insulation, including
Following steps：Photoresist is sticked simultaneously on cell piece two sides, cell piece is fully wrapped around；By the battery after parcel photoresist
The unnecessary photoresist at piece edge removes；It is two-sided to the cell piece progress after the unnecessary photoresist of removal to expose simultaneously, enter simultaneously
Row development；Metal grid lines are deposited on cell piece after exposure, development.
Preferably, the unnecessary photoresist at the cell piece edge is to cut removal by laser equipment or blade apparatus,
And cell piece edge retains 0.5mm~1mm photoresist.
Preferably, the metal grid lines, which are adopted, is electrochemically deposited.
From the above-mentioned description of this invention, compared to the prior art, the invention has the advantages that：
The present invention retains 0.5mm~1mm photoresist at cell piece edge so that will not during subsequent metal deposition
The metal on cell piece marginal deposit, reach P faces, the effect of N faces insulation, can prevent solar cell in electrochemistry well
It is short-circuit between P, N face caused by metal level on cell piece marginal deposit during deposited metal grid line, so as to improve solar cell
Performance and production efficiency.Can seamless combination in the figure formation process flow and equipment of solar cell metal grid lines, simply
Effectively, the effect of cell piece edge insulation protection is realized, harmful effect will not be produced to cell piece.
Brief description of the drawings
The accompanying drawing for forming the part of the application is used for providing a further understanding of the present invention, schematic reality of the invention
Apply example and its illustrate to be used to explain the present invention, do not form inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is a kind of flow chart of the method for achievable solar battery edge insulation of the present invention.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
A kind of method of achievable solar battery edge insulation as shown in Figure 1, comprises the following steps：
S01, photoresist is sticked simultaneously on cell piece two sides, cell piece is fully wrapped around；
S02, the unnecessary photoresist at the cell piece edge after parcel photoresist is removed；
S03, it is two-sided to the cell piece progress after the unnecessary photoresist of removal to expose simultaneously, while developed, cell piece
Still there is a photoresist protection at edge, photoresist will not therefore process and destroy or come off；
S04, exposing, depositing metal grid lines on the cell piece after development, still there is photoresist protection at cell piece edge,
Cell piece edge will not deposit metal, phenomena such as causing cell piece short circuit.
The unnecessary photoresist at the cell piece edge is to cut removal, and cell piece by laser equipment or blade apparatus
Edge retains 0.5mm~1mm photoresist.
The metal grid lines, which are adopted, to be electrochemically deposited.
The present invention retains 0.5mm~1mm photoresist at cell piece edge so that will not during subsequent metal deposition
The metal on cell piece marginal deposit, reach P faces, the effect of N faces insulation, can prevent solar cell in electrochemistry well
It is short-circuit between P, N face caused by metal level on cell piece marginal deposit during deposited metal grid line, so as to improve solar cell
Performance and production yield.Can seamless combination in the figure formation process flow and equipment of solar cell metal grid lines, simply
Effectively, the effect of cell piece edge insulation protection is realized, harmful effect will not be produced to cell piece.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
For people it should be appreciated that the present invention is not limited to the above embodiments, described in above-described embodiment and specification is to illustrate this hair
Bright principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
It all fall within the protetion scope of the claimed invention with improvement.
