Plate, is provided with, in PCB glass-fiber-plate lower surface, the power supply output printed circuit being connected with crystal silicon solar energy battery string both positive and negative polarity, in crystalline substance
Bonding EVA adhesive film and PET film successively above body silicon solar cell string.
The present invention further improvement is that：PCB glass-fiber-plate is the one side PCB glass-fiber-plate that one side is coated with copper film, and it does not plate
The one side of copper film is bonding with crystal silicon solar energy battery string；PET film is frosted PET film；Crystal silicon solar energy battery string passes through double
Face adhesive tape is bonded together with one side PCB glass-fiber-plate；Welding surface above solaode string is bonded with masking tape.
A kind of manufacturing process of solar module, comprises the following steps：
The first step, the one side being coated with copper film in PCB glass-fiber-plate produces power supply output printed circuit, by crystal silicon solar
Battery strings are bonded in the another side of PCB glass-fiber-plate, by power output circuit and the output both positive and negative polarity weldering of crystal silicon solar energy battery string
Connect.
Second step, the one side that PCB glass-fiber-plate is bonded with crystal silicon solar energy battery string is above, in crystal silicon solar electricity
Above the string of pond, sequential layer stacks and puts and bonding EVA adhesive film and PET film successively.
3rd step, the solar module placing is put in firing equipment heating, and its heating-up temperature is 80 DEG C-
140℃.
4th step, after treating that hot-fusible high-molecular glued membrane melts, puts it into and utilizes negative pressure of vacuum heat in negative pressure of vacuum equipment
Overlay conjunction, thus various pieces are bonded together, be manufactured into sun-generated electric power.
Further improvement is that of this method：
In the first step, PCB glass-fiber-plate is coated with the one side PCB glass-fiber-plate of copper film using one side；Crystal silicon solar in the first step
Battery strings do not have the one side of copper plating film to bond together by two-sided tape with one side PCB glass-fiber-plate；Solar-electricity in second step
The welding surface bonding masking tape of pond string top；PET film is frosted PET film.
Have the beneficial effects that using produced by technique scheme：
1st, adopt frosted PET to substitute traditional safety glass, not only reduce the raw material making solar module
Cost, and reduce the weight of battery component；And frosted PET is during normal use, it is not likely to produce pellicle and scratches phenomenon.
2nd, adopt two-sided tape self-contained battery string, the offset phenomena that battery strings produce in lamination process can be prevented, and
Use cost is relatively low, bonding is easy, will not produce the volatilization of harmful substance, pollution-free, environmental protection.
3rd, adopt masking tape to paste welding, improve the sight of assembly, make assembly have more texture.Traditional solar-electricity
Pond assembly, connect battery welding be often human weld, or equipment welding (application class solar module be manual welding
Connect)；During using flatiron, because dynamics is different, it is different, therefore that the scolding tin above welding melts effect to operator
Decorative pattern can be produced above welding, have impact on component facade.The masking tape of different colours can be utilized to change traditional weldering simultaneously
The color (silver color) of band, strengthens aesthetic property.
4th, component thickness can be adjusted, to meet the use of different Application of Solar Energy products.By thick to EVA adhesive film
Degree, the adjustment of number, manufacture out the solar module of different-thickness.
Therefore, this product simple production process, low cost；The sun of different colours, thickness can be produced according to different demands
Can battery component.
