SOLAR CELL FABRICATION STEPS

Solar Cell Fabrication Steps.

Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.

A photo-voltaic (PV) module is a packaged, new types of solar panels have been occuring, some of the most efficient solar panels are connect assembly of typically 6×10 photo-voltaic solar cells. Photo-voltaic modules constitute the photo-voltaic array of a photo-voltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions (STC), and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few commercially available solar modules that exceed 22% efficiency and reportedly also exceeding 24%. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photo-voltaic system typically includes an array of photo-voltaic modules, an inverter, a battery pack for storage, interconnection wiring, and optionally a solar tracking mechanism.

The most common application of solar panels is solar water heating systems.

 

 There are 12 Steps of Solar Panel Fabrication.

1. 测电池片的功率（把电池片不同的功率分选出来） test cell power 

2. 分选电池片（将电池片按照颜色深浅分类；挑选出来料中的不良电池片） classify the cells with the same color.and pick up the cells with defect .

3. 划片---cut cells

 

    

4.备料。（EVA.TPT）---prepare EVA and TPT

5. 单焊。（对分选好的单片电池片进行焊接，仅焊接电池片正面即蓝色面）----single soldering Ø

6.串焊（将焊好的单片电池片串联焊接起来）---series soldering

7.  叠层---layer up

 第二个图片此处是层叠区，主要看有没有异物。

8.  EL测试。（主要看有没有焊带虚焊及阴影等）----EL TEST

 9.层压（将串焊好的电池片联同封装材料一起层叠起来 ）----lamination

10.    装框。---AL Frame

11.  测试。（成品电性能测试、绝缘耐压测试 ）----test power output

12.  打包。--packing
