silicon wafer
Solar cell production process
Silicon Chip Selecting
Inspection by the naked eye and scratch.
Texturing
We carry out an anti reflection film so that it does not reflect the incident light on the surface of the cell that absorbs light efficiently. In order to increase the surface area of the cell, and increase the photoelectric conversion efficiency of the cell.
Diffusion
With a silicon wafer phosphorus by diffusion, by creating a N layer will form the photoelectric conversion of the underlying structure of PN junction.
Etching
After spreading, a short circuit ring is formed around the silicon wafer.
PECVD
In order to reduce the reflection on the surface of the main solar cells to form a film.
Screen Printing
The electrode pattern is printed on the backside of the silicon substrate by a screen printing method.
Flash Test
Automatically select output from each unit.
Solar PV module production process
Laying-Out
执行太阳能电池上的白片回火玻璃的顶部彼此,EVA片,然后在后座的顺序叠加的串并联连接,进入层叠处理。
Laminating
在用于加热的装置层压设备而抽空设备内部,EVA薄片是粘在玻璃,通过加热,熔化熔融太阳能电池,并且将被整合。
Post lamination appearance check
发现在目视检查有缺陷的,拒绝将以免分配给下一个步骤。
Frame Assembly
使用内部铝框
Visual Inspection
小心和一个模块检查之一。
Flash Test
输出测试,有一定的标准的光强度,并且模块的在原始温度的测试。
EL Test
你可以看到,不能用肉眼主要标识的损坏。
End Product Inspection
最后目测,输出测试,只有通过EL检验和耐压测试模块将被运。
Packaging
为了成品模块没有在运输中损坏,包装统一包装标准之前,收拾完模块将在不久集装箱航运。
