Abstract

本发明公开了一种阳能电池用多晶硅片的编码方法,根据多晶硅片四个边的晶粒数按照顺序进行编排形成编码主体，对编排顺序进行标定作为顺序附加码；对起始边进行标定作为起始附加码；将编码主体、顺序附加码和起始附加码组合形成对多晶硅片进行标记的编码。有益效果：本发明可以对每张硅片进行单独编码，从而方便硅片商以及硅片的下游所有环节准确地追溯到每张硅片的生产厂家以及制造信息，而且该编码信息不会因为周转或加工而丢失。

Description

太阳能电池用多晶硅片的编码方法
技术领域
该发明涉及一种标记多晶硅片的方法，特别涉及一种可以方便追溯多晶硅片信息的太阳能电池用多晶硅片的编码方法，属于太阳能电池技术领域。
背景技术
由多晶硅片制造的太阳电池是最主要的光伏产品，所占市场份额也最大。多晶硅片的制造过程可以简述如下：原料、铸锭、开方、切片、清洗、包装。一般而言，硅片制造商在包装盒上会注明硅片的晶砖、晶锭信息，这些信息在电池片厂商那里，可以方便地追溯片源，控制质量。但是如果电池片制成组件，或者电池片的库存时间变长，或者电池片流转到系统商，再加上许多年的电站运行之后，则很难查到某一硅片的厂商以及制造信息。因此，由硅片而查找到厂商以及生产信息，非常重要。
现有的硅片厂商的编码技术只能将一批硅片的信息得以保留，而不能实现制定、存储和追溯单张硅片的信息。而且，该信息也只能传递到与硅片厂直接联系的电池片厂商，一旦该批硅片进行第二次流转，则硅片的制造信息就会丢失。
发明内容
发明目的：本发明的目的是提供一种太阳能电池用多晶硅片的编码方法，采用该方法可以对每张硅片进行单独编码，从而方便硅片商以及硅片的下游所有环节准确地追溯到每张硅片的生产厂家以及制造信息，而且该编码不会因为周转或生产而丢失。
技术方案：一种阳能电池用多晶硅片的编码方法,根据多晶硅片四个边的晶粒数按照顺序进行编排形成编码主体，对编排顺序进行标定作为顺序附加码；对起始边进行标定作为起始附加码；将编码主体、顺序附加码和起始附加码组合形成对多晶硅片进行标记的编码。每个多晶硅锭厂家每个批次生产的多晶硅片的内部结构是各不相同的，因此通过这个独性可以对多晶硅片进行永久性的标定。
为了进一步对多晶硅片进行区分，所述编码还包括一个长度附加码，所述长度附加码为起始边沿所述顺序方向第二个晶粒沿硅片边缘的晶粒长度。
所述顺序为逆时针的顺序附加码为“A”，所述顺序为顺时针的顺序附加码为“C”；起始边以晶粒数最小的起始附件码为“S”，起始边以晶粒数最大的起始附件码为“B”。
所述编码主体的四个边的晶粒数之间采用“-”相互隔开。
所述编码主体的四个边的晶粒数用三位数表示依次排列。
有益效果：本发明可以对每张硅片进行单独编码，从而方便硅片商以及硅片的下游所有环节准确地追溯到每张硅片的生产厂家以及制造信息，而且该编码信息不会因为周转或加工而丢失。
附图说明
图1为本发明第一实施例的多晶硅片结构示意图；
图2为本发明第二实施例的多晶硅片结构示意图；
图3为本发明第三实施例的多晶硅片结构示意图。
具体实施方式
下面结合附图对本发明作进一步说明。
实施例一
如图所示，采用顺时针顺序、起始边以晶粒数最小的起始，字母与晶粒数之间用“-”隔开，增加晶粒长度附加码，该多晶硅片编码为：CS-6-8-9-7-28。
实施例二
如图所示，采用逆时针顺序、起始边以晶粒数最大的起始，添加字母附加码，字母与晶粒数之间用“*”隔开，该多晶硅片编码为：AB*6*5*4*4。
实施例三
如图所示，采用逆时针顺序、起始边以晶粒数最大的起始，晶粒数统一采用三位数编码，添加字母附加码，该多晶硅片编码为：AB020017016012。
