Abstract

本发明涉及一种晶硅电池片，将晶硅电池片的四周设计成圆角，圆角的半径与晶硅电池的厚度一致。从而减少了晶硅电池的应力集中，增加了晶硅电池的强度和表面积，提高了发电效率。

Description

晶硅电池片
所属技术领域：
本发明涉及一种用于太阳能电池片，特别是涉及一种晶硅电池片的结构。 
背景技术：
1954年贝尔实验室Chapin等人开发出效率为6％的单晶硅太阳能电池到1960年为第一发展阶段，导致效率提升的主要技术是硅材料的制备工艺日趋完善、硅材料的质量不断提高使得电池效率稳步上升，这一期间电池效率在15％。1972年到1985年是第二个发展阶段，背电场电池(BSF)技术、“浅结”结构、绒面技术、密栅金属化是这一阶段的代表技术，电池效率提高到17％，电池成本大幅度下降。1985年后是电池发展的第三阶段，光伏科学家探索了各种各样的电池新技术、金属化材料和结构来改进电池性能提高其光电转换效率：表面与体钝化技术、Al/P吸杂技术、选择性发射区技术、双层减反射膜技术等。许多新结构新技术的电池在此阶段相继出现，如效率达24.4％钝化发射极和背面点接触(PERL)电池。目前相当多的技术、材料和设备正在逐渐突破实验室的限制而应用到产业化生产当中来。目前已经有多家国内外公司对外宣称到2008年年底其大规模产业化生产转换效率单晶将达到18％，多晶将超过17％。 
近年来，电池生产厂家为了降低成本，纷纷减簿晶硅电池的厚度。但是，晶硅电池片为脆性材料，降低厚度后将影响成品率。 
发明内容：
本发明将晶硅电池片的四周设计成圆角，圆角的半径与晶硅电池的厚度一致。从而减少了晶硅电池的应力集中，增加了晶硅电池的强度和表面积，提高了发电效率。 
附图说明：
下面结合附图和实施例对本发明进一步说明。 
附图本发明结构示意图。 
附图中1是晶硅电池过度圆角，2是晶硅电池。 
具体实施方式：
本发明将晶硅电池片(2)的四周设计成圆角(1)，圆角(1)的半径与晶硅电池(2)的厚度一致。从而减少了晶硅电池(2)的应力集中，增加了晶硅电池(2)的强度和表面积，提高了发电效率。 

Claims (2)

1.一种晶硅电池片，其特征在于晶硅电池片的四周设计成圆角。
2.根据权利要求1所述的晶硅电池片，其特征在于圆角的半径与晶硅电池的厚度一致。
