Description

一种基于密集互联技术的光伏电池组件及电池片
技术领域
本发明属于光伏技术领域，具体涉及一种基于密集互联技术的光伏电池组件及电池片。
背景技术
现有常规的太阳能电池组件由多个太阳能电池串组成，每个电池串又由多个电池片通过互联条依次串联而成，一般情况下，所采用的电池片为完整的尺寸为156*156mm规格的电池片。
上述结构形式的电池串的电池片与电池片之间会存在0.5mm～5mm的间距，单位面积内利用率无法最大化，同时连接的互联条相对较厚(厚度一般在0.18～0.27mm)，致使屈服强度也偏大，在实际应用中容易导致电池片隐裂或碎片。
发明内容
为了解决上述问题，本发明提供了一种电池片，避免电池片隐裂或碎片的情况发生。
本发明的技术方案为：一种电池片，包括电池片本体，所述电池片本体包括正面和背面，所述正面的一端设置有正电极，所述背面与正电极相对的一端对称设置有背电极，所述正面还设置有若干个与正电极相垂直的细栅线，所述细栅线之间相互平行布置。
作为优选，所述正电极和/或负电极为镂空或者实心形状，所述正电极和/或负电极由一根电极或者多段电极段组成。
作为优选，所述正电极的宽度为0.5～1.2mm，背电极的宽度为0.6～2mm。
作为优选，所述电池片本体的截面呈矩形形状或者呈带有倒角的矩形形状。
本发明还提供了上述的电池片的制备方法，包括以下步骤：
(1)在整片硅片上画分出多个边框线，使得硅片画分出多个相同规格或相同面积的小电池片区域，其中相邻边框线之间的区域形成切割区域；
(2)在每个小电池片区域上，通过丝网印刷制备得到如权利要求1～4任一所述的电池片结构形状；
(3)采用激光沿着切割区域切割得到如权利要求1～4任一所述的电池片。
作为优选，所述切割区域的宽度为0.2mm～1.2mm。
作为优选，所述硅片的规格为156～180mm。
本发明还提供了一种基于密集互联技术的光伏电池组件，包括多个电池串，所述电池串包括多个串联连接的电池片，所述电池片为上述的电池片，每个电池串中相邻电池片之间的正电极与相邻电池片的背电极重叠且通过导电连接材料导电连通。
本发明通过利用电池片与电池片之间的空白区域，增加单位面积的电池片数量，达到增加输出功率、提高组件转换效率目的。并且通过利用连接电池片与电池片之间正电极和背电极重叠且通过导电连接材料连接导通，改善组件抗隐裂能力，提升组件可靠性。
本发明中导电连接材料有多种，作为优选，所述导电连接材料为柔性树脂材料制成的胶带，所述胶带的宽度为0.5mm～2mm；厚度为0.03～0.1mm。本发明中胶带选用柔性树脂材料制成，其中分布着导电银颗粒、铜颗粒或镍颗粒等等，例如可以选用柔性树脂材料丙烯酸或者环氧体系，在常温下呈带装，在经过热压具有较强粘结力，材料在热压固化后不仅具有柔韧性同时还拥有较低的电阻率特性，在降低组装件隐裂的同时又降低组件的串联电阻。
作为优选，所述导电连接材料为柔性超薄低屈服的焊带，所述焊带的宽度为0.5～2mm，厚度为0.05～0.4mm。本发明中柔性超薄抵屈服的焊带可以为镀锡铜带或者镀银锡铜带等等，材料本身为超薄带装，在加热红外加热或者热风加热后可形成较强粘结力。材料本身后不仅具有柔韧性同时还拥有较低的电阻率特性，在降低组装件隐裂的同时又降低组件的串联电阻。
与现有技术相比，本发明的有益效果体现在：
(1)本发明充分利用了电池片之间的空白区域，增加了单位面积内的可发电的电池片数量，提高组件的功率输出。
(2)采用利用电池片与电池片之间重叠区域的柔性或超薄低屈服材料粘结，改善了组件抗隐裂能力。
(3)根据采用的柔性或超薄低屈服材料粘结材料的低电阻率特性，降低组件的串联电阻。
