Description
技术领域
本发明涉及一种太阳能光伏组件焊带。
背景技术
世界能源供应日益短缺，传统能源的大量利用造成自然环境污染和人类生存环境恶化的主要原因之一，寻找新兴能源已成为世界热点问题。在各种新能源中，太阳能光伏发电具有无污染、可持续、总量大、分布广、应用形式多样等优点，受到世界各国的高度重视。光伏发电作为理想的可再生能源发电技术，前几年在国内得到的了迅猛的发展。从我国未来社会经济发展战略路径看，发展太阳能光伏产业是我国保障能源供应、建设低碳社会、推动经济结构调整、培育战略性新兴产业的重要方向。“十二五”期间，我国光伏产业将继续处于快速发展阶段，同时面临着大好机遇和严峻挑战。国内光伏产业在很多方面仍存在较大差距，国际竞争压力不断升级。提升太阳能电池的效率，降低太阳能电池及光伏系统的成本仍将是光伏产业发展的目标。光伏焊带是光伏电池的必须组成部分，光伏焊带又称镀锡铜带或涂锡铜带，分汇流带和互连条，应用于光伏组件电池片的连接，起到收集光伏组件的电流的作用，引出太阳能电池片的正负电极。现在普遍使用的光伏焊带宽1.8mm或1.6mm的比较常见些，但上述传统焊带加工比较单一。
发明内容：
本发明的目的是针对现有光伏焊带存在的问题，提供一种可以降低成本加强发电效率的光伏焊带。
本发明的目的是通过以下技术方案解决的：
本发明提供一种能加强转换效率的太阳能焊带，其特征在于：所述焊带基条为铜带表面压有W型加强筋。
本发明的优点是易加工，加强了焊带的拉伸强度；易焊接，加强了焊带与硅片的吸附力，同时也加强了电子的传送效率，从而提高电池片的发电效率，保证了高效电池的实现。
附图说明
图1、本发明太阳能焊带表面示意图
图2、本发明截面结构示意图
图中：1-焊带，2-W型筋。
具体实施方式
以下结合附图进一步详细说明实施方式
参见附图1：定尺好的铜丝穿过压延机，经压延机压延成型铜带退火，再经W型模具成型所需焊带1，W型筋2的深度决定强度，可根据客户的需求来定(本实施例W型细筋底宽0.02mm，深0.04mm)，由于有多余的焊锡沉在W型细筋内，与硅片焊接后就可加强焊带与硅片的连接强度，增加焊接面积，也就增加了电子的传送效率，从而提高电池片的发电效率，保证了高效电池的实现。
