Stack welding solar assembly

A stitch welding solar assembly mainly comprises toughened glass, an upper packaging adhesive, a battery assembly, a lower packaging adhesive and a backboard. The battery assembly is formed by connecting a plurality of battery strings in series and in parallel, and each battery string is formed by connecting small battery pieces obtained by dividing battery pieces through a laser scribing method in series in a front-back lap joint mode. The lap welding solar module is scientific in structural design, large in light receiving area of the battery pieces, low in production cost and high in attaching force. 一种叠焊太阳能组件，主要包括钢化玻璃、上封装胶、电池组件、下封装胶和背板；所述电池组件由若干电池串并联而成，所述电池串由电池片通过激光划片手段分割成的小电池片前后相互搭接串联而成；所述相互搭接的小电池片之间设置超薄焊带，本叠焊太阳能组件结构设计科学，电池片受光面积大、生产成本低、贴合力强。
