摘要
晶硅太阳电池半片组件是应用激光切割技术将整片电池片切半后封装而成。使用有损激光和无损激光切割电池片,并分析不同激光切割工艺对电池和组件性能的影响。对不同厂家电池片进行不同激光切割后,对电池片进行电性能、切割面外观和机械载荷测试,并对电池片封装后的组件进行电致发光(EL)、功率、机械载荷和湿热老化测试。结果表明无损激光切割在电池电性能、机械载荷、切割面外观和组件老化性能等各方面均优于有损激光切割。随着组件生产使用的电池片越来越薄、尺寸越来越大、间距越来越小,无损激光切割工艺将会成为组件厂商切割电池片的首选工艺。
The half module of crystalline silicon solar cell is encapsulated by half cells which were cut by laser technology.Damage laser and nondestructive laser were used to cut the cells,and the effects of different laser cutting technologies on the performances of the cell and module were analyzed.After the cells from different manufacturers were cut by different lasers,the electrical performance,cutting surface appearance and mechanical load tests of the cells were carried out,and the electroluminescence(EL),power,mechanical load and damp heat aging tests of the module packaged by half cells were carried out.The results show that the nondestructive laser cutting is better than damage laser cutting in aspects of the electrical performance,mechanical load,cutting surface appearance of cells and the aging performance of modules.As the cells used in module production become thinner,larger in size and smaller in space,nondestructive laser cutting technology will become the preferred process for module manufacturers.
