摘　　要：产业化的薄膜硅太阳电池组件采用激光划刻技术实现子电池的串联集成。基于单个PN结的二级管模型,建立薄膜硅太阳能组件的等效电路模型。薄膜硅太阳能组件的前后电极电阻、激光划刻子电池有效发电宽度、激光划刻死区宽度、激光划刻后Shunt效应等因素会对电池性能产生影响。在实验室小面积薄膜硅太阳能电学参数基础上,对薄膜硅太阳能组件效率进行优化,通过薄膜硅太阳能组件转换效率和子电池激光划刻宽度的关联性量化,确定适宜的激光划刻子电池宽度。Laser scribing process is used to form individual cell series-connection monolithic structure during mass production of thin film silicon solar module.This study is to build thin film silicon solar module equivalent electrical circuit model based on PN junction diode model.The performance of the cell is effected by thin film silicon solar module series resistance of the top and the bottom contact,the monolithic active area,dead area and shunt effect.According to laboratory small test cell electrical parameter,we optimize efficiency of large scale thin film silicon solar module.The influence of individual cell width on the module performance was revealed and demonstrated,and find the optimal individual cell width which gives the highest module efficiency.
