摘要
本文对IBC-SHJ电池背面的几何尺寸进行二维仿真和优化,得到缓冲层、发射极和背面场对J-V特性的影响,以及FF因子的变化,结论表明缓冲层获得最佳效率的宽度值为10nm附近,发射极宽度的效率最优值约为3mm。
In this paper,the geometric dimensions of the back of IBC-SHJ battery were simulated and optimized in two dimensions.The influence of buffer layer,emitter and back field on j-v characteristics,as well as the change of FF factor were obtained.The conclusion shows that the width value of buffer layer for optimal efficiency is around 10nm,and the optimal efficiency value of emitter width is about 3mm.
