摘要
设计了基于SILVACO-TCAD仿真工具的具有ITO/Si/Al结构太阳电池单元,研究了在此结构中pn结特性对光电流的影响。研究表明,pn结位置越浅,光电流越大;光电流随pn结中杂质浓度增加而先增加后减小,电流极值向短波方向移动。
Solar cells with the structure of ITO/Si/Al were designed based on the simulating tool of SILVACO-TCAD.The relationship between photocurrent and the characteristics of pn junction was investigated.The simulation results show that the lower the depth of pn junction is,the larger the photocurrent is;the photocurrent increases firstly and decreases latterly with the increase of the impurity concentration in pn junction,and the maximum point of photocurrent moves to the direction of short wave.
