前表面场结构参数对IBC太阳电池电学性能的影响
Influences of front surface field structural parametrs on IBC solar cells' electrical performance
摘要
Abstract
The influences of front surface field(FSF)'s surface concentration and diffusion depth on N-type interdigita-ted back contact(IBC)mono-crystalline silicon solar cells' electrical properties are studied in detail by using the TCAD semiconductor device simulation software.The effect of improving IBC solar cells' electrical properties by using FSF structures is analyzed and evaluated under different conditions of surface recombination rate,emitter area coverage ratio and substrate resistivity,and the optimal FSF structural parameters are given under different condi-tions.The simulation results show that IBC solar cells' FSF structure improves solar cells' electrical performance. The effect of FSF structure's improving IBC solar cells' electrical properties is different under different surface re-combination rate,emitter area coverage ratio and substrate resistivity.The improvement effect is more significant under higher front surface recombination rate and lower emitter area coverage ratio.Under the lower substrate resis-tivity,the effect of improvement of front surface field structure on the electrical propertie is slightly better than that under higher substrate resistivity.关键词
