PERC电池背表面钝化的PC1D仿真分析
|
摘要
采用PC1D软件仿真分析钝化发射极及背接触(passivation emitter and rear contact,PERC)电池;模拟结果表明:降低电池的背表面复合速率有利于增强电池性能、提高电池长波响应。PERC电池由于背表面钝化可采用较低的背场厚度;背钝化层中的表面电荷对高背表面复合速率的电池性能的提升作用显著,但在背表面复合速率较低时影响不大;实测得到PERC电池比常规全铝背接触电池的开路电压和短路电流分别增大1.56%和2.56%。
PC1 D software was used to simulate and analyze passivation emitter and rear contact(PERC)cell.The simulation results show that reducing rear surface recombination velocity is helpful to enhance cell performance and improve the long wave response of the cell.The PERC cell can use thin back-field thickness due to back surface passivation;the surface electric charge in the back passivation layer has a significant effect on improving the performance of the cell with a high back surface recombination rate,but it has little effect when the back surfacere combination rate is low.The measured open circuit voltage and short circuit current of PERC cell are 1.56% and 2.56% higher than those of conventional all aluminum back contact solar cells,respectively.
