| 摘 要： | 研究了不同的晶体硅表面钝化方法,测试分析了硅片的少数载流子寿命以及对晶体硅/非晶硅异质结(HIT)太阳电池性能的影响。发现适当时间的HF溶液处理、氢等离子体处理和表面覆盖约3nm的本征非晶硅层能有效提高硅片的少子寿命,从而提高HIT太阳电池的开路电压。对电池制备工艺综合优化后,得到了基于n型晶体硅的光电转换效率为16.75%(Voc=0.596V,Jsc=41.605mA/cm2,FF=0.676,AM1.5,25℃)的HIT太阳电池。 |

| Abstract: | The surface passivation of silicon substrate has been studied,and the minority carrier lifetime of silicon substrate wafer along with its influence on the crystalline silicon / amorphous silicon heterojunction(HIT) solar cell has been tested and analyzed.It is found that appropriate HF solution treatment,H-plasma treatment,as well as inserting approximately 3nm intrinsic amorphous silicon layer can significantly improve the minority carrier lifetime of silicon substrate,which can improve the open circuit voltage of HIT solar cell sequentially.By comprehensively optimizing the process of HIT solar cell,the conversion efficiency of 16.75%(Voc=596mV,Jsc=41.605mA/cm2,FF=0.676,AM1.5,25℃) on n-type silicon substrate is obtained. |
| Keywords: | crystalline silicon/amorphous silicon heterojunction(HIT) solar cell surface passivation minority carrier lifetime |
