低温低压氧化工艺对PERC单晶硅太阳电池性能影响的研究
STUDY ON EFFECT OF LOW TEMPERATURE AND LOW PRESSURE OXIDATION PROCESS ON THE PERFORMANCE OF PERC MONO-Si SOLAR CELLS
摘要
Abstract
In this paper,the PERC mono-Si solar cells using low temperature and low pressure oxidation process are used as the research object,and the silicon dioxide layer prepared at 600~700℃ low temperature and 200 mbar low pressure is used as the passivation layer on the emitter surface of PERC mono-Si solar cells. The performance of this kind of solar cells are tested and compared with that of the PERC mono-Si solar cells without oxidation process. The test results show that the photoelectric conversion efifciency of PERC mono-Si solar cells with low temperature and low pressure oxidation process can be increased by 0.64%and the sheet resistance can be increased by 8.3Ω/□,the minority carrier lifetime can be increased by 59.76μs,and the open-circuit voltage and short-circuit current can be increased by 0.0108 V and 0.13 A,respectively. It can be seen that the low temperature and low pressure oxidation process is an effective way to improve the photoelectric conversion efifciency of PERC mono-Si solar cells. It is expected to improve the reference for the preparation of more efifcient PERC mono-Si solar cells.关键词
