| 摘 要： | 对不同氧含量的太阳电池用多晶硅片进行了磷扩散吸杂,铝吸杂及磷铝联合吸杂的研究,用准稳态光电导衰减法 (QSSPCD) 和太阳电池效率测试系统测试了吸杂前后多晶硅片的少子寿命和Ⅰ-Ⅴ曲线.发现3种吸杂方式对于多晶硅片的少子寿命和电池效率都有提高,而磷铝联合吸杂的效果最佳;实验发现[Oi]＜10ppma的低氧样品有利于促进吸杂.

| Abstract: | It is described that a series research of heavy phosphorous diffusion gettering, aluminum and combination of aluminum and phosphorous gettering (evaporation of aluminum on the back of the wafers) are used to fabricate multicrystalline silicon solar cells with different impurity concentration of interstitial oxygen. It is found that the minority carrier lifetime of the multicrystalline silicon wafers is improved greatly after getterring (by QSSPCD). The phosphorous/ aluminum co-gettering is found to be the m... |
