摘要:
以3种含硼化合物作为添加剂,对背钝化(PERC)太阳能电池铝浆进行了系统地性能研究。其中,Na2B4O7·10H2O的添加质量分数为1.0%时,填充因子最大可达到78.5%,太阳能电池光电转换效率可达到20.2%。通过SEM和EDS对PERC电池片的横截面进行微观形貌表征和元素分析,发现硼添加剂对于PERC电池的局部背表面层(LBSF)的厚度产生一定的影响,从而会进一步影响背钝化太阳能电池的电性能; 另外,EDS结果表明靠近LBSF层及界面铝浆中的硅含量都有增加。因此可以推断,局部背表面层厚度的增加与硼添加剂可以增加铝硅在烧结时的互扩散有关。
Abstract:
Three different boron compounds were used and systematically studied as aluminum paste additives for passivated emitter rear contact(PERC)solar cells. The fill factor(FF)can increase to 78.5% and the photo-electric conversion of the PERC solar cells can reach an appreciable value of 20.2%, when 1.0% of Na2B4O7·10H2O boron additive is added into aluminum paste. The microstructures and elemental analysis of the cross-section of the PERC solar cell were carried out by SEM and EDS. The SEM results show that the boron additive can increase the inter-diffusion between aluminum and silicon atoms during sintering, and meanwhile the the thickness of local back surface field(LBSF)layer can also be controlled, which will affect the electrical properties of the solar cells. In addition, the EDS results indicate that the increased thickness of LBSF layer is related to the increased inter-diffusion. And according to analysis of above results, the possible mechanism of boron-based additives in PERC solar cells was also explored.
