Abstract

Silver-aluminum (AgAl) pastes with various aluminum (Al) contents have been synthesized to enhance physical and electrical characteristics of screen-printed n-type mono-crystalline silicon solar cells (SPNMSCs). The improved series resistance and contact adhesion were demonstrated by a 4 wt% of Al contents doped AgAl front pastes (FPs). The achievement of a conversion efficiency improvement of more than 1.7% absolute from 14.6% to 16.3% in SPNMSCs with a 4 wt% of Al content in AgAl FP was explored. The promoted mechanism could be attributed to suitably front-surface-field formed at p + emitter by circulating track supplied from Al powder softened in AgAl FPs during co-firing.

不同铝含量AgAl前糊料增强n型单晶硅太阳电池的物理和电气特性

为了提高丝网印刷n型单晶硅太阳电池(SPNMSCs)的物理和电学性能，合成了不同铝含量的银铝(AgAl)浆料。通过添加4 wt% Al含量的AgAl前糊剂(FPs)，证明了其串联电阻和接触附着力的改善。当AgAl FP中Al含量为4 wt%时，SPNMSCs的转换效率绝对提高了1.7%以上，从14.6%提高到16.3%。在共烧过程中，由AgAl FPs中软化的Al粉末提供的循环轨道在p +发射极形成了合适的前表面场。
