摘要

雷射退火和自旋摻雜磷的網印單晶矽太陽能電池的光電特性的影響進行了論證。首先網印單晶矽太陽能電池背面鋁電極會在不同條件下雷射退火。然後討論網印單晶矽太陽能電池射極層上自旋摻雜磷的影響。雷射退火爐的條件，包括雷射功率，頻率，速度，脈衝寬度和形狀​​的圖案。結果表明，利用雷射退火點格局優於掃描線模式的。背面鋁電極雷射退火過程中，網印單晶矽太陽能電池的轉換效率可提高16％至16.6％。為了加強對網印單晶矽太陽能電池射極層上自旋摻雜磷的影響，這項研究討論雷射退火找到最佳的條件。網印單晶矽太陽能電池的轉換效率可從13.7％上升到14.3％。

Effects of laser-firing (LF) and spin-on-dopant phosphorus (SOD-P) on photovoltaic characteristics of screen-printed monocrystalline silicon solar cells(SPMSSCs) were demonstrated in this work. Firstly, the backside Al electrodes of SPMSSCs will be laser-fired under various conditions. Then, the effects of SOD-P on the emitter layer of SPMSSCs were also established. The conditions of LF include the power of laser, the frequency, the speed, the pulse width, and the shape of pattern. The results suggest that the use of the point pattern of laser firing is better than that of the scan line pattern ones. After the LF process on the backside Al electrodes, the conversion efficiency of SPMSSCs can be increased from 16% to 16.6%. To enhance the effects of SOD-P on the emitter layer of
SPMSSCs, this study also discusses the tasks of finding the best condition for laser firing. The conversion efficiency of SPMSSCs can be increased from 13.7% to 14.3%.
