中文摘要 |
本研究將利用水溶液沉積法將氧化鋅奈米針成長於氧化鋅結核層,並使用不同的結核層參數生長不同方向性之奈米針。藉由氮氣的低溫回火提高氧化鋅奈米結構的紫外光激發並改善結晶構造,減少缺陷。氧化鋅奈米針可利用其粗化表面和光學影響的特性,在應用上可當作抗反射層。本實驗中將利用氧化鋅奈米針應用於單晶矽太陽能電池上,利用氧化鋅奈米針當抗反射層以增加光穿透率,提升太陽能電池之效率。 |
Abstract |
In this study, we prepare the zinc oxide nanotip with aqueous solution deposited on ZnO nucleation layer. The directions of nanotip are formed with different ZnO nucleation layer time. The thermal annealing with N2 ambiance at 300 ℃ for 1 hr increase the UV emission and decrease the defects. We use ZnO nanotip as an anti-reflection layer because of surface roughness and optical interference. ZnO nanotip with rough surface decreases reflection and enhance the transmission, so we use ZnO nanotip as an anti-reflection layer, after growin ZnO nanotip on solar cell the efficiency of solar cell was enhancement. |
