在本篇論文中，將聚(3-己烷基噻吩): [6,6]-苯基碳61丁酸甲酯(P3HT:PCBM)有機太陽能元件結合溶液製程的氧化鎳薄膜介面層，增強太陽光電池元件的效率及元件生命。
透過動態光散射儀(DLS)、解析場發射掃瞄式電子顯微鏡(SEM)、原子力顯微鏡(AFM)、高解析X光光電子能譜儀(HRXPS)......等量測設備量測，討論氫氧化鎳顆粒大小、薄膜厚度、表面形態、成分組成、主動層厚度、退火溫度、電極改良是如何影響太陽光電池元件效率，並使用氧化鎳薄膜和PEDOT:PSS為電洞傳輸層的有機太陽能電池效率以及壽命的比較，發現使用氧化鎳薄膜的太陽光電池元件不僅效率表現比較優異，壽命也比PEDOT:PSS的元件還要來的長。
研究發現UV-Ozone對氧化鎳薄膜進行表面處理，會使得薄膜內Ni２＋和Ni３＋比例產生改變，這結果不僅讓氧化鎳薄膜產生顏色上的變化，增加了光吸收，還提升了薄膜導電度，在提升元件效率上扮演了重要的角色。

In this study, we report the fabrication of poly(3-hexylthiophene):[6,6]-phenyl-C61 butyric acid methyl ester (P3HT:PCBM) OPV devices incorporating solution-based NiO interfacial layers that show promising enhancements of the device energy conversion efficiency (PCE) and lifetime.
We analyzed the size of nickel hydroxide particles, the film thickness, the surface morphology and the composition of nickel hydroxide layer By DLS, SEM , AFM, and HRXPS. The effects of the thickness of active layer, annealing temperature and the improvement of electrode on the efficiency of solar cell devices were discussed. We also compared the efficiency and lifetime of solar cell with different hole transporting layers. We conclude that the device with NiOx layer had higher efficiency and longer lifetime than the device with PEDOT:PSS .
In summary, the UV-ozone treatment causes the variation of the composition between Ni+2 and Ni+3. This consequence not only changes the color of NiOx thin-film, but rises the conductivity and optical absorption of the film. In conclusion, UV-Ozone plays an important role on the improvement of the efficiency of photovoltaic device.
