本研究以較簡易的電化學沉積法製備N型氧化亞銅薄膜於玻璃基板ITO上，並透過最佳化其熱處理的溫度(大氣環境下100oC持溫一個小時)以改善材料之結晶結構，成功將試片的光電流密度由1.9 mAcm-2提升至2.1 mAcm-2 。
另一部分則是藉由在N型氧化亞銅材料中進行高價數陽離子的鎳參雜來部份取代掉些許一價的亞銅離子以期能提升該材料整體之載子濃度以降低電阻提升光電流。在分別測試了0.25mM、0.5mM、1mM、2.5mM四種鎳參雜濃度後，發現於0.5mM的參雜濃度下，有最高的光電流密度2.4 mAcm-2。
本論文由兩種不同的方式提升N型氧化亞銅的光電流密度，均獲得不錯的實驗結果，其證明N型氧化亞銅仍是一種具有潛力的產氫材料，在電化學領域上擁有不錯的研究成果。

The synthesis of n-type Cu2O films for photoelectrochemical (PEC) water splitting were proposed by means of electrochemical deposition route on the indium tin oxide (ITO). The films were then to be annealed in ambient environment for one hour to enhance the crystal structure of the cuprous oxide. This benefit promotes its light current density from 1.9 mAcm-2 to 2.1 mAcm-2.
On the other hand, doping high-valance cations such as Nickel in the n-type cuprous oxide is another way to enhance the overall carrier concentration. Some of the Nickel cations replace Cu(I) cations in the cuprous oxide was expected. 0.25mM, 0.5mM, 1mM, and 2.5mM Nickel doping was tested, respectively. The result shows that 0.5mM Ni-doped cuprous oxide can perform highest light current density, which is 2.4 mAcm-2.
This research provides two different directions to enhance the n-type cuprous oxide, the results from the two parts show the proposed strategy enhances the PEC performance as achieved by electrochemical deposition is highly promising for use in producing inexpensive and environmental friendly solar devices.
