Abstract Zinc oxide and cuprous oxide thin films are environmentally friendly and low-cost semiconductors and have various optoelectronic applications. The overall cost of the heterostructures they form can also be reduced via economic fabrication methods. ZnO and Cu2O thin films can be deposit under normal laboratory conditions via spin coating and electrodeposition methods. However, the main concerns of the low-cost methods are the growth of pure Cu2O and efficient interface between the films. On the other hand, it is still worth exploiting the low-cost spin coating and electrodeposition methods due to their efficient thin film growth potential. In this study, the one-step spin coating method was employed to prepare ZnO thin films. The electrodeposition of Cu2O thin film was achieved via developed a simple two electrodes cell. The structural, morphological, optical, and electrical measurements show that p-type Cu2O thin films were successfully deposited with our system. Although the open circuit voltage of the prepared heterojunction solar cell devices is quite low, the methods here we apply and the conditions have the potential to fabricate a solar cell. Open circuit voltage and thus efficiency will increase by improving interfaces with chemical methods and more effective annealing.

用于太阳能电池应用的 ZnO/Cu2O 异质结构的制备和表征

摘要 氧化锌和氧化亚铜薄膜是一种环保、低成本的半导体，具有多种光电应用。它们形成的异质结构的总成本也可以通过经济的制造方法降低。ZnO 和 Cu2O 薄膜可以在正常实验室条件下通过旋涂和电沉积方法沉积。然而，低成本方法的主要问题是纯 Cu2O 的生长和薄膜之间的有效界面。另一方面，由于其高效的薄膜生长潜力，仍然值得开发低成本的旋涂和电沉积方法。本研究采用一步法旋涂法制备ZnO薄膜。Cu2O 薄膜的电沉积是通过开发一个简单的两电极电池实现的。结构性，形态、光学和电学测量表明，我们的系统成功沉积了 p 型 Cu2O 薄膜。虽然制备的异质结太阳能电池器件的开路电压很低，但我们在这里应用的方法和条件具有制造太阳能电池的潜力。通过改善化学方法的界面和更有效的退火，开路电压和效率将提高。
