Abstract

This research paper presents a comprehensive study of Cu₂O-based heterojunction solar cells, focusing on the effects of bath temperature, absorber layer thickness, and defect density on cell efficiency. Cu₂O thin films were electrochemically deposited at various bath temperatures (40–80 °C), and their structural and optical properties were investigated. Performance simulations using SCAPS software revealed that the optimal Cu₂O layer thickness is 4 μm, yielding a conversion efficiency of 12.1 %. Under optimal conditions (bath temperature 60 °C and absorber thickness 4 μm), the device achieved a simulated efficiency of 12.6 %. Results demonstrated that moderate acceptor density (10¹⁷ cm⁻³) and low defect density (10¹⁴ cm⁻³) lead to significant improvements in cell efficiency. This study provides valuable insights for developing high-efficiency Cu₂O/CdS/ZnO solar cells, emphasizing the importance of controlling deposition parameters and layer design for enhanced performance of copper oxide-based photovoltaics.

cu2o基异质结太阳能电池的实验与模拟研究：镀液温度、层厚和缺陷密度的影响

本文对cu20基异质结太阳能电池进行了全面的研究，重点研究了镀液温度、吸收层厚度和缺陷密度对电池效率的影响。在40 ~ 80℃的不同温度下电化学沉积Cu2O薄膜，并对其结构和光学性能进行了研究。利用SCAPS软件进行性能模拟表明，最佳Cu2O层厚度为4 μm，转换效率为12.1%。在最佳条件下（浴液温度60℃，吸收剂厚度4 μm），该器件的模拟效率为12.6%。结果表明，中等受体密度（1017 cm−3）和低缺陷密度（1014 cm−3）可显著提高电池效率。该研究为开发高效Cu2O/CdS/ZnO太阳能电池提供了有价值的见解，强调了控制沉积参数和层设计对提高氧化铜基光伏电池性能的重要性。

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
