Abstract

This work presents a numerical investigation into the performance of a dual absorber solar cell structure employing Copper Bismuth Oxide (CuBi₂O₄) in an n/p/p⁺ configuration. CuBi₂O₄, a low-cost and environmentally friendly material, offers promising optoelectronic properties, making it a suitable candidate for thin-film photovoltaic applications. Using SCAPS-1D simulation software, the solar cell architecture was systematically optimized by varying key material and structural parameters, including layer thicknesses, doping concentrations, and defect densities. The proposed design demonstrates an impressive power conversion efficiency (PCE) of 28.13 %, with an open-circuit voltage (Voc) of 1.27 V, short-circuit current density (Jsc) of 25.58 mA/cm², and a fill factor (FF) of 85.86 %. The enhanced performance is attributed to improved charge carrier separation and reduced recombination losses at the optimized interfaces. These findings establish the potential of CuBi₂O₄ in high-efficiency, lead-free solar cell applications and provide a valuable reference for future experimental and simulation-based research.

先进n/p/p+结构CuBi2O4环保太阳能电池的建模与分析

本文对采用铜铋氧化物（CuBi2O4）在n/p/p+结构下的双吸收体太阳能电池结构的性能进行了数值研究。CuBi2O4是一种低成本、环保的材料，具有良好的光电性能，是薄膜光伏应用的合适候选者。利用SCAPS-1D仿真软件，通过改变关键材料和结构参数，包括层厚度、掺杂浓度和缺陷密度，对太阳能电池结构进行了系统优化。该设计具有令人印象深刻的功率转换效率（PCE）为28.13%，开路电压（Voc）为1.27 V，短路电流密度（Jsc）为25.58 mA/cm2，填充系数（FF）为85.86%。性能的提高主要是由于改进了载流子分离和减少了优化界面处的复合损失。这些发现奠定了CuBi2O4在高效无铅太阳能电池中的应用潜力，并为未来基于实验和模拟的研究提供了有价值的参考。
