Abstract

This study presents a machine learning-based design framework utilizing deep Q-learning (DQL) to optimize ultra-thin CdTe solar cells with active layer thicknesses ranging from 100 to 400 nm. By coupling the transfer matrix method for optical analysis with SCAPS-1D simulations for electrical modeling, the DQL agent effectively explored the complex parameter space, optimizing the thicknesses of all key layers, including SnO2, CdS, CdTe, MoO3, and Au. The DQL framework intelligently adjusted each layer based on electromagnetic wave propagation and absorption profiles, enhancing internal reflection and light trapping within sub-micron geometries. Even at extremely low absorber thicknesses (e.g., 100 nm), the optimized structures achieved high photovoltaic performance, with power conversion efficiencies up to 9.39% and Jsc values exceeding 11 mA/cm2. At 400 nm, efficiency increased to 15.75% with Jsc of 20.86 mA/cm2. These results demonstrate that efficient photon harvesting and carrier transport are achievable through full-stack optimization. External quantum efficiency and absorption spectra confirmed the integrated optical-electrical enhancement achieved by DQL. This work highlights the capabilities of reinforcement learning in high-dimensional solar cell design problems and provides a scalable approach for developing next-generation, lightweight, efficient, and material-conscious photovoltaic technologies.

机器学习辅助的新型光伏优化定制超薄碲基太阳能电池
本研究提出了一种基于机器学习的设计框架,利用深度q -学习(DQL)来优化活性层厚度从100到400纳米的超薄碲化镉太阳能电池。通过将光学分析的传递矩阵法与电建模的SCAPS-1D模拟相结合,DQL代理有效地探索了复杂参数空间,优化了包括SnO2、CdS、CdTe、MoO3和Au在内的所有关键层的厚度。DQL框架基于电磁波传播和吸收剖面智能调整每层,增强亚微米几何形状的内部反射和光捕获。即使在极低的吸收剂厚度(例如100 nm)下,优化后的结构也实现了很高的光伏性能,功率转换效率高达9.39%,Jsc值超过11 mA/cm2。在400 nm时,效率提高到15.75%,Jsc为20.86 mA/cm2。这些结果表明,通过全栈优化可以实现高效的光子捕获和载流子输运。外部量子效率和吸收光谱证实了DQL实现的集成光电增强。这项工作强调了强化学习在高维太阳能电池设计问题中的能力,并为开发下一代轻质、高效和材料意识光伏技术提供了一种可扩展的方法。
