Abstract

The energy sector is increasingly challenged to transition to sustainable and renewable energy sources. Solar cells play a pivotal role in this process, enabling the direct conversion of solar energy into electricity. Traditional solar cell models, such as the single-diode model (SDM), often assume a constant diode ideality factor, despite research indicating its dependence on voltage. This study introduces five novel SDM variants that incorporate the nonlinear dependence of the diode ideality factor on voltage, aiming to improve the accuracy of current–voltage (I-V) characteristic modeling. For each of the proposed models, an analytical current–voltage relationship was derived using the Lambert W function, ensuring precise representation of the system’s behavior. Experimental validation was conducted on a standard solar cell (RTC France) and three commercial modules (MSX60, PWP201, KC200GT), demonstrating significant reductions in modeling errors (RMSE) compared to classical SDM, DDM, and TDM approaches. Furthermore, the analysis highlights the stable performance of the proposed models under varying conditions of insolation and temperature, confirming their robustness and practical applicability. This work provides an innovative framework for enhancing solar cell modeling, laying the foundation for future research and practical applications in optimizing photovoltaic systems.

面向增强的光伏建模：具有非线性理想因子依赖的新型单二极管模型变体

能源部门在向可持续和可再生能源过渡方面面临越来越大的挑战。太阳能电池在这一过程中起着关键作用，使太阳能直接转化为电能。传统的太阳能电池模型，如单二极管模型（SDM），通常假设一个恒定的二极管理想因数，尽管研究表明其依赖于电压。本研究引入了五种新的SDM变体，这些变体结合了二极管理想因数对电压的非线性依赖，旨在提高电流-电压（I-V）特性建模的准确性。对于每个提出的模型，使用Lambert W函数推导出解析的电流-电压关系，确保系统行为的精确表示。在标准太阳能电池（RTC France）和三种商用模块（MSX60、PWP201、KC200GT）上进行了实验验证，结果表明，与传统的SDM、DDM和TDM方法相比，建模误差（RMSE）显著降低。此外，分析强调了所提出的模型在不同日照和温度条件下的稳定性能，证实了其鲁棒性和实用性。这项工作为加强太阳能电池建模提供了一个创新的框架，为优化光伏系统的未来研究和实际应用奠定了基础。
