摘要

本研究基于实验验证的设计,提出了具有n-i-p结构(FTO/TiO2/MAPbI3/HTM)的钙钛矿太阳能电池(PSCs)的创新分析模型。与传统方法不同,我们的工作在数值模拟、实验数据和分析建模之间建立了三重比较,从而实现了严格的交叉验证。首先,我们使用Silvaco软件对结构进行了再现,并提取了短路电流密度(JSC)为22.057 mA/cm2、开路电压(VOC)为1.15 V、功率转换效率(PCE)为12.68%、填充系数(FF)为50.03%等关键参数,与实验结果吻合良好。其次,建立了基于连续性方程的解析模型,考虑了界面条件、内部电场和载流子产生曲线。该模型在MATLAB中实现,可以通过结合光生电流和暗电流来绘制J-V曲线。该曲线便于提取关键参数,其中JSC为22.82 mA/cm2, VOC为1.1147 V, PCE为12.74%,表明实验数据与Silvaco程序仿真和分析模型之间具有较高的兼容性。通过模型模拟改变钙钛矿层厚度(约0.26 ~ 0.35 μm),我们观察到相应的PCE变化为15.678% (0.35 μm)。本工作不仅证明了该分析模型与Silvaco仿真和实验数据的一致性,而且还评估了其在优化PSC性能和设计方面的实用性。

Comprehensive analytical modeling of perovskite (MAPbI3) solar cells: A rigorous validation via simulations and experiments
This study proposes an innovative analytical model for perovskite solar cells (PSCs) with an n-i-p structure (FTO/TiO2/MAPbI3/HTM), based on an experimentally validated design. Unlike conventional approaches, our work establishes a triple comparison between numerical simulation, experimental data and analytical modeling, which enables rigorous cross-validation. First, we used Silvaco software to reproduce the structure and extract key parameters such as a short-circuit current density (JSC) of 22.057 mA/cm2, an open-circuit voltage (VOC) of 1.15 V, a power conversion efficiency (PCE) of 12.68%, and a fill factor (FF) of 50.03%, all in good agreement with the experimental results. Next, an analytical model based on the continuity equation was developed, incorporating interface conditions, the internal electric field, and the carrier generation profile. This model, implemented in MATLAB, allows the J-V curve to be plotted by combining the photogenerated and dark currents. This curve facilitates the extraction of key parameters, including JSC of 22.82 mA/cm2, VOC of 1.1147 V and a PCE of 12.74%, which shows a high compatibility between experimental data, the Silvaco program simulation and the analytical model. By varying the thickness of the perovskite layer through the model simulations (around 0.26 to 0.35 μm), we observed a corresponding variation in the PCE of 15.678% (0.35 μm). This work not only demonstrates that the analytical model is consistent with the Silvaco simulation and experimental data, but also evaluates its utility for optimizing the performance and design of PSC.
