光伏电池片等效物理模型参数辨识及其光谱响应估算研究
Parameter identification and spectral response estimation of equivalent physical model of solar cells
摘要
Abstract
In order to comprehensively evaluate the power generation performance of solar cells,aiming at solving the problem that the existing photovoltaic(PV)equivalent circuit model cannot estimate its spectral response characteristics,in this paper,an equivalent physical model of solar cells and its parameter identification method based on the finite element method is proposed to estimate its electrical characteristics and spectral response.Firstly,the influence of key parameters in the finite element model on the estimation results of electrical characteristics is analyzed.Six parameters,including the thickness of the emitter region,the thickness of the base region,the doping concentration of the emitter region,the doping concentration of the base region,the series resistance,and the parallel resistance,are determined as the model parameter identification objects.Then,based on the measured current-voltage(Ⅰ-Ⅴ)characteristic data under high irradiation conditions,the particle swarm optimization algorithm is used to identify the above parameters.Finally,the Ⅰ-Ⅴ characteristics under different irradiation and temperature conditions are measured and compared with the model estimation results.Meanwhile,the solar spectrum curves are measured to indirectly verify the accuracy of the spectral response of the solar cell estimated by the model.The experimental results show that the root mean square error(RMSE)of the estimated current for mono-Si and poly-Si cell models are in the range of 0.019 2 A to 0.030 2 A and 0.018 0 A to 0.051 5 A,respectively.The absolute percentage error between the estimated short-circuit current and the measured short-circuit current is concentrated below 15％.The proposed equivalent physical model of solar cell and corresponding parameter identification method can comprehensively reflect its actual performance.关键词
