Gradient-based and multi-innovation gradient-based iterative algorithms for single-diode photovoltaic cell models

第37届中国控制会议

作者： Mei Qin Yu Institute of Automation Hangzhou Dianzi University

In order to solve the problem of low parameter identification precision in photovoltaic parameter identification, a photovoltaic cell parameter identification algorithm（PGN） based on Perturbation and Observation and modified Gauss-Newton method is proposed based on the single diode model of photovoltaic cells. The algorithm uses the extreme conditions at the maximum power point to change the original nonlinear equations into an augmented equation set, reducing the number of test points and reducing the computational complexity. And on the basis of the Gauss-Newton method, by adding one dimension search condition, the probability of the target value rising with the iteration is greatly reduced. Experiment and analysis shows that: The accuracy of the proposed algorithm is significantly higher than that of particle swarm optimization, pattern search algorithm, simulated annealing algorithm, genetic algorithm and Gauss-Newton algorithm. It provides a new method for photovoltaic cell performance parameter detection.

This study presents the parameter estimation of single diode photovoltaic cell models. To identify parameters more simply and effectively, a gradient-based iterative identification algorithm and a multi-innovation gradient-based iterative identification algorithm are proposed for single-diode photovoltaic cell models by using the negative gradient search and the multiinnovation identification theory. Finally, the scheme is analyzed through a large number of statistical analysis results, and it shows the effectiveness of the proposed algorithms.

A type of photovoltaic cell was made by sandwiching micro-crystalline chlorophyll-a (chla) layer and polyvinyl alcohol (PVA) film between two semiconductive optical transparent SnO2 electrodes, such as SnO2/chla/PVA/SnO2. The cell showed a dark rectifying effect and presented photovoltaic properties on illumination, which was illustrated by the charge distribution in the cell. It was suggested mat the SnO2/chla junction might be responsible for photovoltage and the chla/ PVA for the charge separation upon irradiation of visible light. The equivalent electric circuit was discussed and its equivalent component values were calculated.

1 Results Polymer photovoltaic cells, which provide clean and renewable energy sources, have gained more and more attention. Polymer photovoltaic cells have the advantage of low fabrication cost and high mechanical flexibility. Polymers can be processed through a solution process, so that a homogeneous polymer film could be readily prepared in a large area. Recently, the light-to-electricity conversion efficiency of the polymer photovoltaic cells was improved significantly[1-2]. Polymer donor and organi...

Recent work demonstrated that efficient solar-energy conversion could be achieved in polymer photovoltaic cells (PVCs) based on interpenetrating bi-continuous networks([1,2]). In this paper we present a comprehensive study on improving energy conversion efficiencies of PVCs based on composite films of MEBPPV and fullerene derivatives. Carrier collection efficiency of ca. 30% el/ph and energy conversion efficiency of 3.9% were achieved at 500 nm. At reverse bias of 15 V, the photosensitivity reached 0.8 A/W, corresponding to a quantum efficiency over 100% el/ph. These results suggest that high efficiency photoelectric conversion can be achieved in polymer devices with M-P-M structure. These devices are promising for practical applications such as plastic solar cells and plastic photodetectors.

The improvement of the performance of organic photovoltaic cells (OPVCs) and the photogeneration process in these devices may occur via multiple mechanisms depending on their structure and/or architecture. For this purpose we investigate how self-assembled monolayers of thiol molecules (C12H25SH and 3T(CH2)6SH) and benzoic acid molecules (ABA and NBA) affect the efficiency and the photogeneration of free carriers in a sexithiophene based photovoltaic cells. Firstly, we provide the results of absorption spectra for samples with SAM of thiol that show there effect on orientation of 6T molecules on these structures and the organization degree of the thiol molecules on ITO substrate. Afterward, we describe from current vs. applied voltage after illumination, the enhancement of the performance of these cells. In the second, we study the effect of SAM of benzoic acids molecules on the photovoltaic behavior. A theoretical model is used for quantitative description of the open circuit voltage as a function of carrier’s generation rates at the electrodes. The results of I-V characterization under illumination show that open circuit voltage as well as short circuit current is dramatically affected by the dipolar layer. The orientation and the magnitude of dipole moment of benzoic acid molecules are the crucial factors that affect the organic photovoltaic parameters.
