“…The proper approach is to apply least squares techniques by taking into account the measured data over the entire experimental I-V curve and a suitable nonlinear algorithm in order to minimize the sum of the squared errors. In this section we propose a new technique that uses the measured current-voltage curve and its derivative (Chegaar et al, 2004;Nehaoua et al 2010). A non linear least squares optimization algorithm based on the Newton model is hence used to evaluate the solar cell parameters.…”

“…electrical equivalent circuit of the model Calculation of those five parameters is difficult because of the implicit form of the equation and the presence of the exponential terms. Although this equation can be solved with nonlinear optimization techniques, the accuracy of the extracted parameters depends on the type of algorithm, the objective function and the initial conditions [11][12][13]. In order to simplify the process, the parameters can be extracted by means of analytical methods.…”

Abstract. For the purpose of predict the electrical characteristics of black silicon solar cells, a simple lumped-parameter equivalent circuit model is proposed. This model is in the form of electrical equivalent circuit which contains one diode, one current source and two resistances. The model contains linear and nonlinear components. A method based on some simplifications and approximation to the nonlinear function has been proposed to estimate the model parameters. To verify the model and the method, two kinds of black silicon solar cells were used to measure the I-V curves and P-V curves at various irradiance conditions. Simulations and experiments have been conducted to confirm the operation of the proposed model and estimation method.

“…These systems require both a powerful mathematical tool and a close approximation of initial parameter values extracted by means of analytical methods to attain convergence. The least-squares numerical technique [77,90], a non-linear least-squares optimization algorithm based on the Newton method modified by introducing the so-called Levenberg parameter is the dominant vertical optimization [91]. Recently, a numerical method called APTIV as a combination of lateral and vertical methods, was used to extract the parameters of an illuminated solar cell.…”

Mobile electronic devices such as MP3, mobile phones, and wearable or implanted medical devices have already or will soon become a necessity in peoples' lives. However, the further development of these devices is restricted not only by the inconvenient charging process of the power module, but also by the soaring prices of fossil fuel and its downstream chain of electricity manipulation. In view of the huge amount of solar energy fueling the world biochemically and thermally, a carry-on electricity harvester embedded in portable devices is emerging as a most noteworthy research area and engineering practice for a cost efficient solution. Such a parasitic problem is intrinsic in the next generation portable devices. This paper is dedicated to presenting an overview of the photovoltaic strategy in the chain as a reference for researchers and practitioners committed to solving the problem.
