“…The presence of the series resistance R represents the sum of several structural resistances of the device (Soon et al, 2014;Boutana et al, 2017), including the parasitic series resistance (Mazhari, 2006) and dissipative effects (Cuce et al, 2017), the contact resistance of the metal base with the p semiconductor layer, the resistances of the p and n bodies, the contact resistance of the n layer with the top metal grid (Chin et al, 2015;Cibira and Koscová, 2014), and the resistance of the grid (Khan et al, 2013;Lasnier and Ang, 1990), and finally, the resistance of the materials which compose the module and causes a reduction on the power converted by this device (Ruschel et al, 2016).…”

“…However, its facility results in loss of accuracy, thus, it is important to identify and discuss the main assumptions made by the models. Chaibi et al (2018), Cibira and Koscová (2014) and Lineykin et al (2014) assumed that the band gap is constant in function of temperature variation. This assumption brings not just loss of accuracy, but it gets away of reality.…”

“…The use of lambert W-function is adopted by Cibira and Koscová (2014) 0, Lineykin et al, 2014, Peng et al (2014. This method reduces the time-consuming since it was developed to solve exponential equations since it can be seen as the inverse function of .…”

Over the years, the contribution of photovoltaic energy to an eco-friendly world is continually increasing. Photovoltaic (PV) cells are commonly modelled as circuits, so finding the appropriate circuit model parameters of PV cells is crucial for performance evaluation, control, efficiency computations and maximum power point tracking of solar PV systems. The problem of finding circuit model of solar PV cells is referred to as “PV cell equivalent model problem”. In this paper, the existing research works on PV cell model parameter estimation problem are classified according to error quali-quantitative analysis, number of parameters, translation equations and PV technology. The existent models were discussed pointing out its different levels of approximation. A qualitative comparative ranking was made and four models were found to be the best ones for simulating PV cells. Besides, based on the conducted review, some recommendations for future research are provided.

When measuring optical parameters of a photovoltaic silicon cell, precise results bring good electrical parameters estimation, applying well-known physical-mathematical models. Nevertheless, considerable re-combination phenomena might occur in both surface and intrinsic thin layers within novel materials. Moreover, rear contact surface parameters may influence close-area re-combination phenomena, too. Therefore, the only precise electrical measurement approach is to prove assumed cell electrical parameters. Based on theoretical approach with respect to experiments, this paper analyses problems within measurement procedures and equipment used for electrical parameters acquisition within a photovoltaic silicon cell, as a case study. Statistical appraisal quality is contributed.

“…However, methods for finding the model parameters in the case of instantaneous variations in the temperature and irradiance have not been considered. In [ 15 ], a PV model was built upon simple procedures to acquire the PV system parameters in an easy and fast manner. This model was used mainly to characterize these parameters by using MATLAB/ Simulink.…”

A grid-connected photovoltaic (PV) system operates under fluctuated weather condition has been modeled and characterized based on specific test bed. A mathematical model of a small-scale PV system has been developed mainly for residential usage, and the potential results have been simulated. The proposed PV model based on three PV parameters, which are the photocurrent, IL, the reverse diode saturation current, Io, the ideality factor of diode, n. Accuracy of the proposed model and its parameters evaluated based on different benchmarks. The results showed that the proposed model fitting the experimental results with high accuracy compare to the other models, as well as the I-V characteristic curve. The results of this study can be considered valuable in terms of the installation of a grid-connected PV system in fluctuated climatic conditions.
