Special Issue Information

Dear Colleagues,

The guest editor is inviting submissions to a Special Issue of Energies on the subject area of "Solar Cells, Circuits and Systems for PV Conversion". One of the most dynamically developing areas of science and technology is photovoltaics. In recent years, the efficiency of the photovoltaic effect and photovoltaic systems has been constantly increasing. In addition, the field of possible applications of photovoltaic conversion is becoming wider, e.g., photovoltaics in textronics. It is related to both the new technologies used for producing solar cells and new solutions of electronic systems participating in the process of converting electrical energy. These systems often use modern optimization algorithms and control methods. In addition, in photovoltaic systems, especially higher-power ones, it is important to store excess electricity, which results in the development of new battery technologies or the use of components such as supercapacitors.

This Special Issue will deal with the latest technologies related to the production of photovoltaic cells and testing the properties of PV cells, innovative electronic energy conversion systems ensuring a high efficiency when converting dc to ac and dc to dc energy used in photovoltaic systems, e.g., in inverters, methods of modeling cells, devices and photovoltaic systems, and technologies of energy storage obtained in PV systems. The presented topic of this Special Issue can also be extended to other interesting research areas related to the photovoltaic conversion of energy.

In this paper, the explicit equation of the single diode model (SDM) expressed by the Lambert W function was reduced to its simplified form through variable replacement; then the simplified explicit equation was combined with an intelligent optimization algorithm to estimate the SDM parameters of solar cells and PV modules. To evaluate the parameter extraction performance of the new method, eight typical intelligent optimization algorithms were combined with the implicit, explicit, and simplified explicit equation to extract the SDM parameters of a solar cell and three types of PV modules. The results show that the new method not only improves the accuracy of parameter extraction but also enhances the robustness and convergence speed. Most importantly, the new method can nearly improve the parameter extraction accuracy of a poor-performing algorithm in traditional methods to the level of other well-performing algorithms without enhancing the algorithm itself. In a word, this study offers a new choice for a more accurate and reliable extraction of SDM parameters from both solar cells and PV modules. Full article

Irradiance variability is one of the main challenges for using photovoltaic energy. This variability affects the operation of maximum power point trackers (MPPT) causing energy losses. The logic of the Perturb-and-Observe MPPT algorithm is particularly sensitive to quick irradiance changes. We quantified the existing relation between irradiance variations and efficiency loss of the logic of the Perturb-and-Observe MPPT algorithm, along with the sensitivity of the MPPT to its control parameters. If the algorithm parameters are not tuned properly, its efficiency will drop to nearly 2%. Irradiance variability causes a systematic energy loss of the algorithm that can only be quantified by ignoring the hardware components. With this, we aim to improve the energy yield estimation by providing an additional efficiency loss to be considered in the calculations. Full article
