The paper represents the mathematical model for diagnostics of solar cell. The research objectives are the problem of determining a solar cell technical condition during its operation. The solar cell diagnostics is based on the mathematical model of solar cells. The single-diode solar cell model is characterized by a slight deviation of the theoretically calculated characteristics from the characteristics of the real solar cell, one of the reasons being the complexity of the accurate measurement of the series resistance. The single-diode solar cell model uses the current and voltage ratio in the form of an implicit function and it cannot be solved directly. For its solution it is necessary to use numerical methods. This is main disadvantage of the single-diode solar cell model. The methodological approach to increasing the reliability of the solar cell diagnostic has been proposed, in terms of multi-parameter the solar cell diagnostic by applying the solar cell impedance model.

“…In order to ascertain the theoretical basis of research question 2, prior to the experimental and the simulation assessments, an approximate analysis can be offered through a lumped impedance representation of the cases involving localised versus longer electrodes. It has generally been shown that the impedance of different tissue layers can be approximately represented by simplified lumped impedance models [24], [25], [26]with impedance magnitudes at the applied frequency considered. Following the geometric model presented previously, and assuming θ = 0, Fig.…”
