Operating ranges of photovoltaic cell electrical parameters strictly depend on internal doped material structures and surfaces properties. Therefore, structure and surface are crucial issue of the research at nanostructure and atomic-charge level. The relations among electrical parameters based on well-known single-diode or double-diode models lead to exact mathematical models. Applying numerical methods, modelled result electrical parameters relations may be obtained, in stated conditions range. Often, simplifications and reduced forms of transcendental differential equations are used. But, not the only reduced differential equations system is applicable for any photovoltaic cell. In this paper, {n, R-s, R-sh, Is, I-ph} five-parameter static modelling approach is used for a small-sized general silicon photovoltaic cell. Via computer step-by-step iterative numerical modelling, the five parameters relations are computed, visualized and analyzed.
