Demonstrating the Simultaneous Effect of Base Heating and External Electric Field on PV Cell Performance under Intense Illumination | Chapter 3 | Scientific Research, New Technologies and Applications Vol. 8

The characterization of the performances of a PV cell is linked to the intrinsic factors of this cell. It is therefore important for us to identify the favorable or unfavorable conditions that affect the performance of PV cells. It is from this perspective that it seems judicious to us to study the simultaneous influence of the heating of the base and an external electric field on the performance of a PV cell under intense illumination of 50 suns. The importance of this research is that it provides the scientific community with results that can promote the development of more efficient photovoltaic cells and improve the conversion of solar energy. Two phenomena contribute to the heating of the base of a PV cell which are heating due to the transfer by conduction of solar radiation energy received by the surface of the PV cell and the heat generated inside the PV cell by various phenomena linked to the movement of photogenerated charged carriers. In this study, we take into account the heating linked to the movement of the charged carriers in the base. Based on mathematical modelling taking into account the concentration gradient electric field and the variable external electric field, some hypotheses are formulated and the expressions of the electrical parameters are established as a function of the electric field and base temperature. Subsequently, we use numerical simulation to highlight the behavior of theses parameters as a function of temperature and of the intensity of the electric field.  The results show that for any given temperature, the orientation of the electric field as considered in our work improves the performance of the PV cell while high temperatures degrade these performances. Furthermore, the analysis of the curves shows that the harmful effect of temperature on the performance of a PV cell is more accentuated at large values of electric field. In addition, these results recommend cooling the photovoltaic cells using heat transfer fluid and a very precise orientation of the electric field for better performance.
