“…The PV conversion efficiency increase with the increase of the electromagnetic field. There is in this study a confirmation that an electromagnetic field mainly an electric field in low values assumptions can be used to improve the outputs of the polycrystalline silicon PV cell [25,27]. The doping level affecting the outputs of the PV cell, some individual efficiencies are represented in the next paragraph.…”

The Photovoltaic (PV) system is often installed near the telecommunication antenna without takes account the performance degradation that the electromagnetic field can cause. The present work provides the recognition about the greatest losses occur which can cause the overall efficiency drop. In fact, the absorption and the thermodynamic processes are more sensitive to the variation of the electromagnetic field more than FF and thermalization processes in presence of the electromagnetic field. The absorption and thermodynamic mechanism are the main cause of the degradation of the polycrystalline silicon PV cell outputs. The PV cell having height base doping level to get a better resistivity to the electromagnetic field must be chosen to improve theses outputs. Then a low electromagnetic field zones must be searched to install the PV system improving its electrical production performance.

“…The emitter contribution will be neglected and the base of the solar cell is assumed to be the real center of all the generation phenomenon's and the recombination phenomenon's. The integration of electrical field source in PV system is presented on Figure 1 [3]. The integration of the external electrical field is the addition of other solar cells to generate the open circuit voltage.…”

“…This study proposes that for the real operation condition of a domestical PV installation, it is better to use the external load resistance smaller than the real supported capability of the PV module. The integration of an additional electric field source in the solar cell has presented an improvement under monochromatic illumination [3] and under sun light illumination [4]. These studies have shown the possibility to increase the fill factor, the conversion efficiency and others outputs of a crystalline silicon solar cell by addition of an external electrical field.…”

The state of the p-n junction is very important to explain the performances of a solar cell. Some works give the influence of the electric field on the junction capacitance. However, these works do not relate the quality of the p-n junction under the electic field. The present manuscript is about a theoretical modelling of the p-n junction capacitance behavior of the polycrystalline silicon solar cell under an integration of the external electrical field source. An external electrical source is integrated in a solar cell system. The electronic carriers charge generated in the solar cell crossed mainly the junction with the great strength external electrical field. In open circuit, this crossing of the electronic charge carriers causes the thermal heating of the p-n junction by Joule effect. The p-n junction capacitance plotted versus the junction dynamic velocity and the photo-voltage for different external electrical fields. The electric field causes the decrease of the photo-voltage mainly the open-circuit photo-voltage. The decrease of the photo-voltage translates the narrowing of the Space Charge Region (SCR). The average value of the external electric field used in this study is not sufficient to cause the breakdown of the p-n junction of the solar cell system under integration of the external electrical field production source. The increase of the electrical field causes rather the narrowing of the SCR. That can provide an improvement of the solar cell's electrical outputs.

“…The electromagnetic field from radio waves (9 kHz to 3000 GHz) [7,8] is composed of an electric field and a magnetic field which are perpendicular in the plane wave approach. The electric field causes individually the increase of the density of current produced by the PV cell [3,9]. However, the voltage provided by the PV cell decreases with the increase of the individual electric field mainly in the open circuit [3,9].…”

This manuscript is about the electric output of the silicon (Si) photovoltaic (PV) cell versus the electromagnetic field of a radio wave and a monochromatic illumination in three-dimensional (3D) assumptions. The polarisation direction of the electromagnetic wave and power density are fixed. The electromagnetic wave is provided by electromagnetic emission sources such as the telecommunication, radio, or TV antennas. A PV system is installed in the vicinity of an electromagnetic emission source. The current produced by the PV cell is sensitive to electromagnetic field increase more than the electric voltage. The electromagnetic field causes the decomposition of the current into two components which are a transferred current and a leakage current. The transferred component provides the transmitted current to the external load while the leakage component gives the loss of the carrier charge into the junction. Consequently, this decomposition of the current shares the electric power in transferred electric power and leakage electric power. The transferred electric power is obtained only in the intermediate circuit, and the maximum power point (MPP) shifts to the short circuit situation as the junction dynamic velocity becomes the greatest. However, the leakage electric power corresponds to a loss of the minority carrier’s charge in the junction during the crossing of the junction. This loss causes a Joule heating effect of the junction. The heating of the junction causes the quality degradation of the PV cell mainly due to the electric component. The solar illumination wavelength is presenting the inversion phenomenon with the maximum of the electrical outputs of the silicon PV cell of around 0.70 μm which provides the greatest conversion efficiency. This value has been chosen for the modelling of the radio wave influence. Hence, the conversion efficiency increases when the PV system is far away from the electromagnetic emission source. PV system installation in the vicinity of an electromagnetic emission source is not advised.
