“…Their results confirmed that monocrystalline modules have lower temperature coefficient than polycrystalline and amorphous solar modules. Dia et al [3] studied the degradation of photovoltaic modules under tropical weather conditions. The degradation of the photovoltaic modules, due to exposure to UV radiation, temperature, humidity, and aerosols in a Sahelian environment was investigated.…”

Aside from the terrestrial magnetic field that is generated from the earth core, power transmission, and distribution lines, transformers and other equipment do produce a certain amount of magnetic field that could interfere with the performance of photovoltaic modules. This study conducted an experiment and investigated the performance of a silicon photovoltaic module subjected to a magnetic field. The current-voltage and power-voltage characteristics were plotted in the same axis system and allowed us to find, as a function of the magnetic field, the electrical parameters of the photovoltaic module such as maximum electric power, fill factor, conversion efficiency, and charge resistance at the maximum power point. These electrical parameters were then used to calculate the series and shunt resistances of the equivalent circuit of the photovoltaic module. The results have shown that the efficiency of a solar module is affected by the presence of magnetic fields. However, the magnitude of ambient magnetic field generated by power transmissions lines and other equipment is extremely low (in the order of 10−2 mT or less) as compared to the values of the magnetic field used in this study. That made it difficult to conclude as to the impact of such field on solar photovoltaic installations.

“…Their expected performance therefore is also almost never achieved. This must be added to the problems of degradation caused by their exposure to ultraviolet radiation, high temperature gradients [1,2], dust and humidity [3], etc. Furthermore, it is theoretically established that magnetic fields influence negatively the performance of PV cells and modules [4][5][6][7][8].…”

In earlier studies, we have shown theoretically and experimentally that magnetic fields (MFs) have negative impact on silicon PV module (photovoltaic module). A noticeable decline in photocurrent with a slight increase in photovoltage was observed. Also, how those fields affected other key module’s parameters was also studied. These studies concluded that an increase in the magnitude of the MF resulted in the decrease of the efficiency of the silicon PV module. The previous experimental studies assumed that the MF vector formed zero angle of inclination with respect to the photosensitive face of the module. They did not factor in any effect that could be observed when the field vector is inclined. The present experimental work is an attempt to fill that gap. The characteristic curves of the PV module were plotted in the same system of axis for different values of the inclination angle of the MF vector. Correspondingly, the characteristic values ( P max , I max , V max , I sc , and V oc ) of the PV module were also determined. These parameters then allowed the calculation of the efficiency of the module, its fill factor, and the equivalent circuit series and shunt resistances. It is observed that the module efficiency increases with the inclination of the MF vector, indicating that the effect of the MF on the PV module is reduced when its vector aligns towards a direction that is perpendicular to the base of the module. For example, when α moves from 0 to 90°, the power output and consequently the efficiency of the PV module relatively increase of 14%.

“…The performance of photovoltaic systems depends on a number of parameters such as ambient temperature, solar irradiance, sunshine duration, relative humidity, atmospheric concentrations of aerosols (harmattan dust particles for example), wind speed, wind chill and direction, rainfall, mode of installation and orientation (rooftop or ground-mounted) etc. [1,4].…”

In this work, a one dimensional approach is presented for modelling the effect of the incidence angle, varying from 0 rad to π/2 rad, and the intensity of radio waves on the performance of a polycrystalline silicon solar cell under constant multispectral illumination. By solving the continuity equation in steady state, we derived the expression of the density of excess minority carriers, the photocurrent density, the photovoltage, the electric power and their dependence on the incidence angle and the intensity of the electromagnetic field is analyzed. Using the electric power curves versus junction dynamic velocity we determined the electric power lost at the junction, the maximum electric power and we calculated the conversion efficiency for various incidence angle and intensity of the electromagnetic field. The leakage photocurrent density, deduced from the photocurrent density curves versus junction dynamic velocity, and the electric power lost at the junction allowed us to calculate the shunt resistance of the solar cell according to the incidence angle and the intensity of the electromagnetic field. The numerical data show the negative effect of radios waves on the performance of a silicon solar cell.
