Influence of electromagnetic waves produced by an amplitude modulation radio antenna on the electric power delivered by a silicon solar cell

Abstract

This article presents a one dimensional modeling of the influence of electromagnetic waves on the electric power delivered by a silicon solar cell under monochromatic illumination in steady state. The electromagnetic waves are produced by an amplitude modulation radio antenna of 2MW power of radiation and located at a variable distance of the solar cell [ [ +∞ , m 10. The magnetotransport and continuity equations of excess minority carriers are solved with boundary conditions and led to new analytical expressions of minority carrier's density, photocurrent density, photovoltage and electric power depending on electromagnetic field intensity and wavelength λ. The dependence of the electromagnetic field and the incident light wavelength on photocurrent density, photovoltage and electric power is studied. The intensity of the electromagnetic field depends on the distance between the solar cell and the amplitude modulation radio antenna. We determine the peak power and the operating point of the solar cell according to distance or electromagnetic field intensity and also according to the wavelength of the monochromatic light.

Effect of Incidence Angle Varying from 0 rad to π/2 rad and Intensity of Radio Waves on the Performance of a Silicon Solar Cell

“…A comparative study of the influence of electromagnetic field coming from AM and FM radio antennas on the power output and conversion efficiency of a silicon solar cell has been conducted by Zerbo et al [11]. For a given type of radio antenna, they obtained the same conclusion as for previous studies [9,10] but their study revealed that the FM radio antennas which produce low values of electromagnetic field have less influence on the solar cell than AM radio antennas.…”

“…They also observed an increase of the short-circuit photocurrent density and the leakage photocurrent density but a decrease of the open circuit voltage. In a related study, Zerbo et al [9] studied the effect radio waves on the power output and conversion efficiency of a silicon solar cell. The study conditions were same as in [10], except that this time the cells were illuminated by monochromatic light.…”

“…In their studies, Zerbo et al [9][10][11], did not take into account the leakage photocurrent density and the related electric power to calculate the shunt resistance of solar cells exposed to radio waves.…”

“…• the solar cell is submitted to the action of a plane progressive monochromatic waves linearly polarized and propagating in the sense of the increasing z [9][10][11].…”

“…• the origin of space and time is chosen at the moment when the electromagnetic waves meet the solar cell [9][10][11].…”
