A theoretical study of radio wave attenuation through a polycrystalline siliconsolar cell

Özet

One-dimensional study of both electronic and electrical parameters of a silicon solar cell in the presence ornot of an electric eld, a magnetic eld, or an electromagnetic eld does not take into account the grain size and thegrain boundary recombination velocity. A three-dimensional study, on the contrary, takes those factors into account.However, the three-dimensional study poses the problem of the attenuation of the wave in the grain of the polycrystallinesolar cell as well as the issue of nding the expressions of its components. This study aimed to solve these issues byconsidering radio waves, which are becoming more and more present in our environment via telecommunication masts.We rst obtained the expressions of both the electric eld and magnetic eld in a grain of a polycrystalline silicon solarcell by solving the dispersion equation. Then we investigated the evolution of the radio wave into the grain by analyzingthe behavior of the exponential coefficient that appeared in the expressions of both the electric eld and the magnetic eld. The study has shown that the attenuation of the radio wave can be neglected through the polycrystalline siliconsolar grain and by extension through the polycrystalline silicon solar cell.
