Three Dimensional Study of Spectral Response of Polycrystalline Silicon Solar Cells: Vertical Junction Frequency Modulation Scheme

摘要

In this paper, the modeling of a bifacial polycrystalline silicon solar cells vertical junction is presented. The study in dynamic frequency is limited to wavelengths from 400 nm to 1100 nm. The dependence of solar cell spectral response on wavelengths for several modulation frequencies was evaluated by using solar cell internal quantum efficiency. The objective is to characterize the polycrystalline silicon in 3D. The effect of frequency modulation pulsation on the phase of internal quantum efficiency was presented as well as values of shunt and series resistance for various grains size values. The results show that the value of maximum internal quantum efficiency is about 50% with a wavelength of 0.82 nm and a frequency of 10~3 rad/s under monochromatic illumination.
