Abstract

This article examines and investigates the best both fraction of indium and critical depth of a tandem photovoltaic (PV) cell single junction in the vein to optimize it electrical efficiency. For better investigation, the optical and electronics parameters of a solar cell are determined in terms of both fraction of indium and it depth, leading to the resolution of the continuity equation and the establishment of the electrical characteristics (short circuit photocurrent, open circuit photovoltage, maximum electric power). Outlet of our numerical investigations conducted in the standard test conditions in the bandwidth of visible spectrum of the irradiation, we have found that the best both fraction of indium and depth of the solar cell at the optimum electric power point are x=0.6 and H=1 micrometer respectively. Furthermore under normalized irradiation condition , we found a maximum electric power and efficiency of about 28.53mW/cm2 and 28.53% respectively.
