Abstract

Multijunction solar cells are champions in photovoltaic literature, exhibiting the phenomenal enhancement of efficiency in recent years. Herein, a high conversion efficiency of three different combinations of triple-junction solar cells have been investigated using an advanced version of one dimensional multijunction solar cell simulator, MSCS-1D:V2. For designing and optimizing these multijunction solar cells (MJSC), 2.17 eV AlAs and 1.9 eV bandgap GaInP₂ semiconducting material have been considered as top sub-cell, 1.42 eV bandgap GaAs as middle sub-cell, and 0.7 eV GaAs_.92Bi_.08 and 0.67 eV bandgap Ge as bottom sub-cell. These three sublayers or sub-cells of the solar cell are in lattice-matched, and this matching condition creates the facility for optical transparency. The efficiencies of the three proposed MJSC structures: GaInP₂/GaAs/Ge, AlAs/GaAs/Ge, and AlAs/GaAs/GaAs_.92Bi_.08 have been estimated as 40.3%, 45.8% and 48.3% respectively for airmass AM1.5G. The simulated efficiency of the mentioned solar cells has been compared to the experimental data published in the photovoltaic literature and found a good harmony.
