Theoretical modeling and optimization of GaAsPN/GaAs tandem dual-junction solar cells

Résumé

This paper presents an optimization and simulation of optical and electrical properties of GaAsPN/GaAs tandem Dual-Junction solar cells such as current density-voltage (J-V), external quantum efficiency (EQE), with an AM1.5 solar spectrum. We comparing the simulated performance of various N fractions and we will show that the use of N=0.01 improve the performances of external quantum efficiency (EQE) and current-voltage characteristics. Our results have been shown that an optimal efficiency of about 26.19% was obtained with P composition x=0.37 and N fractions y=0.01. In addition, a doping of 2.1018 cm-3 of the GaAs0.62P0.37N0.1 base top cell boosts the efficiency from 25.73% to 26.19%.
