Description:
Ga 1-x In x P composition has been applied to the top cell of multi-junction GaInP/GaAs based solar cell and currently have achieving a conversion efficiency of more than 46%, however its capability is unclear. We performed an analysis using Silvaco simulation method to evaluate the effect of In and the substitution was made to the Ga 1-x In x P for the range of x from 0 to 1. We found that the highest efficiency recorded was 17.66% when the composition of Indium was x=1. The efficiency has been increasing about 11.71% from x=0 to x=1 In content. As the composition of In raised, the value of efficiency and short circuit current density, Jsc also become higher (13.60 mA/cm 2 ) by having a greater photon absorption in a wider band gap energy. In addition to that, V oc , P max , V max , I max and fill factor was measured to be 2.15 V, 2.44 mW/cm 2 , 2.0 V, 1.22 mA/cm 2 and 83.34 res...
