The Effect of a Graded Band Gap Window on the Performance of a Single Junction AlxGa 1-xAs / GaAs Solar Cell

Abstract

We have modeled the effect of a graded band gap window on the performance of a single junction AlxGa1-xAs/GaAs solar cell. First, we study the electrical characteristics of a single junction AlxGa1-xAs/GaAs solar cell, by employing an optimized structure for this solar cell, we show that grading the band gap of the window can increase the conversion… (More)
