چکیده
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 efficiency of the solar cell by about 1.5%, and can also improve the quantum efficiency of the solar cell especially at shorter wavelengths. Keywords—Conversion efficiency, Graded band gap window, Quantum efficiency, Single junction AlxGa1-xAs/GaAs solar cell

In this work, we used the Atlas Tcad Silvaco software to investigate the effect of adding an additional BSF layer on the performance of InGap / GaAs dual junction solar cells with a hetero tunnel Al0.7Ga0.3As-In0.49Ga0.51P junction. These analyzes indicate that, the addition of a BSF layer to the bottom cell the increase in the thickness of the BSF top cell would reduce the recombination and in...
