Abstract: A compositional grading layer between the
p-In Ga P emitter layer and p-In Al P window layer
in the p -n In Ga P solar cell is investigated numerically.
With the insertion of the grading layer, the short-circuit current
density and conversion efficiency are improved due to the enhancement
of carrier-collection efficiency, which can be ascribed
to the reduction of potential barrier height in the valance band
and the existence of internal quasi-electric field in the conduction
band. An optimized value of conversion efficiency can be obtained
by appropriately adjusting the thickness of the grading layer.
