摘要

A compositional grading layer between the p-In0.5Ga 0.5P emitter layer and p-In0.5Al0.5P window layer in the p +-n In0.5Ga0.5P 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.
