A novel idea of graded band gap design in intrinsic-layer is proposed and studied numerically. We built our device model by using Matlab® coding and commercial software APSYS®. The device performance is calculated by continuity equations, and effective band gap model. The final calculation shows the optimal efficiency enhancement is about 1.32 and 2.18 times of the non-grading band gap device in GaAs and GaN system, respectively.
