Computational Investigation of InxGa1−xN/InN Quantum-Dot Intermediate-Band Solar Cell
-
Abstract
An InxGa1−xN/InN quantum-dot intermediate-band solar cell is calculated by means of solving the Schrödinger equation according to the Kronig–Penney model. Based on particular assumptions, the power conversion efficiency is worked out. The results reveal that the InxGa1−xN/InN quantum-dot intermediate-band solar cell manifests much larger power conversion efficiency than that of p-n junction solar cells, and the power conversion efficiency strongly depends on the size of the quantum dot and the interdot distance. -
