Device analysis tool for solar cells with quantum well (QW) and quantum dot (QD) structures.
This paper introduces a demonstration of the usefulness of quantum well/quantum dot solar cells by incorporating the miniband model into the drift-diffusion theory framework. Different energies of the minibands allow for the calculation of cold carrier and hot carrier minibands. The quantum states solution of 2D quantum wells and 3D quantum dots precisely calculates the broad absorption spectrum in quantum well/quantum dot materials.
