Abstract

The electronic structure of the self-assembled quantum dot is presented in this paper to explore the efficient design of quantum dot solar cell. The electronic states of InAs quantum dot embedded in a GaAs matrix have been studied in this article, in which it is assumed the effective mass is independent of level energy for simplification. The shape effect and the layer effect for single quantum dot are investigated, and a simple one-band model for array quantum dots is studied. In the array quantum dots the wave function interaction will be strong, when the space between quantum dots is very close, which will affect the level energy.
