For intermediate band solar cells, the realization of high conversion efficiency strongly depends on the carrier two-step excitation process through intermediate levels. In this abstract, we reported on the saturable two-step photocurrent generations in an InAs quantum dot-in-well intermediate band solar cell. A mathematical model is given to reveal the carrier dynamics occurring in the intermediate states under excitations.
