Abstract: We have studied the influence of the quantum-dot (QD) width and the quantum-dot conduction band (QD-CB) offset on the efficiency of quantum-dot intermediate band solar cells (QD-IBSCs). Simulation results demonstrate that with increasing QD-CB offset and decreasing QD width, the maximum efficiency is achieved.

Keywords: barrier width, efficiency, quantum-dot intermediate band solar cell, quantum dot conduction band offset, quantum-dot width.
