EFFICIENCY OPTIMIZATION IN A RAINBOW QUANTUM DOT SOLAR CELL

In this paper, we have calculated the efficiency and I-V characteristic of a Quantum Dot (QD) Solar Cell (SC) based on multi-stacked different-sized InGaN QDs on GaN substrate. In order to engineering the confinement states of QDs, we have inserted differentsized QDs in i-region of a p-i-n structure which includes different layers. This leads to Rainbow SCs.
