Double quantum dot solar cell

الملخص EN

Double quantum dot solar cell system was modeled and studied by couplingthe minority carrier-continuity equation with the density matrix theory.

This makes it possible to take into account the contribution from groundstate in quantum dot (QD) in addition to wetting layer (WL) and barrier.

Thecontribution of different rates and the quantum efficiency are examined.

Itis shown that the highest rate was that from barrier-to-WL in the conductionband, thus, to get high QE one needs that this rate was high.
