- Abstract: We perform the quantum yields in a multi-band quantum dot (QD) photocell via
doping an intermediate band (IB) between the conduction band (CB) and valence
band (VB). Under two different sub-band gap layouts, the output power has a
prominent enhancement than the single-band gap photocell and the achieved peak
photo-to-charge efficiency reaches to 74.9% as compared to the limit efficiency
of 63.2% via the IB approach in the theoretical solar cell prototype. The
achieved quantum yields reveal the potential to improve efficiency by some
effective theoretical approaches in the QD-IB photocell.

We investigated the fluorescence signals from Rhodamine 6G and LDS798 excited with a CW laser or an entangled photon pair source at 1060 nm.
We observed a signal that originates from hot-band absorption (HBA), which is one-photon absorption from thermally-populated vibrational levels of the ground electronic state.
For the typical conditions under which E2PEF measurements are performed, contributions from the HBA process could lead to a several orders-of-magnitude overestimate of the quantum advantage for excitation efficiency.
