- Abstract: Revealing the quantum regime of photovoltaics is crucial to enhancing the
internal quantum efficiency of a double quantum dots (DQDs) photocell housed in
a cavity. In this study, the performance of a quantum photovoltaic is evaluated
based on the current-voltage and power-voltage characteristics in a
cavity-coupled DQDs photocell. The results show that the cavity-DQDs coupling
coefficient plays a dissipative role in the photovoltaic performance, and the
cavity has a limited size for the photovoltaic performance. Additionally, more
low-energy photons are easily absorbed by this cavity-coupled DQDs photocell
compared with the case without cavity. These results may provide some
strategies for improving the photoelectric conversion efficiency and internal
quantum efficiency of cavity-coupled DQDs photocells.
