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. |
