They interact or “talk” with one another in a way that lets them selectively pick and emit only the photons with the right energy. These photons are then sent to the photovoltaic (PV) cells, where they can be converted into electricity.
“This selective emission, achieved through insights from quantum physics, maximizes energy conversion and allows for higher efficiencies than previously possible,” the study authors note.
Using the quantum effects, the resonators are able to control photons released at the quantum level, ensuring that only the most useful photons for the photovoltaic (PV) cell are emitted, improving the overall efficiency of the system.
