Researchers from Los Alamos National Laboratory and the University of Milano-Bicocca have designed and synthesized a new generation of quantum dots for use in solar energy systems that overcome previous inefficiencies in harvesting sunlight. The study has been published in the journal Nature Photonics.
Quantum dots, which are nanocrystals made of semiconducting materials, appeal to scientists for use in solar photovoltaics (solar panel systems) because of their versatility and low-cost. In particular, they are desirable for use in luminescent solar concentrators (LSCs), which are photon-management devices that serve as alternatives to optics-based solar concentration systems.
LSCs are constructed from transparent materials containing emitters such as quantum dots. They concentrate solar radiation absorbed from a large area onto a significantly smaller solar cell, explains Victor Kilmov, one of the authors of the study. One exciting application of LSCs is the potential to develop photovoltaic windows, which could turn buildings into energy…
