Recent Advances on the Luminescent Solar Concentrator Employing Quantum Dots

The advent of quantum dots (QDs) enables us to reshape the incident light spectrum through absorption and re-emission. By exploiting the distinctive optical properties of QDs, a diverse array of optoelectronic devices that integrate QDs, including light-emitting diodes, solar cells, optical filters, and other applications, have gained widespread acceptance. Among promising applications for energy generation, luminescent solar concentrators (LSCs) exhibit remarkable potential, where QDs absorb incident solar light and re-emit it through QDs waveguides to edge-mounted solar cells. The substantial Stokes shift of QDs effectively mitigates addressed issues related to reabsorption, and the utilization of solution-processed QDs facilitates the development of low-cost LSCs. Consequently, considerable research efforts have been directed toward the development of QD-based LSCs, aiming to harness solar light more efficiently at reduced costs. This review systematically examines the potential of QD-based LSCs as a future energy solution and optical devices. It delves into the operating principles, theoretically attainable energy, materials, and optical structure developments, as well as potential applications of LSCs. Additionally, the review discusses challenges associated with QD–LSCs and outlines future research directions. We believe that this comprehensive review provides insights into the current status and prospects of LSCs employing QDs, serving as a valuable resource for researchers and professionals in the field.
