Luminescent solar concentrators (LSCs) are effective large-area sunlight collectors that use cells to convert focused into electricity based on the emissive fluorophores. However, development of high-performance LSCs still remains a challenge. In this work, fabricated by incorporating CdSe/ZnS core-shell quantum dots (QDs) and Au nanoparticles (NPs) off-stoichiometric thiol-ene (OSTE) polymer. The light absorption efficiency photoluminescence (PL) intensity QDs significantly enhanced localized surface plasmon resonance (LSPR) effect NPs. When concentration NPs is 2 ppm, maximal internal ( η int ) external ext measured be 9.90% 3.85%, respectively. Compared control devices, increases 1.78-fold in 2.97-fold achieved. addition, power conversion (PCE) optical opt show 0.49 times 0.35 times, Furthermore, LSC with ppm possesses excellent aesthetic parameters color rendering index (CRI) 92.11 an average visible transmission (AVT) 75.02%. Therefore, optimal will shed high-efficiency superior meet demands practical applications.
