Abstract

Luminescent solar concentrators (LSCs) can harvest diffuse sunlight over large areas and guide it to small edge-mounted photovoltaic cells, enabling building-integrated photovoltaics. We report CsPbBr₁.₅I₁.₅ perovskite quantum dots (PQDs) encapsulated in a UV-cured polymer matrix achieving a record 8.1% optical power efficiency for a 400 cm² LSC panel. The large Stokes shift (108 nm) minimizes reabsorption losses, while silica-shell passivation extends operational stability to over 3,000 hours under 1-sun illumination. Ray-tracing simulations validated by experimental data project 6.2% system efficiency when coupled with GaAs micro-cells.
