Performance degradation is still a challenge for the development of conventional polymer luminescent solar concentrator (LSC). Liquid LSC (L-LSC) may be an alternative due to polymerization-free fabrication. Here, we have prepared a CsPbBr3 quantum dots (QDs)-based L-LSC by injecting the QDs solution into a self-assembly quartz glass mold. The as-fabricated L-LSC performance is evaluated by optical characterization and photo-electrical measurement. The external quantum efficiency of the L-LSC is up to 13.44%. After coupling the commercial...
