The luminescent solar concentrator (LSC) has attracted worldwide attention as a sunlight manager for harvesting solar energy in building integrated photovoltaic structures. However, until now the relatively low optical efficiency (ηopt) still severely hinders the advancement of the LSCs. In this work, we report the perovskite quantum dots (QDs) integrated into the thiol-ene polymer for LSC applications. After encapsulated by the thiol-ene polymer, the CsPbBr3 QDs exhibit a slight blue-shift of the PL peak position and increasing FWHM because of the dielectric screen effect. With the different QDs' concentrations from 8.3 × 10−3  to 2.5 × 10−2 mg/ml, the LSC performance is evaluated by the direct optical characterization and the indirect photo-electrical measurement in detail. After coupling the PV cells, the as-fabricated LSC shows the optimal optical efficiency of 2.11% and the power conversion efficiency of 1.06%.

Photovoltaic integrated luminescent solar concentrators (LSCs) can be embedded in modern buildings to serve as power-generation units. In this Letter, we demonstrate and develop a Monte Carlo ray-tracing model and a numerical description for the performance and loss evaluation of LSCs based on colloidal quantum dots. The performance differences between bulk and thin-film LSCs are systematically analyzed at different sizes and concentrations. It is found that large-area thin-film LSCs generally perform better, which is attributed to the suppression of scattering and the retention of quantum yield by this structure with twice the performance of bulk LSCs.
