Abstract

Luminescent solar concentrators (LSCs) hold tremendous potential in building-integrated photovoltaic (BIPV) applications, offering a balance between electricity generation and aesthetic appeal. However, achieving LSCs with both high aesthetic appeal and excellent photo-electric performance remains a significant challenge. Herein, MAPbBr₃ (MA = CH₃NH₃) organic-inorganic hybrid perovskite quantum dots (QDs) are incorporated with the off-stoichiometric thiol-ene (OSTE) polymers to fabricate the LSCs. Benefited from the high photoluminescence quantum yield (PLQY) and low photon reabsorption losses of MAPbBr₃ QDs, the optimal edge quantum efficiency (η_edge) and internal quantum efficiency (η_int) of LSCs are 69.41 % and 21.24 %, respectively. After coupling with Si solar cells, the luminescent solar concentrator integrated photovoltaics (LSC-PV) show a high optical efficiency of 3.37 % under AM 1.5G solar illumination. In addition, the LSCs possess the excellent color rendering index (CRI) of 97.09, an average visible transmittance (AVT) of 74.47 %, and the aesthetic parameters with higher color saturation index (R_f) of 95.8 and the TM-30 color fidelity index (R_g) of 102.6, exhibiting a promising potential in BIPVs.

优化基于MAPbBr3量子点的发光太阳能聚光器，增强光电性能和美学特征

发光太阳能聚光器（LSCs）在建筑集成光伏（BIPV）应用中具有巨大的潜力，提供了发电和美观之间的平衡。然而，实现具有高美学吸引力和优异光电性能的LSCs仍然是一个重大挑战。本文将MAPbBr3 （MA = CH3NH3）有机-无机杂化钙钛矿量子点（QDs）与非化学计量硫醇烯（OSTE）聚合物结合制备LSCs。得益于MAPbBr3量子点的高光致发光量子产率（PLQY）和低光子重吸收损失，LSCs的最佳边缘量子效率（ηedge）和内部量子效率（ηint）分别为69.41%和21.24%。与硅太阳能电池耦合后，在AM 1.5G太阳光照下，发光太阳能聚光器集成光伏（LSC-PV）的光效率高达3.37%。此外，LSCs的显色指数（CRI）为97.09，平均可见光透过率（AVT）为74.47%，色彩饱和度指数（Rf）为95.8，TM-30色彩保真度指数（Rg）为102.6，具有良好的美学参数，在bipv中具有广阔的应用前景。
