Abstract

Luminescent solar concentrators (LSCs) are promising large-scale sunlight collectors for photovoltaics due to their affordability and suitability for building-integrated photovoltaics (BIPVs). However, the low photoluminescent efficiency, narrow Stokes shift, and poor processability of most luminescent materials restrain the performance of the fabricated transparent LSCs. This work reports a copper-iodide (Cu–I) cluster-based luminescent hybrid for high-performance LSCs. This C₁₁₄H₁₀₃Cu₄I₄N₂O₂P₆ (abbreviated as CuI-1) hybrid with the ethoxy solubilizing groups shows a significant Stokes shift of 219 nm, high photoluminescence quantum yield (PLQY) of 97.9%, and excellent solubility in polar organic solvents. We fabricated the transparent CuI-1/PVP-based LSCs via facile doctor blade coating, which achieves a η_opt of 5.89% and a η_PCE of 3.04%. In addition, we developed a series of Cu–I cluster hybrids by ligand modification for LSCs, which all display excellent optical properties for LSCs. Our results show the potential of Cu–I cluster-based hybrids for high-performance LSCs in BIPV systems.

用于高效发光太阳能聚光器的高可溶性铜(I)-碘化物簇基杂化物

发光太阳能聚光器（LSCs）由于其可负担性和对建筑集成光伏（bipv）的适用性而成为有前途的大规模太阳能集热器。然而，大多数发光材料的光致发光效率低、Stokes位移窄、可加工性差，限制了制备的透明LSCs的性能。本文报道了一种用于高性能LSCs的基于Cu-I簇的发光杂化材料。加入乙氧基的C114H103Cu4I4N2O2P6（简称CuI-1）杂化产物Stokes位移达219 nm，光致发光量子产率（PLQY）高达97.9%，在极性有机溶剂中具有良好的溶解性。我们通过简易医生刀涂层制备了透明的CuI-1/ vpp基LSCs，其ηopt为5.89%，ηPCE为3.04%。此外，我们还通过配体修饰开发了一系列用于LSCs的Cu-I簇杂化物，这些杂化物均具有优异的LSCs光学性能。我们的研究结果表明，基于Cu-I簇的杂化材料在BIPV系统中具有高性能LSCs的潜力。
