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 C 114 H 103 Cu 4 I 4 N 2 O 2 P 6 (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.
