초록/요약
A highly efficient luminescent solar concentrator (LSC) composed of a nanosized metal-cluster as a molecular luminophore copolymerized with poly(methyl methacrylate) (PMMA) was fabricated through a simple solution process. Organic-inorganic salts such as (dMDAEMA)(2)[Mo6Cl14] and (dMDAEMA)(2)[Mo6I14] (where dMDAEMA is 2-(methacryloyloxy)ethyl dimethyldodecylammonium) were copolymerized with PMMA to generate a highly effective, transparent, and robust LSC waveguide. This hybrid luminophore enabled the development of a highly efficient UV-vis sunlight harvesting device due to strong absorption at UV-vis wavelengths up to similar to 500 nm and a large downshift of luminescence at near-infrared wavelengths (similar to 850 nm). Si photovoltaic cells were placed at the edge of the LSC waveguide plate to collect the concentrated luminescence by internal reflection. LSCs fabricated with a 2.0 x 2.0 x 0.3 mm(3) size had the highest observed power conversion efficiency (PCE) of 1.24% and a transparency of similar to 85%, which were much higher than those of LSCs made from other luminophores with the same Si photovoltaic cell. Our LSC with chemical/physical durability, robustness, and solution processability for any desirable plate size and thickness suggests a practical future direction for smart windows of urban buildings where traditional Si photovoltaic cells cannot be directly employed.
