Quantum dot assisted luminescent hexarhenium cluster dye for a transparent luminescent solar concentrator

Abstract A luminescent solar concentrator (LSC) is a solar-light harvesting device that concentrates light on photovoltaic cell placed at the edge of an LSC panel to convert it into electricity. The nano-sized inorganic–organic cluster complex (dMDAEMA) 4 [Re 6 S 8 (NCS) ] (this refers RMC where dMDAEMA 2-dimethyl amino ethyl methacrylate) promising candidate for luminophores due its downshifted broad photoluminescence suitable cells. However, low quantum yield (QY) limits performance. Here, zinc-doped CuGaS/ZnS core/shell dots (ZQD) were used as energy transferring donor with high QY improve performance LSC. two metal chalcogenide luminophores, and ZQD, are chemically dispersion in amphiphilic polymer matrix, producing transparent waveguide suppressed reabsorption extended coverage spectrum. We achieved η opt 3.47% PCE 1.23% while maintaining greater than 80% transparency visible range. this dual-dye reabsorption, scattering losses not only uniform dyes but also transfer from ZQD RMC. This report suggests new possibility various multi-dye LSCs use building-integrated windows.
