Building-integrated sunlight harvesting utilizing laminated glass luminescent solar concentrators (LSCs) is proposed. By incorporating high quantum yield (>90%), NIR-emitting CuInS2/ZnS quantum dots into the polymer interlayer between two sheets of low-iron float glass, a record optical efficiency of 8.1% is demonstrated for a 10 cm × 10 cm device that transmits ∼44% visible light. After completing prototypes by attaching silicon solar cells along the perimeter of the device, the electrical power conversion efficiency was certified at 2.2% with a black background and at 2.9% using a reflective substrate. This “drop-in” LSC solution is particularly attractive because it fits within the existing glazing industry value chain with only modest changes to typical glazing products. Performance modeling predicts >1 GWh annual electricity production for a typical urban skyscraper in most major U.S. cities, enabling significant energy cost savings and potentially “net-zero” buildings.

适用于Windows的高性能CuInS 2量子点夹层玻璃发光太阳能集中器

提出了利用夹层玻璃发光太阳能集中器(LSC)进行建筑物集成的阳光收集。通过结合高量子产率(> 90%),可发射近红外光的CuInS 2/ ZnS量子点进入两片低铁浮法玻璃之间的聚合物中间层,对于透射约44%可见光的10 cm×10 cm器件,其记录的光学效率达到了创纪录的8.1%。在沿着设备的外围安装硅太阳能电池以完成原型后,在黑色背景下,电力转换效率被证明为2.2%,而在反射基板上,电力转换效率被证明为2.9%。这种“嵌入式” LSC解决方案特别有吸引力,因为它适合现有的玻璃行业价值链,仅对典型的玻璃产品进行了适度的更改。性能模型预测,在美国大多数主要城市中,典型的城市摩天大楼的年发电量将超过1 GWh,这将显着节省能源成本,并可能实现“净零”建筑。
