摘  要

中文导读:具有全光谱吸收特性的纳米流体特别适合应用于直接太阳能热转换领域,本文基于Ag和CsWO3纳米流体在可见光和近红外(NIR)区域光谱互补增强吸收特性,制备了双组分杂化纳米流体。结果表明该杂化纳米流体表现出宽带吸收特性,太阳加权吸收率达99.6%,而在同等条件下基液(乙二醇)和CsWO3纳米流体的吸收率仅为18%和54%。当Ag:CsWO3的质量比为3:7时,杂化纳米流体的光热转换效率达到67%。相对于单一组分Ag和CsWO3纳米流体,太阳能热转换效率分别提高10%和15%。双组分杂化纳米流体为太阳能的高效利用提供了一种可行的方案。 Abstract Nanofluids with full-spectrum absorption properties are highly desirable for direct solar thermal energy conversion applications. In this work, Ag and CsWO3 nanofluids, which exhibit absorption both in the visible and near-infrared (NIR) region, are integrated to obtain two-component hybrid nanofluids. The hybrid nanofluids show broad band absorption with a solar weighted absorption fraction of 99.6%, compared to 18% and 54% for the base liquid (ethylene glycol) and CsWO3 nanofluids, respectively. The highest photo-thermal conversion performance for the hybrid nanofluids is obtained with Ag/CsWO3 weight ratio of 3/7. The solar thermal conversion efficiency of the optimum hybrid nanofluids is 67%, 10% and 15% higher than single Ag and CsWO3 nanofluids. The two-component hybrid nanofluid provides an alternative for making the best use of solar energy.
