摘要：

We propose analytically and demonstrate experimentally that an ensemble of silicon nanoparticles with different sizes can effectively absorb sunlight. Due to the extinction of silicon from UV to near-infrared region, Mie resonances in silicon nanoparticles dramatically enhance the absorption of solar light. In experiment, silicon nanoparticles dispersed in water worked as excellent sunlight-heat transducers that efficiently harvest sunlight to accelerate heating and vaporization of water by nanoscale local heating. Our study opens up the potential of silicon nanoparticles in various solar-thermal applications. (C) 2016 Optical Society of America
