Silicon Nanowires for Solar Thermal Energy Harvesting
Introduction :
Silicon nanowire possesses great potential as the material for renewable energy harvesting and conversion. The
significantly reduced spectral reflectivity of silicon nanowire to visible light makes it even more attractive in solar
energy applications. However, the benefit of its use for solar thermal energy harvesting remains to be investigated
and has so far not been clearly reported.The purpose of this study is to provide practical information and insight
into the performance of silicon nanowires in solar thermal energy conversion systems.
