Abstract

Harvesting solar radiation should be improved to make this type of renewable energy more competitive in economic terms. Furthermore, to develop "green" nanotechnology is a prerequisite for crossing the boundary between research and industrial applications. In this contribution we will show the synthesis of a solar nanofluid of tin with ethylene glycol by pulsed laser ablation in liquids, a green and sustainable method for nanoparticles production. We will demonstrate that the nanofluid obtained with this technology is more stable that the one synthesized by conventional chemistry and have a reduced solar irradiance transmission through the time.
