Selective Solar Absorbers: Scalable, “Dip-and-Dry” Fabrication of a Wide-Angle Plasmonic Selective Absorber for High-Efficiency Solar–Thermal Energy Conversion (Adv. Mater. 41/2017)

A simple, inexpensive, ecofriendly and scalable technique for fabricating highly efficient selective solar absorbers (SSAs) is reported by Nanfang Yu, Yuan Yang, and co-workers in article number 1702156. The technique yields SSAs with excellent wide-angle solar absorptance (≈96% at 0° and ≈79% at 70°), which is higher than, and low thermal emittance (<10%), which is on par with, those of existing designs.
