Abstract
Reflectors for concentrated solar power as well as systems and methods for additively manufacturing the reflectors is provided. The disclosed method can directly print metal films from an aqueous precursor solution onto a substrate with little to no post-fabrication treatment to achieve highly reflective surfaces with low surface roughness. The method provides precise control to form a metal film having an RMS surface roughness of about 2 to about 5 nm and a relative reflectivity of about 90% to about 96% at 550 nm on a substrate having an area of at least 1 square meter.
