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.

Abstract: A method for inspection for a photovoltaic module or cell is disclosed. The method includes acquiring one or more polarimetric images of the photovoltaic module or cell using a camera which may include a polarization sensor, analyzing the one or more polarimetric images, and identifying a presence of a defect in the photovoltaic module or cell. A device for inspection for a photovoltaic module or cell is also disclosed, wherein the device includes a camera having a polarimetric sensor and is configured to be positioned at one or more locations relative to a location of the photovoltaic module or cell.
