Abstract: The present invention is directed to luminescent solar concentrators, processes for the production of the same and uses thereof. The luminescent solar concentrators comprise a composite substrate including two or more films containing luminescent compounds and wavelength-selective mirrors, which concentrators may be connected to photovoltaic cells.

Abstract: Provided is a substrate having a surface that is at least partially laminated with a coating that provides the surface both anti-reflective and self-cleaning properties. The coating is characterized by low refraction, a contact angle of at least 150° and a sliding angle of at most 10°, and includes two components: (i) an anti-reflecting coating (ARC) component and (ii) a self-cleaning coating (SCC) component. Also provided is a method for providing a substrate having a surface that is at least partially laminated with an anti-reflecting (AR) self-cleaning (SC) coating, the method including providing a substrate with at least one surface and applying a coating onto at least a part of the at least one surface, the coating including an ARC component and a SCC component.
