“…Unfortunately, a dark color limits the architectural integration. A study shows that more than 85% of architects prefer solar collectors in building having other colors than black, even if they loose some efficiency [4]. Different ideas have been suggested, such as spectrally selective colored paint (TISS paint) [5], and colored collector glazing [6].…”

“…Even though this work is a continuation of efforts reported in a broader metal-dielectric materials research area [26][27][28], and alternative material system solutions might exist in industrial settings, we are unaware, to the best of our knowledge, of any prior reports on achieving environmentally stable THR coatings based on using the same material combination while targeting the accurate control over the chromaticity.Metal-dielectric thin-film coatings (spectral filters featuring controlled apparent colors) have numerous application possibilities in the fields of building architecture, windows, printed products, and other decorative coatings. There are several reports that have been published in the literature about the color properties of different types of thin-film materials (most of these are single-layer), except a couple of them were found to deal with the color properties of multilayer thin-film structures [29][30][31][32][33][34][35][36][37][38][39]. For example, Dalapati et al, reported about the preparation and properties of color-tunable low-cost transparent heat reflectors using copper and titanium oxide for energy-saving applications [40].…”

Coated glass products, and especially the low-emissivity coatings, have become a common building material used in modern architectural projects. More recently, these material systems became common in specialized glazing systems featuring solar energy harvesting. Apart from achieving the stability of optical parameters in multilayer coatings, it is also important to have improved control over the design of visual color properties of the coated glass. We prepare metal-dielectric composite (MDC)-based multilayer thin-film structures using the radio frequency (RF)-magnetron sputtering deposition and report on their optical and chromaticity properties in comparison with these obtained using pure metal-based Dielectric/Metal/Dielectric (DMD) trilayer structures of similar compositions. Experimentally achieved Hunter L, a, b values of MDC-based multilayer building blocks of coatings provide a new outlook on the engineering of future-generation optical coatings with better color consistency and developing approaches to broaden the range of achievable color coordinates and better environmental stability.Low-E coatings can still be expected to represent core technology in advanced windows, whether or not additional technologies are embedded. The Low-E coatings are typically structured as metal-dielectric multilayer thin films, which are designed to prevent heat leakage (from the inside of buildings into the environment) by providing strong and very wide-band reflection of thermal infrared wavelengths.In recent years, the optical properties of metal-dielectric coatings and their influence on building energy efficiency have been studied extensively due to their superior performance compared to other multilayer coating structure types. The metal-dielectric coatings performance mainly depends on the choice of materials and its design philosophy [7][8][9][10][11][12][13][14][15]. Most (or practically all) products available today from this category (featuring high spectral selectivity) employ at least two silver (Ag) layers within their structure, and these coatings cannot withstand prolonged (weeks-scale) exposure to either the ambient atmospheric air or dry-heat test temperatures in excess of 160-180 • C. However, the stability problems of ultrathin Ag layers (normally of less than 20 nm thickness) originate from a range of factors related to the metal layer growth morphology. To overcome these issues, a significant number of research works have been proposed, conducted, and resulted in reporting various solutions, where some of them require more complex materials processing and process parameters optimization [10][11][12][13][14][15][16][17][18][19]. Several reports have been published about the properties of various metal-dielectric composite (MDC) thin-film layer chemistries, including Ag + SiO 2 , Ag + TiO 2 , and Ag + MgF 2 ; however, most of them were about metal-dielectric nanoparticle array properties of interest for various applications [20][21][22][23]. We previously proposed and partially implemented the developmen...

“…Thin films with these characteristics were initially proposed by Schüler et al (2004) for solar thermal applications, then succeeded by simulation and experimental studies using different film deposition methods including reactive magnetron sputtering (Boudaden et al, , 2005Mertin et al, 2013), sol-gel dip coating (Schüler et al, 2006) and spray pyrolysis deposition (Dudita et al, 2014). The sol-gel dip coating technique is most suited to large scale applications, such as solar collector glazing (Schüler et al, 2006).…”
