“…UV-light cut and low emissivity self-cleaning glazing can be achieved by integrating CeO 2 and TiN with TiO 2 via sol gel processing [50]. The benefits of integrating antireflective properties with self-cleaning coatings using typically sol-gel processing and sputtering processes have been reported [51][52][53]. It is well known that in photovoltaic cells glass transparency is strictly linked with efficiency which is believed to drop by 33% per 1 g/m 2 of dust accumulation on the surface [54].…”

Functional thin films provide many opportunities for advanced glazing systems. This can be achieved by adding additional functionalities such as self-cleaning or power generation, or alternately by providing energy demand reduction through the management or modulation of solar heat gain or blackbody radiation using spectrally selective films or chromogenic materials. Self-cleaning materials have been generating increasing interest for the past two decades. They may be based on hydrophobic or hydrophilic systems and are often inspired by nature, for example hydrophobic systems based on mimicking the lotus leaf. These materials help to maintain the aesthetic properties of the building, help to maintain a comfortable working environment and in the case of photocatalytic materials, may provide external pollutant remediation. Power generation through window coatings is a relatively new idea and is based around the use of semi-transparent solar cells as windows. In this fashion, energy can be generated whilst also absorbing some solar heat. There is also the possibility, in the case of dye sensitized solar cells, to tune the coloration of the window that provides unheralded external aesthetic possibilities. Materials and coatings for energy demand reduction is highly desirable in an increasingly energy intensive world. We discuss new developments with low emissivity coatings as the need to replace scarce indium becomes more apparent. We go on to discuss thermochromic systems based on vanadium dioxide films. Such systems are dynamic in nature and present a more sophisticated and potentially more beneficial approach to reducing energy demand than static systems such as low emissivity and solar control coatings. The ability to be able to tune some of the material parameters in order to optimize the film performance for a given climate provides exciting opportunities for future technologies. In this article, we review recent progress and challenges in these areas and provide a perspective for future trends and developments.

“…For PV the AR glass etching, despite its high durability, could not compete with the large-scale developments of sol-gel coatings and physical vapour deposition (PVD) technologies adapted to PV within the last two decades. Detailed overviews of several AR technologies are provided, for example, by Cathro et al [39], Raut et al [40], and Askar et al [41].…”

This chapter provides an overview of the physical challenges and concepts for light management in solar modules, as well as established solutions and current and novel approaches to realize the ambitious goal of the International Technology Roadmap for Photovoltaic (ITRPV) roadmap. Focusing on the typical construction of the crystalline silicon solar modules, a description of the physical phenomena that determine the losses of a light beam on its path through the several layers of a module is provided. The physics of anti-reflection and light trapping/light redirection concepts is provided with the report on experimental and simulation techniques to assess the achievable progress under consideration of the real field situation, expressed in parameters like spectral distribution and varying incidence angle of sunlight, or diffuse lighting. The chapter discusses technological solutions that are already implemented, that are on the threshold to industrial use, and novel concepts currently under basic investigation

“…Nagpal et al proved that smooth-templated structures with optimum surface-plasmon-propagation length are critical for plasmonic composite chip devices and can be fabricated by patterning methods, since the anisotropic engraved silicon pyramidal pits are very smooth and homogeneous (well-oriented) Nomura, 2012;Liu et al, 2015). Also, reverse silicon pyramids can be utilized to pattern polymer pyramids instead of templating pure Au nanopyramid arrays (Lyshevski, 2005;Askar et al, 2013;Liu XF et al, 2013;Liu X et al, 2015). Metal films can coat polymer structures to fabricate functional plasmonic nanoarrays.…”

Nanomaterials-based diagnostics have tremendous advantages over other conventional diagnostic systems in terms of sensitivity, specificity, and portability owing to the unique intrinsic properties of nanomaterials. Thus, there is a substantial need to develop and employ a broad spectrum of nanomaterials for biological and diagnostic applications. In this review, we focus on nanomaterials-assisted disease diagnosis utilizing different techniques such as photoluminescence, colorimetry, fluorescence, electrochemistry, microarray methods, surface plasmon resonance, and surface-enhanced Raman spectroscopy. In these techniques, different nanomaterials, including but not limited to gold and silver materials, metal oxides, and semiconductors, were employed according to their all-purpose chemical and physical properties. As the new properties of nanomaterials are discovered, their contributions to nanobiotechnology applications are vastly increased. In this review, the features of the selected nanobiomaterials, biological tag-modified nanomaterials, and their outstanding applications for the detection of specific biotargets have been summarized according to the latest studies. Nanomaterials contribute to the fields of photo/chemotherapy and biomedical imaging in particular, since all the biological events happen within this size range and beneficiary roles of nanoparticles (NPs) are countless in biomedical applications due to their unique physical and chemical properties. However, due to the necessity of specificity and selectivity, there is a clear ambition to study bioconjugation of NPs to increase the efficiency of the targeted biological applications. Thus, the combination of the specificity and the intrinsic properties of biohybrid NPs facilitate diagnostic and therapeutic applications.
