“…The front cover glass required for photovoltaic (PV) module insulation is the first surface to receive irradiation toward the solar cell, and the first surface to limit the photon flux impinging due to optical losses, which can be counteracted by means of antireflective (AR) coatings. The soiling adherence inherently disrupts the intended function of the AR coatings, thus reducing the power output of the PV plants. − This issue is hence motivating the increased research attention toward AR and antisoiling coatings for photovoltaic solar panels, lasers, automobiles, optical instruments, and solar collectors. − …”

We report on the optical and morphological properties of silica thin layers deposited by reactive RF magnetron sputtering of a SiO 2 target under different oxygen to total flow ratios [r(O 2 ) = O 2 /Ar, ranging from 0 to 25%]. The refractive index (n), extinction coefficient, total transmission, and total reflectance were systematically investigated, while field-emission scanning electron microscopy, atomic force microscopy, and threedimensional (3D) average roughness data construction measurements were carried out to probe the surface morphology. Contact angle measurements were performed to assess the hydrophilicity of our coatings as a function of the oxygen content. We performed a thorough numerical analysis using 1D-solar cell capacitance simulator (SCAPS-1D) based on the measured experimental optical properties to simulate the photovoltaic (PV) device performance, where a clear improvement in the photoconversion efficiency from 25 to 26.5% was clearly observed with respect to r(O 2 ). Finally, a computational analysis using OptiLayer confirmed a minimum total reflectance of less than 0.4% by coupling a silica layer with n = 1.415 with another high-refractive-index (i.e., >2) oxide layer. These promising results pave the way for optimization of silica thin films as efficient antireflection and self-cleaning coatings to display better PV performance in a variety of locations including a desert environment.

“…For large gap ceramic materials, the discrepancy in Ć values for a given metal/ large gap ceramics could be explained by the fact that for (E g > 3 eV), here will be a smaller density of inside in the ceramic crystal (practically no free charges inside) and consequently the electron transfer at metal/ceramic interfaces cannot be important [2]. As a result, the characteristic constant Ć values are negligible compared to W VDW energy and/or especially to W chem-equil energy.…”

“…Metalized ceramics by liquid metal have a crucial uses in several modern technological applications such as solar cell [1][2][3][4] electrical devices [5][6][7] and Micro Electro Mechanical Systems (MEMS) [8][9][10]. Recently, these systems are used as the conductive wiring of microelectronic circuits; there has been considerable interest in the characterization of the structure and properties of liquid metal/ ceramic interface [11].…”

“…Hence, the strength or wea1kness of bonds is the key factor to determine the interface stability: good adhesion, welded adhesion, perfect bonding, weak bonding smooth interface, etc. The metal/ceramic contact is characterized by the adhesion energy, W ad , which is the work per unit area of the interface needed to separate reversibly a metal/ceramic interface [2]. This physicochemical parameter is given by Young-Dupré equation relating surface tension of molten metal above melting temperature, γ LV , and measured equilibrium contact angle θ formed between deposited liquid metal and its ceramic substrate [12]:…”

In this chapter, we study an interfacial phenomenon between liquid metals and ceramic substrates. Therefore, investigation of these phenomena is of great importance not only in technological applications but also in fundamental understanding of physical behavior of the adhesion between two different materials as far as their electrical structures and physiochemical properties are concerned. Moreover, adhesion energy is interpreted thermodynamically by the interfacial interactions and the nature of bonding between liquid metal and ceramic material. The adhesion energy in metal/ceramic systems is determined by using an electro-acoustical model based on the propagation of the acoustic wave in the interface and strongly depends on the electric properties of combination.

В рамках работы на кремниевых солнечных элементах были получены полимерные функциональные покрытия с наночастицами серебра. Размер наночастиц, использовавшихся для создания покрытий составил ~ 100 нм. Впервые была исследована микроструктура полученных покрытий методом сканирующей электронной микроскопии. Было показано, что наночастицы имеют достаточно высокую и равномерную плотность распределения в покрытии. В покрытиях, полученных с помощью метода осушения присутствуют единичные дефекты в виде отсутствия пленки. Данные дефекты предположительно обусловлены перепадами микрорельефа на поверхности солнечных элементов и могут быть устранены путем повторного нанесения пленки. Проведенные экспериментальные исследования квантового выхода фотопреобразователей показали, что функциональные покрытия на основе полимеров с наночастицами серебра позволяют существенно улучшить характеристики кремниевых солнечных элементов. Within the framework of this study, functional polymer coatings with silver nanoparticles were obtained on the surface of silicon solar cells. The size of the nanoparticles used to create the coatings was ~ 100 nm. For the first time, the microstructure of the obtained coatings was investigated by scanning electron microscopy. It was shown that nanoparticles have a sufficiently high and uniform distribution density in the coating. In the coatings obtained using the drying method, that there are single defects in the form of the absence of a film. These defects are presumably due to differences in microrelief on the surface of solar cells and can be eliminated by reapplying the film. Experimental studies of the quantum yield of photoconverters have shown that functional coatings based on polymers with silver nanoparticles can significantly improve the characteristics of silicon solar cells.
