“…For example, carbon black is added to improve electrical conductivity, titanium dioxide improves dielectric constant, and barium sulfate improves radiopacity. Because of these advantages, polysiloxanes are widely used in an immense number of industrial applications [28] varying from simple baking and measuring cups [29] to surface modifiers (elastomers/sealants, antifoaming agents, personal care products, surfactants, coatings, insulations) [30], biomedical [31], microporous organic and inorganic materials [32], and aerospace and other high-tech industries [33].…”
Rubber materials are used across a huge range of domestic and industrial applications. There are ten common types of rubber, including natural rubber, styrene-butadiene rubber, butyl, nitrile, silicone, polyurethane, hydrogenated nitrile, and so on. This book discusses several different types of rubber materials and their mechanical, optical, acoustic, and kinetic properties. This book includes six chapters. Chapter 1 by Buddhima Rupasinghe discusses the recycling of silicone-based materials. Chapter 2 by Azemi Samsuri discusses recycled carbon black based on styrene-butadiene rubber, natural rubber, and nitrile rubber compounds. Chapter 3 by Hammat Valiev et al. describes the influence of composition and structure on the properties of elastomeric composites with silicon dioxide fillers. Chapter 4 by Ntalane Sello Seroka et al. discusses sugar cane bagasse ash, an agricultural residue with potential rubber filler applications. Chapter 5 by Józef Haponiuk et al. examines the origin, specifications, and applications of natural rubber latex. Finally, Chapter 6 by Mounir Kassmi presents the characterization of hydrogenated amorphous silicon using infrared spectroscopy and ellipsometry measurements.We would like to thank all the authors for their excellent contributions. We would also like to thank the staff at IntechOpen, especially Author Service Manager Maja Bozicevic for her effective editing and support during the production of this book.

“…Subsequently, in-situ boron doped silicon films were deposited in a single cosputtering process, using an undoped silicon target (with a purity of 99.999%) and a boron target (with a purity of 99.999%) at the same time. [15][16][17] The co-sputtering process was performed at room temperature with a pressure range of 1.5 mT to 6 mT. The RF power density applied for sputtering the undoped silicon was $3.1 W/cm 2 , while the RF power density was varied with a range of from 1.9 W/cm 2 to 3.1 W/cm 2 for the boron target to obtain different dopant concentrations.…”
Of all the materials available to create carrier-selective passivating contacts for silicon solar cells, those based on thin films of doped silicon have permitted to achieve the highest levels of performance. The commonly used chemical vapour deposition methods use pyrophoric or toxic gases like silane, phosphine and diborane. In this letter, we propose a safer and simpler approach based on physical vapour deposition (PVD) of both the silicon and the dopant. An in-situ doped polycrystalline silicon film is formed, upon annealing, onto an ultrathin SiO x interlayer, thus providing selective conduction and surface passivation simultaneously. These properties are demonstrated here for the case of hole-selective passivating contacts, which present recombination current densities lower than 20 fA/cm 2 and contact resistivities below 50 mX cm 2. To further demonstrate the PVD approach, these contacts have been implemented in complete p-type silicon solar cells, together with a front phosphorus diffusion, achieving an open-circuit voltage of 701 mV and a conversion efficiency of 23.0%. These results show that PVD by sputtering is an attractive and reliable technology for fabricating high performance silicon solar cells.
“…The hydrogen concentration and the structural disorder are both influenced by the substrate's temperature, and both variables are required to explain an observed local minimum of gap, but the silicon monohydride (SidH) bond density only accounts for this dependency [26]. All of these outcomes support the assertion that even though research on the a-Si: H material has improved in terms of the latter's ability to be doped to increase its transport capabilities [27,28], it's still challenging to regulate the factors that affected its optical qualities. Instead, because much less material is needed to respond and totally absorb the light, ultra-thin film optoelectronic devices, particularly those built of hydrogenated amorphous silicon a-Si: H, have the potential to be less expensive.…”
We described the primary mixed compositions of hydrogenated amorphous silicon on the surface of glass (7059) in this chapter and distinguished them optically by combining the outcomes of infrared spectroscopy and ellipsometric tests. The particular hydrogen content of the aspherical voids created determines the energy level of the optical band, which ranges from 1 eV to 4 eV depending on how passivated or unpassivated the composition is. Additionally, the dielectric response is influenced by the size and proportion of the vacuum occupation relative to the surrounding phase, and each dielectric response is based on how much the implicated components have been passivated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
