“…Nanocermets are likely to be potential candidates for solar energy conversion because they exhibit strong absorption in the visible region, which occurs because of surface plasmon resonance phenomenon, also known as quantum confinement effect [65]. The optical properties of nanocermet strongly dependent on the particle shape, size, and concentration of the particle in the matrix, particle distribution and local dielectric environment of the dielectric matrix [66]. Stable nanocrystalline are the most desirable for diffusion barrier application and also need to develop nanostructured materials for solar energy conversion as special physical effects related to the nanometer scale do rise to interesting microscopic properties [67].…”

Solar energy has maximum potential in comparison with other renewable energy sources. Solar thermal conversion is one of the direct methods for harnessing solar energy using solar selective absorbers. This review article summarizes the recent research progress on the high-temperature solar selective coatings, methodology, and process involved in coating, computer modeling, as well as designs of coatings, optical, compositional, and structural properties of selective coatings. The major bottleneck in developing a solar selective coating is its stability in air at temperature higher than 450°C that possess thermal and structural stability in both individual and combined layers. New possibilities to overcome the abovementioned problems on the performance of solar selective coatings are discussed.

“…Nanocomposite thin films or coatings for solar energy conversion should have a high absorption of solar radiation and low thermal emission at their operating temperatures. There are many different thin films solar cells system, such as: a-Si:H/a-SiGe:H/nc-Si:H, a-Si:H/nc-Si:H/nc-Si:H, a-Si:H/nc-Si:H. Other promising thin films solar cells may include CuInS 2 , CuInGaSe, CdTe, TiO 2 , CdS (Yin, 2007). Hydrogenated amorphous silicon (a-Si:H) or nanocrystalline silicon (nc-Si) is currently used in thin film transistor liquid displays (TFT-LCDs).…”

Induction Composite materialsA composite is a multiphase solid material. It is incorporated by two or more individual materials through physical or chemical methods. The performance of different materials to complement each other will produce synergistic effects (Ivanov et al., 2008;Lu et al., 2010). The overall property of composite materials is better than that of each original material to meet different requirements. These properties include mechanical, electrical, thermal, optical, electrochemical, catalytic behaviors etc. For example (Lu et al., 2010), investigating the synergistic effect of carbon nano-fiber (CNF) and carbon nano-paper on the shape recovery of shape memory polymer (SMP) composite shows that the combination of CNF and carbon nano-paper can improve the thermal and electrical conductivities of the SMP composite, which are much better than each of the components. The individual materials in a composite are referred to as two constituent materials. The two constituent materials are matrix and reinforcement. The matrix material is a frame to support the reinforcement material. So the reinforcement material can keep its relative position. The reinforcement is a functional material which can enhance the matrix properties. Composite metal matrix (substrates) includes aluminum, copper, titanium, magnesium and its alloys and nonmetallic matrix includes synthesized resin, rubber, ceramics, graphite and carbon and so on. Reinforcement mainly includes glass fiber, carbon fiber, boron fiber , aramid fiber, silicon carbide fiber , asbestos fiber, whisker, metal wire and fine grain etc. In order to make use of synergistic effect to improve composite properties, optimum combination of matrix and reinforcement should be chosen. Nanocomposites and their propertiesA nanocomposite is a special composite where one of the phases has one, two or three dimensions less than 100 nanometers (nm, 10 -9 m). A nanocomposite also includes the material where the structures between the different phases that make up the material are in nano-scale (Beecroft & Ober, 1997). In the broadest sense, nanocomposites can also include porous media, colloids, gels and polymers, because in these materials the particles or structures are in nano scale. One nanometer is equivalent to the length to tightly line up www.intechopen.com Advances in Composite Materials for Medicine and Nanotechnology 212 10~100 atoms. Nano-materials include nano-powders, nano-fibers, nano-particles and nanothin films. Their structures are between atom (molecular) size and macro size. Materials in nano-scale have special effects such as quantum size effect, surface effect, small-size effect and macroscopic quantum tunneling effect etc. Quantum size effectQuantum size effect is one of the fundamental physical properties of nano-particles. When the particle size decreases to a nano-scale, the electronic energy levels of the particle atom become discrete and the energy gap becomes wider. This phenomenon is called quantum size effect. This effect does not come into ...
