“…This development shows the trend that functional materials demand more and more interface research, because possibilities for applications increase. Representative examples of present research on inorganic interfaces are thermal-barrier coatings (TBC) [27][28][29][30], hard TiN-coating [31][32][33][34][35], superconductors [36], and as functional components in microelectronics [37][38][39][40][41][42], transparent conducting oxides (TCO) [43][44][45][46], photovoltaic materials [47], thermo-electrics [48][49][50][51][52], ferroelectrics [53], magnetic materials or spintronics [54,55].…”

Metal-metal-, ceramic-metal-composites (MMC, CMC) and related functional materials are steadily gaining interest for practical applications. This invited overview paper is divided into three parts. First, the importance of interfaces in material science is emphasized, then basics of computer modeling of interfaces on atomic scale is outlined, followed by the description of some interface examples and their applications. Atomistic modeling requires the specific determination of the orientation relationship between both crystal lattices facing the heterogeneous interface, the interface plane, and translation vectors of two facing crystals. Examples of the atomistic structure are described in this paper for interfaces, such as MgO/Ag, MgO/TiN, Al 2 O 3 /Fe, and others. The trend in this research is gradually, but steadily shifting from structural towards functional materials, because atomic binding at interfaces offers a broad spectrum of new properties to be utilized for applications.

“…1), thermalization losses, and below bandgap (Eg) losses of incoming light. 15,16,12 Also, we do not include the radiative recombination in the junction, which determines the theoretical saturation current of the device (refer to Section 5.3 Optimized Energy Conversion). Figure 5 shows illustrations of these different losses.…”

“…In 2009, a single junction GaAsP/InGaAs quantum well solar cell attained a peak efficiency of 28.3% under solar concentration (Ekins-Daukes et al 2013). Major benefit of incorporating a quantum well stack into a multi-junction solar cell is to increase the photocurrent up to 40 % with InGaP/ MQW/Ge.…”

Abstract:Sun is the continuous source of renewable energy, from where we can get abundant of solar energy. Concept of conversion of solar energy into heat was used back in 200 B.C. since then, the solar cells have been developed which can convert solar energy into the electrical energy and these systems have been produced commercially. The technologies to enhance the power conversion efficiency (PCE) have been continuously improved. Different technologies used for developing solar cells can be categorized either on the basis of material used or techniques of technology development which is further termed as 'first generation' (e.g. crystalline silicon), 'second generation' (thin films of Amorphous silicon, Copper indium gallium selenide, Cadmium telluride), 'Third generation' (Concentrated, Organic and Dye sensitize solar cell). These technologies give PCE up to 25% depending on the technology and the materials used. Nanotechnology enables the use of nanomaterial whose size is below 100 nm with extraordinary properties which has the capability to enhance the PCE to greater extent. Various nanomaterials like quantum dots, quantum well, carbon nanotubes, nanowire and graphene have been used to make efficient and economical solar cells, which not only provide high conversion efficiency economically but also are easy to produce. Today, by using nanotechnology, conversion efficiency up to 44.7 % has been achieved by Fraunhofer Institute at Germany. In this review article, we have reviewed the literature including various patents and publications, summarized the history of solar cell development, development of different technologies and rationale of their development highlighting the advantages and challenges involved in their development for commercial purpose. We have also included the recent developments in solar cell research where different nanomaterials have been designed and used successfully to prove their superiority over conventional systems.
