“…This shows that the introduction of Fe and Ni has a strong effect on the optical absorption capacity of 3C-SiC system. Introducing Co atoms into 3C-SiC can obtain an energy conversion efficiency of more than 56.6 at.%, and has a very superior light absorption coefficient [61]. The light absorption coefficient of the (Fe, Ni) co-doped 3C-SiC system in our paper has a similar trend and value.…”

The electronic structures, magnetic properties and optical properties of (Fe, Ni) co-doped 3C-SiC system are systematically studied based on the first principles calculation. The results show that Fe single doped, Ni single doped, and (Fe, Ni) co-doped system all induce magnetism. The most stable (Fe, Ni) co-doped systems is determined by calculating the magnetic coupling energies of ten different configuration. The (Fe, Ni) co-doped systems indicated that have a higher Curie temperature and the (1, 7) configuration significantly improves FM stability compared to other configurations. In addition, the results of the optical properties of (Fe, Ni) co-doped 3C-SiC exist absorption in the entire infrared, visible, and ultraviolet light regions, which has a substantial change compared with the undoped system. An effective way is comfirmed to improve the magnetic and optical performance of 3C-SiC.

High efficiency, fuel flexibility, and sustainable energy conversion make fuel cells attractive compared to conventional energy systems. The direct ethanol fuel cells have attracted much attention because of the direct utilization of ethanol fuel. Anode materials are required to enhance the catalytic activity of the liquid fuel, which oxidize the fuel at lower operating temperature. Therefore, the catalytic effect using silicon carbide has been investigated in the LiNiO2−δ anode. The material has been characterized, and it is found that SiC shows a cubic structure and LiNiO2−δ exhibits a hexagonal structure, while the LiNiO2−δ–SiC composite exhibits a mixed cubic and hexagonal phase. Scanning electron microscopy depicts that the material is porous. The Fourier transform infrared spectroscopy analysis shows the presence of Si–O–Si, Si–C, CO, and Si–OH bonding. The LiNiO2−δ–SiC composite (1:0.3) exhibited a maximum electrical conductivity of 1.34 S cm–1 at 650 °C with an electrical band gap of 0.84 eV. The fabricated cell with the LiNiO2−δ–SiC anode exhibits a power density of 0.20 W cm–2 at 650 °C with liquid ethanol fuel. The results show that there is a promising catalytic activity of SiC in the fuel cell anode.

“…Solar energy plays an essential role in a wide range of renewable energy sources, and many investments have been made in research to improve efficiency of solar cells. [1][2][3][4][5][6][7][8][9][10][11][12] However, price of electricity from solar energy is higher than the energy produced by conventional energy sources. [13][14][15] By combining low production costs and reasonable performance, thin-film photovoltaics are an attractive option to reduce the total cost per Watt of solar energy.…”

The cluster-shaped plasmonic nanostructures are used to manage the incident light inside an ultra-thin silicon solar cell. Here we simulate spherical, conical, pyramidal, and cylindrical nanoparticles in a form of a cluster at the rear side of a thin silicon cell, using the finite difference time domain (FDTD) method. By calculating the optical absorption and hence the photocurrent, it is shown that the clustering of nanoparticles significantly improves them. The photocurrent enhancement is the result of the plasmonic effects of clustering the nanoparticles. For comparison, first a cell with a single nanoparticle at the rear side is evaluated. Then four smaller nanoparticles are put around it to make a cluster. The photocurrents of 20.478 mA/cm2, 23.186 mA/cm2, 21.427 mA/cm2, and 21.243 mA/cm2 are obtained for the cells using clustering conical, spherical, pyramidal, cylindrical NPs at the backside, respectively. These values are 13.987 mA/cm2, 16.901 mA/cm2, 16.507 mA/cm2, 17.926 mA/cm2 for the cell with one conical, spherical, pyramidal, cylindrical NPs at the backside, respectively. Therefore, clustering can significantly improve the photocurrents. Finally, the distribution of the electric field and the generation rate for the proposed structures are calculated.
