由于能源的消耗，太阳能电池越来越受到人们的关注。然而，作为商业中主要应用的晶硅太阳能电池存在表面入射光反射以及无法吸近红外光的性质限制了晶硅太阳能电池效率的进一步提高。因此，我们设计了一种内嵌二维光子晶体纳米圆锥的频率上转换超薄晶体硅太阳能电池，其中铒镱共掺氟化钇钠(NaYF4:Er3+/Yb3+)上转换层夹在Ag背反射层和活性层中间，利用COMSOL Multiphysics ®中波动光学模块系统的研究了具有不同结构和电介质填充材料纳米圆锥阵列对频率上转换晶硅太阳能电池陷光增效的影响。利用周期性边界条件及有限元的思想构建了电池计算单元，在300-1150 nm ... Mehr lesen
Excilamps are artificial Ultraviolet sources based on the emission of excimers or exciplexes. The latter are excited states of weakly bound rare gas or halide/rare gas atoms which emit a photon in the UV region when they dissociate. Dielectric Barrier Discharge (DBD) excilamps are ... Mehr lesen

Micro electrical discharge machining (MEDM), a scaled down version of EDM process, is a micro machining process used to fabricate micro holes and intricate shapes in electrically conductive materials irrespective of its hardness. In this process, an electric spark is generated in the gap ... Mehr lesen
In an experimental nuclear fusion facility dust is generated both during normal machine operations and by macroscopic erosion of the plasma facing materials due to intense thermal loads. This dust can be mobilized by air ingress in case of LOVA (Loss of Vacuum Accident) threaten safety ... Mehr lesen
The glow discharges in argon at pressures of 1 to 20 mTorr are modeling using COMSOL Plasma Module. DC glow discharge with secondary electron emission is compared to low pressure arc with thermionic emission. Boundary conditions on dielectric discharge tube walls are compared to that of ...

This work uses COMSOL to simulate the Dielectric Barrier Discharge (DBD) lamp coupled to the external electrical circuit. The coupled system is modeled to capture the effect of the electrical parasitic elements on the efficiency of the DBD which is more realistic as compared to previous ... Mehr lesen
In this paper, detail magnetostructural analysis of fusion grade superconducting toroidal field coils that are used in ‘tokamaks’ is presented. The stresses that arise due to Lorentz forces in large size superconducting coils that carry high currents are of catastrophic type in nature. ... Mehr lesen
It was suggested long ago that a theoretical model of a near-cathode region in a DC glow discharge admits multiple steady-state solutions describing different modes of currrent transfer. Even the most simple self-consistent models should admit such multiple solutions. In the present ... Mehr lesen
