design and optimization of a single crystalline silicon (c-si) solar cell is performed to achieve the maximum light conversion efficiency. various parameters such as doping concentration and thicknesses, and geometrical dimension of surface pyramids are studied. the inverted surface pyramid is used to increase the efficiency of the solar cell, and engineered oxide layer is used as the passivati...

In this paper, we demonstrate a novel salinity sensor based on Tamm-plasmon-polariton (TPP), comprising different shapes of Bragg reflector (ordinary, texturing, and sawtooth) metallic layer. The finite element method is used to study the considered structure sensing performance by using COMSOL multiphysics simulation procedure. Here, effect surface morphology sensitivity; firstly, in case one-...

Web Graphics has become an important and new platform today, since there are more and more people that would like to have 3D graphics supports on the Web. In order to distribute 3D graphics applications from servers to clients on different platforms, a general-purpose 3D graphics library for Java called jGL is developed as the base of the 3D graphics applications for Web Graphics. To make jGL t...

The new material developments in the field of thermoelectrics over past two decades have resulted materials with unique transport properties as well synthetic approaches. Enhanced thermoelectric these through thermal conductivity reduction and electrical enhancement strategies such nano-structuring band engineering also been reported. Nevertheless, system upon which all are compared continues t...

Starting Bi2Te3 and Ni powders were spark-plasma-sintered (SPS) to prepare thermoelectric cermet composites consisting of matrix with different content, x, ferromagnetic filler (x = 0.00, 0.50, 0.85, 1.25 1.50 at. %). Grained is texturing under sintering. Texturing degree x-dependent that attributed ability particles act as lubricant. New trigonal NiTe2 phase formed SPS-process. The phases corr...

Inverted pyramid-texturing of silicon surface has been proven to have great application potential in solar cells. In this paper, we utilized Ag-assisted chemical etching (Ag–ACE) technology combing with polyvinylpyrrolidone (PVP) fabricate an inverted pyramid textured Si surface. We call it Ag@PVP–ACE. The effect different experimental parameters on results was observed. show that the microstru...
