We report on the results of the investigation of optical properties and structure of PECVD deposited thin films of hydrogenated polysilicon determined by UV–Vis and IR spectroscopy. The influence of the hydrogen dilution of silane plasma at the PEVCD deposition on the film properties was investigated. The refractive index, the optical band gap energy and the microstructure of hydrogen and oxyge...

In this article, the effect of plasmonics properties of metal nanorods and nanoparticles on solar cell performance were investigated and simulated. Due to the classic solar cell disadvantages, it seems that a plasmonic solar cell is one of these methods. In plasmonic solar cells, because of plasmonic effect, a high electric field builds around metal nanoparticles so that high conversion efficie...

The vast majority of photovoltaic (PV) solar cells produced to date have been based on silicon wafers, with this dominance likely to continue well into the future. The surge in manufacturing volume over the last decade has resulted in greatly decreased costs. Multiple companies are now well below the US$1 W⁻¹ module manufacturing cost benchmark that was once regarded as the lowest possible with...

Several materials science type research topics are described in which advantageous use of crystal symmetry considerations has been helpful in ferreting the essential elements of dislocation behavior in determining material properties or for characterizing crystal/polycrystalline structural relationships; for example: (1) the mechanical strengthening produced by a symmetrical bicrystal grain bou...

Countries all over the world are making their contribution to common goal of energy saving and emission reduction. Solar is gaining more attention as a renewable source. Polysilicon an important raw material for solar panels production polysilicon vital part photovoltaic industry. typical process industry enterprise, its continuous highly intensive. Therefore, it necessary forecast analyze cons...

Effects of temperature on electrical parameters of polysilicon solar cells, fabricated using the phosphorous spin-on diffusion technique, have been studied. The current density–voltagecharacteristics of polycrystalline silicon solar cells were measured in dark at different temperaturelevels. For this purpose, a diode equivalent model was used to obtain saturation current densi...

this research reports a facile ultrasonic approach for the synthesis of iron vanadate (fevo4) nanoparticles with the aid of ammonium metavanadate (nh4vo3) and fe(no3)3.9h2o as the starting reagents without adding external surfactant, capping agent or template in an aqueous solution. furthermore, to examine the solar cell application of as-synthesized iron vanadate (fevo4) nanoparticles, fto/tio...

A solar cell is an electronic device which not only harvests photovoltaic effect but also transforms light energy into electricity. In photovoltaic phenomenon, a P-N junction is created to form an empty region.  The presented paper aims at proposing a new highly efficient InGaN/Si double-junction solar cell structure. This cell is designed to be used in a real environmental situation, so only s...
