Electrodeposition of crystalline and photoactive silicon directly from silicon dioxide nanoparticles in molten CaCl2.
Silicon is a widely used semiconductor for electronic and photovoltaic devices because of its earth-abundance, chemical stability, and the tunable electrical properties by doping. Therefore, the production of pure silicon films by simple and inexpensive methods has been the subject of many investigations. The desire for lower-cost silicon-based solar photovoltaic devices has encouraged the ques...
متن کاملLiquid-Tin-Assisted Molten Salt Electrodeposition of Photoresponsive n-Type Silicon Films
Production of silicon film directly by electrodeposition from molten salt would have utility in the manufacturing of photovoltaic and optoelectronic devices owing to the simplicity of the process and the attendant low capital and operating costs. Here, dense and uniform polycrystalline silicon films (thickness up to 60 μm) are electrodeposited on graphite sheet substrates at 650 °C from molten ...
متن کاملThermal Diffusivities and Conductivities of Molten Germanium and Silicon
Thermal diffusivity values of molten germanium and silicon were measured by a laser flash method. Simple but useful sample cell systems were developed to keep the molten germanium and silicon shape uniform for a given thickness. In the present experimental condition, it is necessary to consider the effect of not only the radiative heat loss but also the conductive heat loss at the interface bet...
متن کاملElectrodeposition of germanium from supercritical fluids.
Several Ge(II) and Ge(IV) compounds were investigated as possible reagents for the electrodeposition of Ge from liquid CH(3)CN and CH(2)F(2) and supercritical CO(2) containing as a co-solvent CH(3)CN (scCO(2)) and supercritical CH(2)F(2) (scCH(2)F(2)). For Ge(II) reagents the most promising results were obtained using [NBu(n)(4)][GeCl(3)]. However the reproducibility was poor and the reduction ...
متن کاملElectrodeposition of Zinc From Low Temperature Molten Salt Electrolyte: Part I-Imidazole And Zinc-Chloride Electrolyte
Our R & D work was focused on the electro deposition of Zinc from imidazole as low temperature molten salt (LTMS) electrolyte with zinc chloride as a supporting salt at <100o C., without required controls from the previous existing non aqueous baths as well additive free system for the zinc deposition. Surface morphological studies and crystallographic orientation results were evaluated.
