Production of Silicon Nanoparticles for Use in Solar Cells

Thermal Disproportionation for the Synthesis of Silicon Nanocrystals and Their Photoluminescent Properties

“…Besides, carrier multiplication was observed in silicon, which would dramatically enhance the photovoltaic efficiencies for solar cells (Timmerman et al, 2011). Sukhanov's group indicated that the 12% increase of power conversion efficiency of silicon quantum dot solar cell came from the defect passivation at the surface of solar cell by SiNCs and the decrease of the optical reflectance (Dorofeev et al, 2014;Gribov et al, 2018). Engineering the bandgap of SiNCs can further improve the solar cell efficiency.…”

Advances in Laser Ablation Synthesized Silicon-Based Nanomaterials for the Prevention of Bacterial Infection

“…Silicon, with a chemistry similar to that of carbon and of great abundance in the earth, is another of the materials whose miniaturization has led to the appearance of new properties with application in numerous fields such as medicine, structural materials, agricultural field to the environmental bioremediation, solar cells, etc. [ 2 , 3 , 4 ]. Depending on the conditions and techniques used during the synthesis, it is possible to obtain two different types of silicon-based nanomaterials: (i) nanomaterials whose composition is identical to that of the original silicon (Si–Si), which from now on will be call silicon-nanomaterials (Si-NMs) or (ii) silicon oxide (silica, SiO 2 ) nanomaterials that will be denoted as silica-nanomaterials (Silica-NMs).…”

Microwave plasma-assisted silicon nanoparticles: cytotoxic, molecular, and numerical responses against cancer cells

“…4 For various applications, it's necessary to obtain well characterized nanocrystals of SiNPs as varying the size of nanomaterials can change their fundamental properties and generate various properties such as electronic, optical, magnetic, and catalytic properties, associated with their nanoscale or quantum-scale dimensions. 5 There is a wide range of applications for silicon and its nanoparticles, many of which are well-established, such as bioimaging, 6,7 inorganic/organic light emitters, 8,9 solar cells, 10,11 dye-sensitized solar cells, 12 lithium-ion batteries, 13,14 corrosion shields, 15 anti-static lms and coatings, 16 energy storage 17 and catalysts. 18 To get nanostructures in the form of nanoparticles, various physicochemical methods have been adopted, such as the chemical solution method, 19 sol-gel method, 20 hydrothermal method, 21 ball milling method, 22 one-pot synthesis, 23 electrochemical etching, 24 hydrogen-terminated solution process, 25 reverse micelle process 26 and the micro-emulsion technique.…”
