Nano Bio-silicon

Nano-crystalline silicon (Nc-Si), sometimes also known as microcrystalline silicon (μc-Si), is a form of porous silicon. It is an allotropic form of silicon with a paracrystalline structure that is similar to amorphous silicon (a-Si), in that it has an amorphous phase. A fine yellow-brown powder composed of spherical particles of silicon, the optic and electric properties of silicon nanoparticles has made them a favourite among nanoparticle researchers in recent years, revealing a multitude of new applications and improvements on existing ones. Silicon nanoparticles come in a variety of sizes, mostly falling into smaller 5-25nm configurations or larger 80-100 nm configurations.

Silicon (Si) Nano powder Applications

• Lithium-ion Battery - One of the most exciting applications of silicon nanoparticles revealed by research a few years ago lithium-ion batteries with extreme performance, as high as triple the energy storage potential of regular lithium-ion batteries. Research continues to seek ways to make the most of silicon nanostructures in energy storage.

• Solar Energy Cell - Due to its unique optical and conductive properties, silicon nano-powder serves as a key material in the production of various solar energy cells, including thin-film solar cells and amorphous silicon solar cells. Continued research shows multiple avenues to improve the efficiency, efficacy, and cost of producing solar cells with these materials and other nano-materials exhibiting similar optical properties.

• Semiconductors - Due to additional quantum effects such as quantum confinement seen at the nanostructure size, silicon nanoparticles have seen intense research as a semiconductive material. Precision electronics manufacturing and production of unique alloys and slurries have made thorough use of silicon nanopowders already.

• Optical properties - As with many nanoparticles, silicon produces unexpected optical properties as a nanostructure, due to the confinement of electrons and quantum effects. This makes them of particular interest in fields ranging from simple aesthetic design work to solar energy research. As with many other nano-powders, silicon nano-powders have also been thoroughly researched for applications in biomedicine and bio-sensing.
