…substrate; coating the nano-wires with a first silicon layer; then coating the nano-wires with a second, differently shaped silicon layer). Manufacturing costs of Amprius’ silicon anode batteries can be guessed,…
…at a rate of 100-300μm per hour. This is 1,000x longer than forming mono-crystalline poly-silicon from liquid silicon via the Czochralski method at 1,425ºC and at 25-100mm/hour. Thus a very…
…silicon metal, purified into polysilicon, upgraded into mono-crystalline poly-silicon and ultimately used in solar cells. We estimate silicon explains $0.1/W of the cost of a $0.3/W panel. There is no…
Silicon carbide power electronics will jolt the energy transition forwards, displacing silicon, and improving the efficiency of most new energies by 1-10 pp. Hence we wonder if this disruptor will…
Nexwafe technology review. Nexwafe is developing a next-generation PV silicon technology called the EpiWafer process, growing standalone silicon wafers onto mono-crystalline seed wafers, with no need to slice ingots and…
Sila Nanotechnologies was founded in Silicon Valley in 2011, to develop smaller and denser batteries, using silicon-comprising nano-particles in the battery anodes. Thus it claims to have made “the biggest…

Polysilicon is a highly pure, crystalline silicon material, used predominantly for photovoltaic solar, and also for ‘chips’ in the electronics industry. Global polysilicon capacity is estimated to reach 1.65MTpa in…
…of a substance forms from its constituent elements in their reference state. For example, the chemical element silicon will slowly oxidize when exposed to air, yielding pure white sand (Si…
