Process of parallel wire cut with abrasive slurry of diamond or SiC grit [1]
Costs
- $15/kg for polysilicon [2]
- 3.6 cent per watt silicon costs
- 2018 had 37 cent minimum sustainable selling price, and long term prediction is 24 cents (another 30 percent reduction.
This puts PV at under $100 for a 380W panel, or about $2/lb.
Silicon Production
It is only 10 percent of panel cost,
It is currently made with electrolysis of carbon + sand. [3]
