Rosi valorizes the high quality silicon contained in photovoltaic (PV) industrial waste through recycling.
To make photovoltaics a greener source of energy, Rosi brings back silicon considered as waste into the PV production value chain. Recycling silicon through Rosi reduces at least 30% of CO2 emissions, increases production efficiency and reduces the cost of PV modules. Overall, this renders the PV industry into a circular economy. The recycling process includes a purification of silicon kerf, the sludge waste left after cutting a slice of PV silicon from an ingot. This results in high quality silicon (over 99.9%) through an environmentally friendly process. There is also a controlled conditioning of the resulting powder into the appropriate form for the targeted application.
- •Efficiency booster for PV industry.
- •Reduction of PV module cost
- •No acid or base used for the purification.
- •Recycled silicon around 50% cheaper without compromising the quality of the raw material.
