1. Solar energy – an important player in the Energy Transition
With the foreseeable end of the fossil-fuel era on the horizon, human society is looking for reliable alternatives to provide energy. The use of green energy sources becomes essential for the sustainable development of our planet. Photovoltaics (PV), a technology in which light is converted directly into electricity, is one of the most promising candidates. PV is an appealing technology because it is a renewable, environmentally benign, and domestically secure energy source. Moreover, PV technology is modular and can be readily scaled to meet different demands. PV systems range in size from several kW residential systems to utility-scale multi-100MW, even GW installations. In 2017, more than 100GW PV modules have been installed worldwide, a more than 20% increase compared to 2016.
ROSI owns two proprietary core technologies:
- ROSI Tech 1 – Green Wash: purification of Si micro-powder from kerf with no toxic chemicals
- ROSI Tech 2 – CCS (Controlled Conditioning of Silicon): melting of Silicon powder into Silicon melt, with granule sizes ranging from hundreds of nano-meters to tens of micron-meters with additional purification on Carbon and Oxygen content.
For Silicon kerf recycling, a combination of Green Wash and CCS will allow feeding of DSS furnace by the so-obtained Silicon granules or Silicon melt.
For Silicon fines recycling, CCS alone will offer granules or melt for different purposes.
