Waste is displaced resource!
Innovative technology from RoSi recovers photovoltaic (PV) Silicon, the no.1 cost driver in PV module production, from diamond wire wafering kerf. The proprietary and integratability process and equipment lead to significant reduction in :
A smart combination of micro-powder technology, Silicon surface conditioning and dedicated purification process.
Low-cost process as a result of no high temperature and high pressure steps are involved before Silicon powder melting step.
A laboratory prototype has been realized to feed recovered Silicon powder from wafering kerf. An industrial prototype which treats the wafering kerf, conditions the recovered Silicon powder, and purifies the melted Silicon, will be realized at the end of the project in Q4/2017.
Recovery of Silicon from PV wafering process.
Recovery of Silicon powder from poly-Silicon production process in FBR (Fluidized Bed Reactor).
