About Principle of photovoltaic panel silicon wafer refining
Thinning the silicon wafer well below the industry-standard 160 μm, in principle reduces both manufacturing cost and capex, and accelerates economically-sustainable expansion of PV manufacturing.

In this study, the thermodynamic criteria for EoL silicon wafers refining using three most typical metallurgical refining processes: oxidation refining, evaporation refining, and solvent refining were systemically and quantitatively evaluated.
PV is the fastest-growing segment of the MG-Si market (approx. 40%/yr). Approx. 2 kg of MG-Si are used to make 1 kg of refined silicon. Additional refining capacity needed to keep up with PV growth. MIT 2.626/2.627 – October 13 & 18, 2011 12.
To overcome this obstacle, we have advanced a way of recuperating silicon from waste PV panels and their efficient utilization in battery technology. A patented technique was used to deconstruct PV panels into various materials stream where the recovered silicon was purified by adopting a KOH-based green chemistry approach.
The technology for silicon recovery through sintering encompasses high-temperature smelting [13], slag refining process [14], electromagnetic induction refining [15], and blowing refining [16]. Major methods for physically separating and recovering silicon consist of manual sorting, electric sorting, and flotation [ 4 ].
As the photovoltaic (PV) industry continues to evolve, advancements in Principle of photovoltaic panel silicon wafer refining have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.
