Resolartech recycles end‑of‑life photovoltaic modules using its proprietary GST dismantling and SWT silicon‑cleaning processes to separate glass, metals, and high‑purity 6N‑grade silicon. The recovered silicon is cast into ingots, sliced into wafers, and used to manufacture new solar cells and fully recycled modules with efficiencies up to 20.7%, helping PV manufacturers and project developers close the material loop.

Problem
Retired and damaged photovoltaic (PV) modules generate large amounts of waste glass, metal, and silicon, and traditional recycling methods often yield low recovery rates and require extensive processing, limiting the availability of high‑purity recycled silicon for new solar cells.
Solution
Resolartech applies a proprietary GST green dismantling process combined with its self‑developed SWT silicon cleaning technology to separate PV modules into reusable glass, metals, and 6N‑grade silicon ingots. The RESOLAR separation method physically fractures and chemically treats the modules, achieving high separation efficiency of cells from glass. Recovered cell fragments undergo silver removal and thorough washing to produce high‑purity silicon, which is then cast into 6N silicon ingots, sliced into wafers, and fabricated into new solar cells. The company also supports tiered reuse of whole modules, enabling a closed‑loop lifecycle for PV equipment and reducing landfill waste.
Target Audience
Primary customers are PV module manufacturers and solar project developers seeking high‑purity recycled silicon and glass for sustainable production, as well as waste management firms handling end‑of‑life solar installations.
