Latest Patents

Among O Long's latest inventions is a method for the recycling of CdTe (Cadmium Telluride) photovoltaic waste. This comprehensive approach focuses on the extraction and reclamation of valuable metals from scrap CdTe photovoltaic cells and manufacturing waste. The patented process utilizes a leaching solution composed of nitric acid and water, allowing for the efficient separation of materials. The method involves skimming any plastic material from the leaching solution, separating the glass substrate from the liquid leachate, and electrolyzing the leachate to isolate cadmium (Cd) from tellurium (Te). This innovative technique allows for the cathodic deposition of tellurium while maintaining cadmium in solution.

Another related patent focuses on a similar process of recycling CdTe photovoltaic waste through a slightly different approach. This method also involves leaching the metals using dilute nitric acid, separating precipitated cadmium and tellurium from the leachate, and ultimately recovering the calcium-containing base used in the process.
