Latest Patents

One of his latest patents is the "Preparation of thin film for solar cell using paste." This method involves creating a CIS-based or CIGS-based thin film for the light absorption layer of a solar cell. The process utilizes a paste made from precursors of copper, indium, selenium, and optional gallium in a solvent. This innovative approach minimizes raw material loss, avoids the production of toxic gases, and is suitable for large-scale film production at a low cost.

Another notable patent is the "Method for the production of dimethyl ether." This method includes separating a CO-rich stream from a crude product stream containing dimethyl ether and carbon monoxide obtained from a DME synthesis. The CO-rich stream is introduced to a reverse water gas shift reactor, where it reacts with hydrogen in the presence of an oxide catalyst, either zinc oxide or nickel oxide, to provide a CO-rich stream that is recycled back to the methanol synthesis step.
