Q Cells, German researchers claim 28.7% efficiency for 2T perovskite-silicon tandem solar cell
The Korean manufacturer and the German research centre were able to improve the performance of their jointly developed tandem solar cell by almost one percentage point.
Doped carbon for a reliable lithium sulfur battery
Scientists in South Korea developed a porous carbon material that, when applied as a coating to the separator film in a lithium-sulfur battery, was shown to reduce an unwanted side effect and improve the battery’s performance and reliability. The coating is based on methylene blue, a type of salt commonly used in textile dying.
