Creating a Record-Breaking Solar Cell

The innovative method allows forming the electrode layer as thin as 1-2 nm, evenly covering even rough surfaces of tandem architectures.

Tandem perovskite-CIGS solar cells, produced as a result of the collaboration between Lithuanian and German researchers, have reached an efficiency of 23.26 per cent, which currently is a world record value in this type of cells. One reason for the success lies in the cell's intermediate layer of organic molecules:

Charge Fluctuations, a new Property in Superconductors
Superconductivity enables us to prevent loss when transporting energy from power plants to our homes. However, to do this, the lines must be cooled to temperatures that are so low as to make large-scale use of superconductors uneconomic at present. Therefore, in laboratories across the world researchers are
