Cesium helps perovskite solar last longer

Cesium iodide can improve the stability and efficiency of certain perovskite solar cells, according to researchers at Kanazawa University. Added to cells of the ‘MAPbI3‘ perovskite structure, by alternately depositing thin layers of MAPbI3 and CsI, atoms from Cs migrate and become intercalated into the crystal lattice (see diagram). “Our approach allowed us to produce layers ...

TUM team ASIC implements post-quantum cryptography

A team at the Technical University of Munich (TUM) has designed and commissioned the production of a computer chip that implements post-quantum cryptography very efficiently. Such chips could provide protection against future hacker attacks using quantum computers. The researchers also incorporated hardware trojans in the chip in order to study methods for detecting this type ...
