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 ...
