The concept of “lattice matching” is a true baseline to assemble and interlock perovskite semiconductor materials leading to stable and efficient solar cells. Jacky Even, Professor at INSA Rennes (FOTON Institute – UMR CNRS 6082, CNRS, INSA Rennes, University of Rennes) cosigned with Professor Aditya Mohite (Rice University, USA) the work leading to a publication in the journal Science.

This article in collaboration with Claudine Katan (Institut des Sciences Chimiques de Rennes UMR 6226, CNRS, University of Rennes) crowns the work of the Rennes team Foton/ISCR.

The cover of the Science Journal illustrates the concept of “lattice matching” introduced by Jacky Even, which makes it possible to assemble the different forms of perovskite materials to associate performance and stability. Adding seeds of specifically designed 2D perovskites to the precursors of FAPbI3 leads to efficient and durable FAPbI3 perovskite solar cells.
