Title
(EN) BANDGAP-TUNABLE PEROVSKITE MATERIALS AND METHODS OF MAKING THE SAME
(FR) MATÉRIAUX DE PÉROVSKITE À BANDE INTERDITE ACCORDABLE ET LEURS PROCÉDÉS DE FABRICATION
Abstract
(EN)
Bandgap-tunable perovskite compositions are provided having the formula CsPb(AxBy)3, wherein A and B are each a halogen. The mixed halide perovskite composition has a morphology which suppresses phase segregation to stabilize a tuned bandgap of the mixed halide perovskite composition. For example, the perovskite may be in the form of nanocrystals embedded in a non-perovskite matrix, which, for example, may have the formula Cs4Pb(AxBy)6, wherein A and B are each a halogen. Solar cells and light-emitting diodes comprising the mixed perovskite compositions are also provided.
(FR)
L'invention concerne des compositions de pérovskite à bande interdite accordable de la formule CsPb(AxBy)3, dans laquelle A et B sont individuellement un halogène. La composition mixte de pérovskite et d'halogénure a une morphologie qui supprime la ségrégation de phase de façon à stabiliser une bande interdite accordée de la composition mixte de pérovskite et d'halogénure. Par exemple, la pérovskite peut se présenter sous la forme de nanocristaux intégrés dans une matrice autre que de pérovskite, qui, par exemple, peuvent avoir la formule Cs4Pb(AxBy)6, dans laquelle A et B sont individuellement un halogène. L'invention concerne également des cellules solaires et des diodes électroluminescentes comprenant les compositions mixtes de pérovskite.
