Title (EN) METHODS FOR PRODUCING LIGHT-ABSORBING MATERIALS WITH PEROVSKITE STRUCTURE AND LIQUID POLYHALIDES OF VARIABLE COMPOSITION FOR THEIR IMPLEMENTATION
(FR) PROCÉDÉS DE PRODUCTION DE MATÉRIAUX ABSORBANT LA LUMIÈRE AVEC STRUCTURE DE PÉROVSKITE ET POLYHALOGÉNURES LIQUIDES DE COMPOSITION VARIABLE POUR LEUR MISE EN ŒUVRE
Abstract:
(EN) The invention relates to the organic-inorganic light-absorbing materials with perovskite structure, being used in perovskite solar cells production. The objective of the invention is to provide the possibility of obtaining perovskite using precursors that are in a liquid state without the use of additional substances and reagents. The concept of the invention is based on the fact that a light-absorbing material with perovskite structure with general formula ADB3, where A stands for methylammonium MA+ (CH3NH3+), formamidinium, FA+ ((NH2)2CH+), guanidinium Gua (C(NH2)3+), cesium Cs+ or a mixture thereof, B stands for Cl-, Br-, I- or a mixture thereof, while the component D represents Sn, Pb, Bi or a mixture thereof, is obtained by mixing composition AB-nB2 and a component containing D, where the component containing D is chosen from elemental Sn, Pb, Bi and/or their salts, mixtures, alloys, whereas the composition AB-nB2 is deposited onto the component D followed by subsequent removal of the excessive components, n is greater than or equal to one, the component B2 represents Cl2, Br2, I2 or a mixture thereof. 3 c, 7 C.
(FR) La présente invention concerne des matériaux absorbant la lumière organiques-inorganiques avec une structure de pérovskite, étant utilisés dans la production de cellules solaires en pérovskite. L'objectif de l'invention est d'offrir la possibilité d'obtenir de la pérovskite au moyen de précurseurs qui sont à l'état liquide sans utiliser des substances et réactifs supplémentaires. Le concept de l'invention est basé sur le fait qu'un matériau absorbant la lumière ayant une structure de pérovskite de formule générale ADB3, où A désigne méthylammonium MA+ (CH3NH3 +), formamidinium, FA+ ((NH2)2CH+), guanidinium Gua (C(NH2)3 +), césium Cs+ ou un mélange de ceux-ci, B désigne Cl-, Br-, I- ou un mélange de ceux-ci, tandis que le composant D représente Sn, Pb, Bi ou un mélange de ceux-ci, est obtenu par mélange de la composition AB-nB2 et d'un composant contenant D, le composant contenant D étant choisi parmi Sn, Pb, Bi élémentaires et/ou leurs sels, mélanges, alliages, tandis que la composition AB-nB2 est déposée sur le composant D suivi d'une élimination ultérieure des composants en excès, n est supérieur ou égal à un, le composant B2 représente Cl2, Br2, I2 ou un mélange de ceux-ci.
