Title (EN) DOPANT-FREE INEXPENSIVE HOLE TRANSPORTING MATERIALS FOR HIGHLY EFFICIENT AND STABLE PEROVSKITE SOLAR CELLS
(FR) MATÉRIAUX DE TRANSPORT DE TROUS PEU COÛTEUX EXEMPTS DE DOPANT POUR CELLULES SOLAIRES EN PÉROVSKITE HAUTEMENT EFFICACES ET STABLES
Abstract:
(EN) Disclosed herein are novel hole transporting materials comprising polycyclic heteroaromatic hydrocarbon compounds that are easy to synthesize and inexpensive. The hole transporting materials of the present disclosure have high hole mobility and thus do not require any doping. The hole transporting materials of the present disclosure also have matching frontier orbitals when used in devices with the perovskite and cathodes, facilitating hole migration across perovskite/hole transporting layers and hole transporting layer/cathode interfaces. The hole transporting materials of the present disclosure can further be hydrophobic with no moisture attracting atoms. The hole transporting materials can be used to form dense and uniform films on perovskite, and combined with hydrophobicity, form an excellent moisture barrier for the perovskite. With the present disclosure compound as the hole transporting layer in a perovskite solar cell, highly stable and highly efficient and inexpensive solar cells can be achieved.
(FR) L'invention concerne de nouveaux matériaux de transport de trous comprenant des composés hydrocarbonés hétéroaromatiques polycycliques qui sont faciles à synthétiser et peu coûteux. Les matériaux de transport de trous de la présente invention présentent une mobilité de trous élevée et ne nécessitent donc aucun dopage. Les matériaux de transport de trous de la présente invention ont également des orbitales frontalières correspondantes lorsqu'elles sont utilisées dans des dispositifs avec la pérovskite et les cathodes, facilitant la migration de trous à travers les couches de transport de pérovskite/trous et les interfaces couche/cathode de transport de trous. Les matériaux de transport de trous de la présente invention peuvent en outre être hydrophobes sans atomes d'attraction d'humidité. Les matériaux de transport de trous peuvent être utilisés pour former des films denses et uniformes sur pérovskite, et combinés avec une hydrophobicité, forment une excellente barrière contre l'humidité pour la pérovskite. Avec le composé de la présente invention en tant que couche de transport de trous dans une cellule solaire en pérovskite, des cellules solaires hautement stables et hautement efficaces et peu coûteuses peuvent être obtenues.
