Recent advances on phenoxazine-based hole transporting molecules for perovskite solar cells
Résumé
SpiroOMeTAD is a well-recognized hole-transport materials for perovskite solar cells (PSCs). Besides, due to a complex synthesis, this compound is costly and alternatives to this structure are thus actively researched. With aim at developing low-cost hole-transport materials while maintaining an excellent hole-transport ability, phenoxazine has been identified as an appealing candidate. In this review, an overview of the phenoxazine-based hole-transport materials developed to date for perovskite solar cells is provided.
