Bifacial passivation of Interlayers by Imidazole based small molecules as efficient hole transporting materials to enrich the performance of Perovskite Solar Cell
Abstract:
In recent days, conductive small organic molecular based hole transporting materials have become hot research in high performance perovskite solar cells. A set of novel Tetra-N-Phenylbenzidine based imidazole (TPD-IMI) derivatives were designed and synthesized as hole transporting materials for efficient perovskite solar cells. The photophysical properties, and their hole transporting performance have been investigated thoroughly. They have shown good thermal stability and hole mobility performance over the reference material. The enhanced efficiency with short circuit current has been obtained by the introduction of methoxy functionalities in the molecular structure.
