Synthetic approaches to organic hole transport materials for wide band-gap perovskite solar cells

This contribution is focused on the synthesis and characterization of triarylamine-based hole transport materials (HTMs) for transparent perovskite solar cells (10.1002/aenm.202200402). Aided by ab-initio simulations, we have designed promising derivatives with appropriate frontier orbitals matching (labs <450 nm, Eg> 2.5 eV) with wide band-gap perovskites, and screened low-impacting reaction media like glycerol (10.1007/s10311-006-0080-z) for the key palladium-catalyzed C-C coupling steps.
