Enhancing Stability of Layered Double Perovskites With a Naphthalene Diimide Spacer Toward Photoelectrochemical Application

ABSTRACT Lead‐free layered hybrid double perovskites (LHDPs) promise stable, non‐toxic optoelectronic devices, but operating these materials in applications with a direct semiconductor/water interface remains a challenge. We show that a bulky, hydrophobic naphthalene diimide dica...

Diketopyrrolopyrrole‐Based Cation as a Semiconducting Spacer in Layered Perovskite

ABSTRACT Incorporating π‐conjugated organic spacers in layered “2D” perovskites in order to extend solar light harvesting has remained a challenge, as typically‐incorporated spacers (e.g. phenethylammonium, PEA + ) do not absorb deep into the visible spectrum. Here, we introduce...
