Abstract

Among alternative perovskite device architectures, mesoporous scaffolds based on metal oxide and carbon look highly promising due to their inherent high stability. In this study, the perovskite deposition has been realized on a 1.5 cm2 active surface area using inkjet infiltration through the mesoporous scaffold, affording a clean industrial process for large-scale and stable perovskite devices. A spectacular enhancement of photovoltaic performances from 10% to 14% was then obtained through the implementation of a maturation step. A study of the occurring mechanisms was conducted using a full set of characterization techniques including J-V measurements, UV–visible and PL spectroscopies, LBIC and PL imaging, XRD, and surface roughness measurements. In addition, the impact of this maturation step on the durability of the performances was investigated.

Abstract

A donor--acceptor dyad system involving tetrathiafulvalene (TTF) as donor attached by a flexible spacer to perylene-3,4:9,10-bis(dicarboximade) (PDI) as acceptor was synthesized and characterized. It was shown that the fluorescence emission intensity of the TTF-PDI dyad can be reversibly tuned depending on the oxidation states of the TTF unit.
