Exciton-band tuning induced by the width of the cation in 2D lead iodide perovskite hybrids

The Pb–I–Pb bond angle in 2D A2PbI4 perovskites, previously shown to be correlated to the exciton energy, can be tuned by changing the width of the organic A cation, at least within a limited series of compounds.

The role of dipole moment in two fused-ring electron acceptor and one polymer donor based ternary organic solar cells

The dipole moment of FREAs’ terminals has been unveiled as an important factor and its working mechanism has been thoroughly investigated. Our results demonstrate that the dipole moment should also be taken into account in designing ternary OSCs.

Efficient as-cast thick film small-molecule organic solar cell with less fluorination on the donor

Less fluorination, better performance! Devices based on DI3T-1F:PC71BM and DI3T-2F:PC71BM are fabricated for thick-film small molecule-solar cells (SMSCs). Indeed, the devices based on DI3T-1F the devices based on DI3T-1F show a better tolerance to thickness, giving PCE of 8.33% with ∼150 nm, and 5.43% with ∼300 nm, which are 14% and 50% higher than those of DI3T-2F, respectively.

About this collection

Welcome to Materials Chemistry Frontiers themed collection on “organic electronics”.

The impressive development of organic electronics has led to a growing demand of highly efficient organic semiconductors adapted to their use in specific devices including organic light-emitting diodes, organic field-effect transistors, organic photovoltaics and organic biosensors.

The complementarity between chemistry and physics is at the origin of the emergence of organic electronic technologies. Its two pillars, molecular design and devices engineering, have allowed to reach more and more efficient electronic devices over the years. This web theme covers the recent progress on conjugated functional materials for various organic electronic applications and aims to show the importance of complementarity between chemistry and physics.

Guest Editors: Nicolas Leclerc (Université de Strasbourg, CNRS), Zuo-Quan Jiang (Soochow University) and Cyril Poriel (Université de Rennes, CNRS)

More articles will be added as soon as they are published.
