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.
