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.
