Yuanhao’s work on “Triplet Management at Ligand-Perovskite Interface to Enhanced Photovoltaics Performance” has been published in ACS Energy Letters. Congratulations!
We report the observation of charge transfer from FAPbI3 to the triplet state of a pyrene (Pyr)-based cationic ligand. Interestingly, a subtle structural modification from Pyr to the triphenylene (TP) core gave rise to shallower triplets that prohibit triplet electron transfer. This strategy has led to an enhanced efficiency of 24.69% from 23.10%. The devices retained above 80% initial PCE after 4000 h of light soaking. Read the story here.
