Solution-processed bulk heterojunction solar cells based on BF_2-hydroxychalcone complexest

摘要

2'-Hydroxychalcone derivatives featuring a triphenylamine terminal unit were synthesized in one step and behaved as effective ligands for borondifluoride coordination, enabling the straightforward generation of D-A molecules with strong absorption. Solution-processed solar cells based on these complexes and PC_61BM showed a PCE of 1.13%.
