BTP-4Cl-12

Description

** While supplies last

BTP-4Cl-12 is an analog to Y7 with longer alkyl chains on its pyrrole rings. This derivative improves the processability of its predecessor, improving performances. A PCE of over 17% was reported using the donor polymer PBDB-T-2F . A device certified by the National Institute of Metrology, China (NIM) registered a PCE of 16.7%.
