PM7 Chemical Properties, Uses, Production
Description
PBDB-T-2Cl, also known as PM7, is part of the PBDB-T polymer family. It has a high OPV device performance, withreported efficiencies exceeding 12%. PSCs based onPBDB-T-2Cl as the donor and ITIC-2F as the acceptor have achieved a power conversion efficiency (PCE) of over 14% [2].
Uses
High-Efficiency Organic Solar Cells (OPVs)
Polymeric donor material
LUMO=3.57 eV
HOMO=5.32 eV
OPV Device Performance :
PBDB-T-2Cl:IT-4F
Voc= 0.86V
Jsc= 21.46 mA/cm2
FF= 0.75
PCE=13.9%
PBDB-T-2Cl (or PM7) is a wide bandgap polymer donor (n-type semiconductor) containing chlorinated thienyl benzodithiophene (BDT-2Cl) used in high performance polymer solar cells (PSCs). PBDB-T-2Cl-based devices exhibit higher open circuit voltage (Voc) than the PBDB-T-2F-based devices, due to lower molecular energy levels of PBDB-T-2Cl, and leading to an outstanding power conversion efficiency of over 14%.
In general, chlorination is more effective than fluorination in downshifting the molecular energy levels and broadening the absorption spectra.
