PDPP3T, PBDB-T and ITIC Added to our OPV Materials

Posted on Tue, Jan 17, 2017

We constantly update our OPV materials catalogue so we can be at the frontier of organic photovoltaic research, bringing you new materials for your research interests. 

With PCE over 12%, ITIC (a small molecule semiconductor) together with PBDB-T (PCE12) have topped the record of the OPV devices. Both these materials, along with PDPP3T, are now available from Ossila. See below for a summary of the materials.

ITIC

ITIC shows strong and broad absorption characteristics in the visible to near-infrared regions, and appropriate energy levels matched with low-band gap donor polymers.

See ITIC product page for full details.

 

PBDB-T (PCE12)

PBDB-T (PCE12) is one of the top donor materials for OPVs. PCEs over 12% were reported with excellent thermal stability [2,3]. With matching HOMO energy levels, PBDB-T could also be potentially used as a hole-transport layer material (HTL) for perovskite solar cells.

 

Full name Poly[(2,6-(4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)-benzo[1,2-b:4,5-b’]dithiophene))-alt-(5,5-(1’,3’-di-2-thienyl-5’,7’-bis(2-ethylhexyl)benzo[1’,2’-c:4’,5’-c’]dithiophene-4,8-dione)]
Structure chemical structure of pce12, PBDB-T
Synonyms PCE12, PBDB-T
Chemical formula (C68H78O2S8)n
CAS number 145929-80-4
Molecular weight M1001: MW = 117,406 / MN = 58,737 / PDI = 2.0
HOMO / LUMO HOMO = -5.33 eV, LUMO = -2.92 eV

 

See PBDB-T product page for full details.

 

PDPP3T

PDPP3T can be used as an active-layer material for OPV and OFET devices. Being electron-rich, it is also used as an effective spiro-OMeTAD replacement HTL material for perovskite solar cells.

 

Full name Poly{2,2′-[(2,5-bis(2-hexyldecyl)-3,6-dioxo-2,3,5,6- tetrahydropyrrolo[3,4-c ]pyrrole-1,4-diyl)dithiophene]- 5,5′-diyl-alt-thiophen-2,5-diyl}
