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
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}
Structure
Synonyms	PDPP3T
Chemical formula	(C50H72N2O2S3)n
CAS number	1198291-01-8
Molecular weight	M991: MW = 66,759 / MN = 31,505 / PDI = 2.12
HOMO / LUMO	HOMO = -5.17 eV, LUMO = -3.61 eV
