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

Posted on 17 Jan 09:34

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) has topped the record of the OPV devices. Those two materials 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.

 

Full name 3,9-bis(2-methylene-(3-(1,1-dicyanomethylene)-indanone))-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno[2,3-d:2’,3’-d’]-s-indaceno[1,2-b:5,6-b’]dithiophene
Structure chemical structure of ITIC
Synonyms ITIC
Chemical formula C94H82N4O2S4
CAS number n/a
Molecular weight 1427.94
HOMO / LUMO HOMO = -5.48 eV, LUMO = -3.83 eV

 

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 PBDB-T
Chemical formula (C68H78O2S8)n
CAS number n/a
Molecular weight M1001: MW = 66,759 / MN = 31,505 / PDI = 2.12
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 chemical structure of pce12, PBDB-T
Synonyms PDPP3T
Chemical formula (C50H72N2O2S3)n
CAS number 1198291-01-8
Molecular weight M991: MW = 117,406 / MN = 58,737 / PDI = 2.0
HOMO / LUMO HOMO = -5.17 eV, LUMO = -3.61 eV

New Materials Have Been Added to Our Two-Dimensional Material Collection!

Posted on 22 Dec 15:36

Reduced graphene oxide (rGO), a form of graphene oxide with oxygen-containing groups removed, has recently been added to our collection. This is available in chemically and thermally-reduced varieties, both of which offer improved electrical properties over graphene oxide.

In addition to this, pre-made solutions of graphene oxide and nitrogen-doped graphene oxide will be available early 2017.

Ossila Attend Inaugural Excilight Annual Meeting at the 16th Baltic Polymer Symposium

Posted on 30 Sep 15:54

 

The 16th Baltic Polymer Symposium (BPS 2016) was held from the 21st - 24th of September in Klaipėda, Lithuania, which is situated alongside the Baltic Sea. Two members of Team Ossila, Marco Colella and Dr. Nick Scarratt, were lucky enough to attend.

The symposium covered all aspects of modern polymer science, including synthesis, processing, composites, nanotechnologies and much more.

Our very own Marco Colella also attended the first ever annual Excilight day that took place as part of the symposium in Klaipėda between the 20th and 21st of September.

Marco reported: "We had such a great time. Every PhD student of the consortium (15 in total) presented their work in progress. The project has already achieved some of the set goals and the science so far looks very promising."

Marco is picture below in the group photo taken at the meeting.
