Ossila FACT Box Guides Us to Highest PCDTBT Efficiency Yet

Posted on Fri, Jun 13, 2014 by Jack Stephenson

Update - 2017: Please note that as of 2017 the Ossila FACT System has been discontinued.


Congratulations and a big thanks to Andy Parnell and the rest of our collaborators on their latest publication in Nature Scientific Reports, Molecular weight dependent vertical composition profiles of PCDTBT:PC71BM blends for organic photovoltaics.

By using neutron scattering Andy and the team has shown that high molecular weight can create interface enrichment layers to the benefit of performance and has helped guide us to our highest efficiency yet for PCDTBT. The Ossila FACT System was used to characterise the OFET mobility of the polymers.

  • James Kingsley will be talking about this work at the upcoming SuperSolar Meeting in Sheffield.
  • OFET characterisations was carried out using the Ossila FACT system which will be available to view at the SuperSolar Meeting and also the UK Semiconductors Conference (Sheffield) and the Fall EMRS Conference (Warsaw).
  • The work was carried out using our pixelated cathode OPV substrates and spin coater which will also be present at SuperSolar, UK Semiconductors and EMRS.
