Description générale

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Electron transport organic materials have the chemical functionality to transport electrons and are used as electron transport layer in OLED devices. Click here for more information.

Application

PFN-Br is a solution processible, conjugated polymer electrolyte used as interficial layer in high performance organic photovoltaic cells (OPV) and organic light emitting diodes (OLED) to improve the interfacial properties.[1][2][3]

OPV devices with PFN-Br interfacial layer showed overall enhanced short-circuit current density, open-circuit voltage, fill factor and corresponding high efficiency in the inverted OPVs.[3] This was attributed to the good contact between ZnO electron extraction layer and the active layer, good interface adhesion between the electron extraction layer and active layer, and enhanced charge transport via suppressed bimolecular recombination.

Recent report of OPV with a record energy conversion efficiency of 17.3% also utilized PFN-Br, spin-coated on top of ZnO to improve the interfacial properties.[1]

Voc=1.642 V
Jsc=14.35 mA/cm2
FF=73.7%
PCE=17.3%

PFN-Br finds application in a wide range of areas:
  • OPV interficial layer (metalic oxide compact layer)
  • OLED electron transport layer
  • Perovskite solar cells
  • Flexible printed electronics
  • Cationic polymer electrolyte
  • Anion exchange material
  • Light emitting electrochemical cells

Questions

1–3 sur 3 questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 réponse

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 réponse

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  3. What are the end-capping groups on this polymer?

    1 réponse

    1. There is no termination group attached to the ends of the polymer. It is simply hydrogen attached to the aromatic ring, rather than another monomeric unit.
