应用

PFN-Br是可溶液加工的共轭聚电解质材料，可用作高性能有机光伏电池(OPV)和有机发光二极管(OLED)的界面层，提高其界面性能。 [1][2][3]

采用PFN-Br界面层的有机太阳能电池在短路电流密度、开路电压、填充因子参数的性能上都有增强，倒置OPV的效率提高。[3]这是因为PFN-Br使ZnO电子提取层和活性层之间接触更易，电子提取层和活性层之间的界面结合性更好，并通过抑制双分子复合增强电荷传输。

最近报道的能量转换效率达17.3%的有机太阳能电池也采用了PFN-Br材料，将其旋涂在ZnO上以提高界面性能。[1]

Questions

1–3 of 3 Questions  

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

    1 answer

    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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

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

    1 answer

    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 answer

    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.
