PNDIT-F3N

n-Type Semiconducting Polymer for Electron Transport Layer Alcohol soluble cathode interlayer material for polymer organic solar cells and perovskite solar cells Specifications | MSDS | Literature and Reviews | Related Products | Technical Support PNDIT-F3N is an alternating n-type conjugated copolymer of electron deficient naphthalene diimide and electron rich fluorene backbone units. As a semiconducting polymer, it is used in high performance polymer organic solar cells as an electron transport layer (ETL) interface between the active layer and the cathode. The presence of amine groups on the side chains of the polymer can n-dope the acceptor in contact (i.e. to improve the electron extraction properties) and also induce self-doping to generate highly conductive ETLs with reduced ohmic loss for electron transport and extraction. Power conversion efficiency of 19.32% was achieved for a ternary active layer D18:BTP-3FBr:IDIC based device using PNDIT-F3N as the electron transport and PEDOT:PSS as the hole transport. By mixing two electron transport materials, PNDIT-F3N and PDINN (4:1 wt%), the mixed electron transport layer shows better energy level alignment with the active layer and an improved film morphology, leading to better charge selectivity, enhanced charge extraction, suppressed exciton recombination, and finally a boosted PCE in the PM6:Y6-based solar cells. Additionaly, a polymer organic solar device based on PM6:Y6 as the active layer and PNDIT-F3N and PDIN (3:2 wt%) as the hybrid cathode interlayer yielded higher FF of 74.45% and JSC of 27.12 mA cm2, resulting in a high PCE of 17.4%.
