p-Doping of a Hole Transport Material via a Poly(ionic liquid) for over 20% Efficiency and Hysteresis-Free Perovskite Solar CellsHomepage

An efficient metal-free formulation of a hole transport material (HTM) based on an ionic liquid polymer is developed for n–i–p perovskite solar cells (PSCs), to address reproducibility issues related to the use of complex dopant mixtures based on lithium salts and cobalt coordination complexes. The conductivity of the HTM is thus significantly improved by 4 orders of magnitude, up to 1.9 ×...

High and Temperature-Independent Dielectric Constant Dielectrics from PVDF-Based Terpolymer and Copolymer BlendsHomepage

Relaxor ferroelectric polymers exhibit high k at their structural phase transition around room temperature. They are particularly attractive as gate dielectric in organic field effect transistor (OFET). Nevertheless, their applications are limited due to their low thermal stability. A polymer blend system with a high and thermally stable dielectric constant is demonstrated by mixing terpolymer...

Photopatternable Highk Fluoropolymer Dielectrics Bearing Pendent Azido GroupsHomepage

Photopatternable fluoropolymers with high dielectric constant were prepared by direct azidation of commercially available poly(vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene). The produced fluoropolymers exhibit very high dielectric constant, while being photopatternable without the use of any additives. These cross-linked polymers appear to have reduced crystallinity compared to...

Introducing Functionality to Fluorinated Electroactive PolymersHomepage

Fluorinated electroactive polymers (FEPs) are among the most interesting insulating materials for the production of organic electronic devices. Their ability to tune their response to an applied electric fi eld makes them appropriate for vastly di ff erent applications in electronics. However, due to the chemical inertness of such polymers and the rather complex synthetic processes required for...
