Optical Alignment of Si-Containing Nanodomains Formed by Photoresponsive Amorphous Block Copolymer Thin FilmsOptical Alignment of Si-Containing Nanodomains Formed by Photoresponsive Amorphous Block Copolymer Thin Films

A series of amorphous block copolymers (BCPs), consisting of a low-glass-transition polydimethylsiloxane (PDMS) block associated with a photoresponsive azobenzene-containing poly(disperse red 1...

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

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...

AFM images of height and phase of fluorinated polymer blend films at different terpolymer/copolymer ratios (100/0, 95/5, 90/10, 80/20, 70/30, 0/100) (tapping mode, 1 µm × 1 µm scan area).High and Temperature-Independent Dielectric Constant Dielectrics from PVDF-Based Terpolymer and Copolymer Blends

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...

Synthesis of Carboxyl-EDOT as a Versatile Addition and Additive to PEDOT:PSSSynthesis of Carboxyl-EDOT as a Versatile Addition and Additive to PEDOT:PSS

Two-step synthesis of EDOT (3,4-ethylenedioxythiophene) derivate bearing a carboxylic acid group (carboxyl-EDOT) is presented. This reactive monomer has been copolymerized with EDOT to afford PEDOT...

Post-functionalization of polyvinylcarbazoles: An open route towards hole transporting materials for perovskite solar cellsPost-functionalization of polyvinylcarbazoles: An open route towards hole transporting materials for perovskite solar cells

We report on the potential of tuning poly(9-vinylcarbazole) (PVK) properties through functionalization for an application as hole transport material (HTM) for perovskite solar cells (PSCs). The...
