Theoretical Investigation of Hole Transporter Materials for Energy Devices

The Journal of Physical Chemistry C, 2015
We present combined MD-DFT calculations to investigate the electronic, optical, and charge-transport properties of six triphenylamine-based hole-transporter materials (HTMs) used in solid-state dye-sensitized solar cells (ssDSSC), including the state-of-the-art material in this field, 2,2?,7,7?-tetrakis(N,N-di-4-methoxyphenylamino)-9,9?-spirobifluorene

Electroluminescence of a Zinc Complex Exciplex with a Hole-Transporting Material

Russian Physics Journal, 2019
Results of theoretical and experimental studies of exciplex of a zinc complex Zn(DFP-SAMQ)2 with the hole-transporting layer of NPD are presented. It is shown that at least three different arrangements of Zn(DFP-SAMQ)2 and NPD molecules in the excited state result in the long-wavelength charge-transfer emission bands. At the same time, such systems are

Hole‐Transporting Materials for Perovskite Solar Cells

Asian Journal of Organic Chemistry, 2018
AbstractIn recent years, inorganic−organic metal halide perovskite solar cells (PSCs) have delivered power conversion efficiencies (PCE) beyond 22%, in which hole‐transporting materials (HTMs) play the key role to the improved photovoltaic performance and chemical stability.

Electrochemistry of some novel hole transport materials

Journal of Electroanalytical Chemistry, 2004
Several charge transfer agents have been investigated using cyclic voltammetry. We report multistep mechanisms involving both chemical and electrochemical steps, for the three compounds in the study. The overall mechanism consists of two quasi-reversible electron transfer events, each followed by a chemical step, an ECEC mechanism.

New branched hydrazones as hole transporting materials

Journal of Photochemistry and Photobiology A: Chemistry, 2005
Abstract The new hole transporting materials with molecules consisting of two hydrazone branches linked with flexible benzene ring and two hydroxyl groups containing central bridge were synthesized and investigated. These transporting materials are low molecular glasses and allow preparing stable to crystallization layers. Ionisation potential of the

Thiophene-based hydrazones as hole-transporting materials

Synthetic Metals, 2009
Abstract The synthesis, optical, thermal and photoelectrical properties of thiophene-based hydrazones are reported. The HOMO levels in a solid state of thiophene-based hydrazones measured by the electron photoemission technique are −5.25 eV and −5.28 eV.

Tetrathiafulvalene Derivatives as Hole-Transporting Materials in Perovskite Solar Cell

The Journal of Physical Chemistry A, 2022
Over a couple of decades perovskite solar cells have become a highly promising photovoltaic technology. Choosing a dopant-free Hole-Transporting Material (HTM) that offers protection to a perovskite layer from oxidation is one of the viable strategies while addressing the stability of perovskite solar cell.

Highly Efficient and Stable Perovskite Solar Cells Using a Dopant‐Free Inexpensive Small Molecule as the Hole‐Transporting Material

Advanced Energy Materials, 2018
The hole transporting layer (HTL) plays an important role in realizing efficient and stable perovskite solar cells (PSCs). In spite of intensive research efforts toward the development of HTL materials, low-cost, dopant-free hole transporting materials ...

Hole Transport in the InSbInAs material system

Solid State Communications, 1995
Abstract We discuss the scattering mechanisms limiting hole mobility in InAs, InSb and InAsSb. Transport in the binaries is limited by ionised impurity scattering at low temperatures and phonon scattering at high temperatures and in high purity material.
