Hole transport layers deposited by magnetron sputtering

III SEVEN INTERNATIONAL MULTIDISCIPLINARY CONGRESS, 2023
Nickel oxide films have been widely studied as hole transport layers in perovskite solar cells because they present good chemical stability and nickel is abundant in nature. In this study, films were deposited using Magnetron Sputtering with a pulsed source.

Novel approach toward hole-transporting layer doped by hydrophobic Lewis acid through infiltrated diffusion doping for perovskite solar cells

Nano Energy, 2020
In this work, an alternative processing route for doping of hole-transporting layer (HTL) with improved hole extraction and passivation of anionic Pb–I antisite defects at the perovskite/HTL heterojunction is reported for the first time in perovskite ...

Enhanced hole transport in C60-doped hole transport layer

Applied Physics Letters, 2006
The carrier mobility of C60-doped hole transport layer was investigated according to the C60 content. The addition of C60 in the 1, 3, 5-tris (N, N-bis-(4, 5-methoxyphenyl)-aminophenyl) benzol (TDAPB) hole transport material resulted in the increase of hole mobility of TDAPB.

Ambipolar Charge Transport in “Traditional” Organic Hole Transport Layers

Advanced Materials, 2012
Organic semiconductors are often labeled as electron or hole transport materials due to the primary role they perform in devices. However, despite these labels we have shown using time-of-flight that two of the traditional "hole transport materials" TPD and NPB are actually excellent electron transporters the electron transport properties of which are ...

Organic light-emitting devices with a hole-blocking layer inserted between the hole-injection layer and hole-transporting layer

Applied Physics Letters, 2006
A hole-blocking layer (HBL), 2,9-dimethyl-4, 7-diphenylphenanthroline (BCP), was incorporated between the hole-transporting layer (HTL) and hole-injection layer for a tris-(8-hydroxyqunoline) aluminum-based organic light-emitting device. Such a structure helps to reduce the hole-leakage to the cathode resulting in improved current efficiency.

Enhanced hole injection and transport in molybdenum-dioxide-doped organic hole-transporting layers

Journal of Applied Physics, 2008
We have found that molybdenum dioxide (MoO2) is an excellent dopant for enhancing electrical conductivities in organic hole-transporting layers. We fabricated hole-only devices with an alpha-sexithiophene (α-6T) layer doped with MoO2 at various concentrations to investigate how doping MoO2 into the α-6T layers influences the hole-injection and hole ...

A modeled perovskite solar cell structure with a Cu2O hole-transporting layer enabling over 20% efficiency by low-cost low-temperature processing

Journal of Physics and Chemistry of Solids, 2019
We introduce Cu2O as a hole-transporting material in perovskite solar cells. Device modeling with a configuration of glass/fluorine-doped tin oxide/ZnO/perovskite/Cu2O/carbon was performed by SCAPS, a solar cell capacitance simulator.

Organic Ionic Plastic Crystals as Hole Transporting Layer for Stable and Efficient Perovskite Solar Cells

Advanced Functional Materials, 2020
Organic ionic plastic crystals (OIPCs) are synthesized through a simple metal‐free, cost‐effective approach. The strategized synchronization of electron‐rich phenoxazine with benzimidazolium iodide (OIPC‐I) and bromide (OIPC‐Br) salts lead to enhanced ...
