Abstract The fill factor (FF) as an important photovoltaic parameter is related to the property of transport layers and active layers for organic solar cells (OSCs). Herein, we propose a simple method to improve FF by using inorganic-organic composite hole transport layer (HTL) in OSCs. Through incorporating inorganic metal oxide, vanadium pentoxide (

Efficient hole injection by doping of hexaazatriphenylene hexacarbonitrile in hole transport layer
Thin Solid Films, 2009Abstract Hexaazatriphenylene-hexacarbonitrile (HAT) was used as a dopant in hole transport layer and hole injection properties of the HAT doped hole transport layer were studied. Hole injection was greatly improved by doping of the HAT in the hole transport material and a driving voltage was lowered by more than 3 V.

2006 European Solid-State Device Research Conference, 2006
Insertion of hole-blocking layer (HBL) between the hole-transporting layer (HTL) and hole-injection layer for tris-(8-hydroxyquinoline) aluminum (Alq3)-based organic light-emitting device is shown to improve the current efficiency by 30%. The improvement was attributed to the better electron-hole balance in the device.

An Alternative Hole Transport Layer for Both ITO‐ and Graphene‐Based Organic Solar Cells
Advanced Energy Materials, 2014 A new type of hole transport layer, polythiophene derivative, for organic solar cells is introduced, which shows similar transparency and good wettability for both indium tin oxide (ITO) and graphene compared to poly(3,4- ethylenedioxythiophene):poly ...

Compact Layer Free Perovskite Solar Cells with a High-Mobility Hole-Transporting Layer
ACS Applied Materials & Interfaces, 2016A high-mobility diketopyrrolopyrrole-based copolymer (P) was employed in compact layer free CH3NH3PbI3 perovskite solar cells as a hole-transporting layer (HTL). By using the P-HTL, the 6.62% device efficiency with conventional poly-3-hexylthiophene was increased to 10.80% in the simple device configuration (ITO/CH3NH3PbI3/HTL/MoO3/Ag).

The Characteristic of Organic Hole-Only Devices Based on Crosslinked Hole-Transport Layer
2014 International Symposium on Computer, Consumer and Control, 2014The preparation of organic electronics devices via solution process based on insoluble layer as well as it's preparation mechanism via oxetane ring-opening polymerisation has been known. This paper reports the electrical characteristic of the devices due to this polymerisation mechanism as oxidative, trityl, and photo cross linking.

Enhanced Hole Transport in Polyfluorene Polymer by Using Hole Injection Layer
2014Hole transport in poly(9,9-dioctylfluorene) (PFO) are measured by performing current density- voltage (J-V) measurements as a function of temperatures. For the J–V measurements, F4TCNQ is used as hole injection layer (HIL). Two different devices of PFO polymer are fabricated F4TCNQ having device configuration ITO/PFO/Au (with interface modification ...

2015 International Conference on Quality in Research (QiR), 2015
In this paper we study the effect of Hole Transport Layer NPB (N,N′-diphenyl-N,N′-bis(1-naphtyl)-1,1′-biphenyl-4,4″-diamine) and Electron Transport Layer on the performance of a single layer of Blue Organic Light Emitting Diode. Three different structures are analyzed and are compared to the reference structure.

Hole transporting layers in printable solar cells
2017The incessant evolution of organic and hybrid solar cells has demonstrated that a multilayer architecture is required for an optimum device functioning. Although more attention has been traditionally focused on the active layer materials, it is the interfacial materials, placed between the electrodes and the active region, which might play some of the ...
