Boost the performance of inverted perovskite solar cells with PEDOT:PSS/Graphene quantum dots composite hole transporting layer

, 2020
The inverted p-i-n structure perovskite solar cells show great potential in wearable devices and flexible solar cells. Yet the commonly used PEDOT:PSS hole transporting layer still needs to be optimized in order to pursue superior performances.

Study of Electron Transport Layer‐Free and Hole Transport Layer‐Free Inverted Perovskite Solar Cells

Solar RRL, 2021
The selective contacts in perovskite solar cells play a major role in solar cell (SC) performance and optimization. Herein, the inverted architecture is focused on, where systematically the electron transport layer (ETL) and the hole transport layer (HTL) from the SC structure are eliminated.

Atomic layer deposition of NiO hole-transporting layers for polymer solar cells

Nanotechnology, 2015
NiO is an attractive hole-transporting material for polymer solar cells (PSCs) owing to its excellent stability and electrical/optical properties. This study demonstrates, for the first time, fabrication of uniform, defect-free, and conformal NiO ultra-thin films for use as hole-transporting layers (HTLs) in PSCs by atomic layer deposition (ALD ...

Improved organic light-emitting devices with tunable IV by inserting a hole-blocking layer between hole-injecting layer and hole-transporting layer

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.

Compact Layer Free Perovskite Solar Cells with a High-Mobility Hole-Transporting Layer

ACS Applied Materials & Interfaces, 2016
A 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).
