Effective interfacial layer to enhance efficiency of polymer solar cells via solution-processed fullerene-surfactants

Chang-Zhi Li, +5 more
- 03 Apr 2012 - 
TL;DR: In this article, two methanol-soluble fullerene surfactants have been developed as interfacial layers for cathodes in polymer solar cells, which facilitate the tuning of cathode work function and extraction of electrons that significantly enhance open-circuit voltage and photocurrent generation.
Journal ArticleDOI

Crosslinkable hole-transporting materials for solution processed polymer light-emitting diodes

Fei Huang, +4 more
- 23 Sep 2008 - 
TL;DR: In this paper, a brief overview of the recent development of crosslinkable hole-transporting materials and their unique advantages in enhancing the performance of LEDs is provided, which greatly facilitates the subsequent processing of the emitting layer.
Journal ArticleDOI

Large Electro-optic Activity and Enhanced Thermal Stability from Diarylaminophenyl-Containing High-β Nonlinear Optical Chromophores

Yen-Ju Cheng, +11 more
- 08 Feb 2007 - 
TL;DR: Two series of highly efficient and thermally stable nonlinear optical chromophores based on the (4-diarylamino)phenyl electron donors have been synthesized and systematically investigated as discussed by the authors.
Journal ArticleDOI

Effects of Self-Assembled Monolayer Modification of Nickel Oxide Nanoparticles Layer on the Performance and Application of Inverted Perovskite Solar Cells

Qin Wang, +8 more
- 09 Oct 2017 - 
TL;DR: A series of benzoic acid selfassembled monolayers (SAMs) are used to passivate the surface defects of the NiOx NPs and found that 4-bromobenzoic Acid could effectively play the role of the surface passivation, resulting in more stable PSCs with enhanced power conversion efficiency (PCE) of 18.4 %, exceeding the control device PCE (15.5 %).
Journal ArticleDOI

Flexible and twistable non-volatile memory cell array with all-organic one diode–one resistor architecture

Yongsung Ji, +6 more
- 01 Nov 2013 - 
TL;DR: The study on integrated organic memory cell arrays suggests that the all-organic one diode-one resistor cell architecture is suitable for high-density flexible organic memory applications in the future.
