Highly Conductive PEDOT:PSS Electrode with Optimized Solvent and Thermal Post-Treatment for ITO-Free Organic Solar Cells
Yong Hyun Kim,Christoph Sachse,Michael L. Machala,Christian Albrecht May,Lars Müller-Meskamp,Karl Leo +5 more
TL;DR: In this article, a solvent post-treatment method was used to optimize poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) films as stand-alone electrodes for organic solar cells.
Journal ArticleDOI
Efficiency enhancement of organic solar cells by fabricating periodic surface textures using direct laser interference patterning.
Lars Müller-Meskamp,Yong Hyun Kim,Teja Roch,Simone Hofmann,Reinhard Scholz,Sebastian Eckardt,Karl Leo,Andrés Fabián Lasagni +7 more
TL;DR: Direct laser interference patterning is used to fabricate large area, two-dimensional periodic surface patterns on polyethylene terephthalate (PET) substrates to enhance the performance of ZnPc:C60 solar cells by light concentration in the absorber layer.
Journal ArticleDOI
Nano-particle based scattering layers for optical efficiency enhancement of organic light-emitting diodes and organic solar cells
Hong-Wei Chang,Jonghee Lee,Simone Hofmann,Yong Hyun Kim,Lars Müller-Meskamp,Björn Lüssem,Chung-Chih Wu,Karl Leo,Malte C. Gather +8 more
TL;DR: In this paper, a solution-processed nano-particle-based light-scattering films close to the active region of organic semiconductor devices are used to extract light that would otherwise remain trapped in the device.
Journal ArticleDOI
Achieving High Efficiency and Improved Stability in ITO‐Free Transparent Organic Light‐Emitting Diodes with Conductive Polymer Electrodes
Yong Hyun Kim,Jonghee Lee,Jonghee Lee,Simone Hofmann,Malte C. Gather,Lars Müller-Meskamp,Karl Leo +6 more
TL;DR: In this paper, an efficient transparent organic light-emitting diodes (OLEDs) with improved stability based on conductive, transparent poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) electrodes are reported.
Journal ArticleDOI
