Journal ArticleDOI

Room-temperature, solution-processable organic electron extraction layer for high-performance planar heterojunction perovskite solar cells

Jong H. Kim, +4 more
- 15 Oct 2015 - 
TL;DR: The potential of low-temperature processed organic EEL to replace transition metal oxide-based interlayers for highly printing compatible PVSCs with high-performance is shown.
Journal ArticleDOI

Polymer triplet energy levels need not limit photocurrent collection in organic solar cells.

Cody W. Schlenker, +10 more
- 16 Nov 2012 - 
TL;DR: The results suggest that kinetics, as opposed to thermodynamics, can dominate recombination via triplet excitons in these blends and that optimization of charge separation and kinetic suppression of charge recombination may be fruitful paths for the next generation of panchromatic organic solar cell materials with high V(OC) and J(SC).
Journal ArticleDOI

High-Efficiency Nonfullerene Organic Solar Cells with a Parallel Tandem Configuration.

Lijian Zuo, +7 more
- 10 Jul 2017 - 
TL;DR: This work stresses the importance of employing a parallel tandem configuration for achieving efficient light harvesting in nonfullerene-based OSCs and provides a useful strategy for exploring the ultimate performance of organic solar cells.
Journal ArticleDOI

Red-emitting electroluminescent devices based on osmium-complexes-doped blend of poly(vinylnaphthalene) and 1,3,4-oxadiazole derivative

Xuezhong Jiang, +3 more
- 15 Oct 2002 - 
TL;DR: In this article, a double-layer light-emitting device using osmium (Os)-complexes-doped blend of poly(vinylnaphthalene) (PVN) and 2-(4-tert-butylphenyl)-5-(4biphenylyl)-1,3,4-oxadiazole (pVN:PBD) as the emitting layer.
Journal ArticleDOI

Pyrene and diketopyrrolopyrrole-based oligomers synthesized via direct arylation for OSC applications.

Shi-Yong Liu, +11 more
- 23 Apr 2014 - 
TL;DR: An atom efficient and facile synthetic strategy for accessing multi-diketopyrrolopyrrole (DPP)-based oligomers used in solution-processed organic field effect transistors (OFETs) and organic solar cells (OSCs) has been developed.
