Highly efficient and bending durable perovskite solar cells: toward a wearable power source

Byeong Jo Kim, +12 more
- 05 Mar 2015 - 
TL;DR: In this article, a flexible perovskite solar cell exhibiting 12.2% power conversion efficiency (PCE) while using a low-temperature technology for the fabrication of a compact charge collection layer is presented.

Method of forming copper/copper alloy interconnection with reduced electromigration

Takeshi Nogami, +2 more
TL;DR: In this paper, the seed layer is annealed at about 100°C to about 400°C. to increase the grain size of the seed layers and impart a (111)-dominant crystallographic option before plating the Cu or Cu alloy interconnections thereon the seed-layer.
Journal ArticleDOI

A Strain-Insensitive Stretchable Electronic Conductor: PEDOT:PSS/Acrylamide Organogels

Yoo-Yong Lee, +6 more
- 01 Feb 2016 - 
TL;DR: UNLABELLED Organogel-based stretchable electronic conductors exhibit electrical conduction even under a large stretching deformation of 300% without electrochemical reactions at DC voltages.
Journal ArticleDOI

Measurement of stresses in Cu and Si around through-silicon via by synchrotron X-ray microdiffraction for 3-dimensional integrated circuits

Arief Suriadi Budiman, +10 more
- 01 Mar 2012 - 
TL;DR: Through-silicon via (TSV) has been used for 3-dimentional integrated circuits and results suggest that Cu stress may lead to reliability as well as integration issues, while Si stress might lead to device performance concerns.
Journal ArticleDOI

A new hematite photoanode doping strategy for solar water splitting: oxygen vacancy generation.

Tae-Youl Yang, +7 more
- 16 Jan 2013 - 
TL;DR: The controlled generation of oxygen vacancies can activate the photoactivity of pure hematite remarkably and further enhance the Sn doping effects synergistically and results in the optimum concentration region to show the high photocurrent and low onset voltage.
