Journal ArticleDOI
Scalable fabrication of efficient organolead trihalide perovskite solar cells with doctor-bladed active layers
TL;DR: In this article, a simple, high throughput and low-cost doctor-blade coating process was used for the fabrication of perovskite solar cell panels, which can be compatible with the roll-to-roll fabrication process.
Journal ArticleDOI
Influence of Copper Oxide on Femtosecond Laser Surface Processed Copper Pool Boiling Heat Transfer Surfaces
Corey Kruse,Alfred Tsubaki,Craig Zuhlke,Dennis R. Alexander,Mark R. Anderson,Edwin Peng,Jeffrey E. Shield,Sidy Ndao,George Gogos +8 more
TL;DR: In this article, an oxide layer was observed and measured with the use of a focused ion beam milling process and found to have thickness of a few microns, which was found to be related to the laser fluence parameter.
Journal ArticleDOI
Micro/nanostructures formation by femtosecond laser surface processing on amorphous and polycrystalline Ni60Nb40
Edwin Peng,Alfred Tsubaki,Craig Zuhlke,Meiyu Wang,Ryan J. Bell,Michael J. Lucis,Troy Anderson,Dennis R. Alexander,George Gogos,Jeffrey E. Shield +9 more
TL;DR: In this paper, two unique classes of surface structures, below surface growth (BSG) and above surface growth mounds, were formed by femtosecond laser surface processing on amorphous and polycrystalline Ni60Nb40 with two different grain sizes.
Journal ArticleDOI
Experimental explanation of the formation mechanism of surface mound-structures by femtosecond laser on polycrystalline Ni60Nb40
Edwin Peng,Alfred Tsubaki,Craig Zuhlke,Meiyu Wang,Ryan J. Bell,Michael J. Lucis,Troy Anderson,Dennis R. Alexander,George Gogos,Jeffrey E. Shield +9 more
TL;DR: There is a clear difference in the formation mechanisms of ASG- and BSG-mounds during FLSP, indicating preferential valley ablation as the primary formation mechanism.
Journal ArticleDOI
Growth mechanisms of multiscale, mound-like surface structures on titanium by femtosecond laser processing
Edwin Peng,Ryan J. Bell,Craig Zuhlke,Meiyu Wang,Dennis R. Alexander,George Gogos,Jeffrey E. Shield +6 more
TL;DR: The subsurface microstructure of a series of mound-like FLSP structures formed on commercially pure titanium using five combinations of laser fluence and cumulative pulse counts was studied, showing evidence that preferential laser ablation is the primary formation mechanism.
