Characterization of NLO crystal absorption for wavelengths 1w to 4w

An overview is presented of the characteristic features for the sandwich concept used for NLO crystal bulk absorption measurements. The sandwich concept is a photo-thermal absorption measurement concept...

Evaluation of light trapping structures for liquid-phase crystallized silicon on glass (LPCSG)

Liquid-phase crystallized silicon on glass (LPCSG) presents a promising material to fabricate high quality silicon thin films, e.g. for solar cells and modules. Using continuous wave line focus laser irradiation...

Viscous behavior of synthetic silica glass tubes during collapsing

The viscous behavior of synthetic silica tubes is studied during collapsing. This technique can be applied directly during the modified chemical vapor deposition (MCVD) of light-guiding preform preparation....

Aqueous photocurrent measurements correlated to ultrafast electron transfer dynamics at ruthenium tris diimine-sensitized NiO photocathodes

Understanding the structural and electronic factors governing the efficiency of dye-sensitized NiO photocathodes is essential to optimize solar fuel production in photo electrochemical cells (PECs). For...

Temperature and hydrogen diffusion length in hydrogenated amorphous silicon films on glass during scanning with a continuous wave laser at 532 nm wavelength

Annealing of hydrogenated amorphous silicon (a-Si:H) films by laser scanning is of interest for (e.g.) defect reduction. For reproducible laser treatment, knowledge about temperature and hydrogen diffusion...
