Plonasluoksnių saulės elementų apdirbimas ultratrumpais lazerių impulsais /
… analysis of thin layer ultrashort pulsed laser ablation processes for photovoltaic devices. Experimental work was supported by modeling and simulation of energy coupling and dissipation inside the layers. The absorbed laser energy was transformed to localized transient heating inside the …

The Role of residual stresses in ceramic substrate materials for hybrid thick film applications
… back of the substrate, particularly during the laser scribing phase of the finished device. Significant tensile stresses were also observed in the Silver-Palladium (Ag-Pd) metallization. TDR measurements indicated significant response variations which were attributed to these induced stresses. …

Genesis : the search for origins : the curation and contamination control of returned solar wind samples
… to aid development of a set of protocols for the laser scribing and subdivision of the Genesis silicon collector array materials. Optimisation of the scribing speed and the positioning of the focal point of the laser were carried out. It was found that scribe width was independent of both factors. …

Ultra-thin transparent electrodes for energy applications
… in thin film photovoltaic technology: laser scribing. AZO/Ag/AZO multilayers must be able to guarantee the same level of TCO reliability under laser scribing processes. In this study, we used a single nanosecond laser pulse to irradiate AZO/Ag/AZO deposited on glass.

A Rapid and Power-Efficient Laser-Induced Graphene Micro-Thermocycler for DNA Polymerase Chain Reaction
… testing. This research aims to develop a laser induced graphene (LIG) heater as the heating element for PCR point-of-care testing (POCT), as the PCR detection result is highly dependent on following a specific reagent heating cycle. In particular, the LIG heater can be integrated directly …
