TL;DR: In this article, a newly developed methodology has been employed in order to make an objectivized assessment of the relevant laser surface treatment technologies, and contextual matrices and roadmaps and technology information sheets allowing for the mainly qualitative comparisons of individual technologies according to harmonized criteria were created as a result of employing the methodology.
Abstract: Several examples have been chosen for presentation from a broad array of laser surface treatment technologies currently researched into and used in industry and the examples are distinguished by their extensive possibilities of future and current applications, especially in the tooling, automotive, and power industry. A newly developed methodology has been employed in order to make an objectivized assessment of the relevant laser surface treatment technologies. Contextual matrices and roadmaps and technology information sheets allowing for the mainly qualitative comparisons of the individual technologies according to harmonized criteria were created as a result of employing the methodology.

TL;DR: In this article, the influence of carbon nanotubes on the properties of dye-sensitised solar cells was examined, and it was shown that the application of carbon-notubes as one of electrodes in a dye-Sensitized solar cell is significantly improving the effectiveness of the solar cell being manufactured.
Abstract: Purpose: The purpose of the work is to examine the influence of carbon nanotubes on the properties of dye-sensitised solar cells. Design/methodology/approach: The research material consisted of samples of glass plates with a conductive layer of FTO onto which layers were subsequently deposited of TiO2 titanium dioxide and titanium dioxide with an absorbed dye, a high conductivity PEDOT:PSS polymer with multi-walled carbon nanotubes, carbon black and graphite. Findings: The application of carbon nanotubes as one of electrodes in a dye-sensitised solar cell is significantly improving the effectiveness of the dye-sensitised solar cell being manufactured. Research limitations/implications: Carbon nanotubes are a good potential material for optoelectronics and photovoltaics. Practical implications: Carbon nanotube electrodes feature high conductivity and high visible light transmission. Originality/value: It is possible to change a structure of a dye-sensitised solar cell by replacing the commonly used platinum in a counter electrode with another electrode permeable for visible light made of a high conductivity PEDOT:PSS polymer with multi-walled carbon nanotubes.
