PRINTED METALLISATION OF PHOSPHORUS DOPED SILICON SURFACES FOR SOLAR CELL APPLICATIONS
… solar cells. Metallisation of phosphorus doped surfaces using screen-printed silver (Ag) pastes is a well-established process. However, its performance is limited by several fundamental factors. Its inability to reliably print fine metal lines on the front surface of the solar cell results in …

Functional Materials and Device Concepts for Magnetic Sensing, Gas Detection and Energy Harvesting
… interact with target gases. Nanostructuring, surface doping, and polymer functionalization are investigated to enhance sensitivity, selectivity, and humidity resistance. Particular emphasis is placed on tailoring surface interactions and optimizing responses to gases relevant to environmental …

Visible and Infrared Light Detection Using 2D Materials
… voltage due to antireflection coating effects, surface doping, and surface trap passivation. A single absorber solar cell with an open circuit voltage (Voc) of 380 mV and short circuit current density (Jsc) of 10.7 mA/cm² was demonstrated, thanks to the absorber coating. Shifting focus to …

PEM-fuel cell catalysts from nanoscopic precursors : a comparative study
… of W-doped Pt- and Co-doped Pt/Ru catalysts "Surface doping" was applied as a method for tuning fuel cell catalysts. It was found that W(0) doping on the Pt/Vulcan catalysts in small amounts activates the catalysts shifting the onset potentials in potentio-dynamic CO-oxidation studies. 1 wt.% …

High throughput methods for synthesis and impedance characterisation of ABO3 gas sensing materials
… allowed mixing on the molecular level and bulk doping of the materials during the preparation. Nanoscaled compounds that crystallised after temperature treatment were achieved. The prepared ABO3 materials offered various properties and possibilities for gas sensing materials, especially for high …

First-principles study of doped hematite surfaces for photoelectrochemical water splitting
… way to improve the PEC activity of α-Fe2O3 is by doping with other elements. In particular, surface doping is proved to be more beneficial than bulk doping because it reduces the distance moved by the charge carriers from inside the bulk to the surface where they are required for interfacial …
