The selenisation of Cu-Ga-In metallic precursors is investigated by in-situ X-Ray Diffraction (XRD) in a selenisation tool which mimics at the laboratory scale an industrial tool (thus fully scalable) and allows fine control over the selenisation parameters and reproducibility. In this setup, the interdiffusion of Ga and In was significantly...

A custom-made, highly versatile and industrially-relevant selenisation furnace with in situ XRD capabilities is presented. Mimicking an RD scale furnace used in our baseline at TNO/Solliance, it uses only elemental chalcogens and gives control over a wide set of process parameters not accessible in commercial setups. It additionally allows fast...

In order to control the bandgap profile of CIGSe absorbers, several key parameters of the absorber formation process have been investigated using semi-industrial 30×30 cm2 chalcogenization equipment. It was found that the degree of gallium-indium interdiffusion depends on the thermal budget of the process and on the selenium vapor pressure at...

Carbon nanotube assemblies can be used for specific applications such as sensors and filters. We present a method and proof-of-concept to directly grow vertically-aligned carbon nanotube structures within sealed enclosures by means of a feedback-controlled laser-assisted chemical vapor deposition technique. The process is compatible with a...

The evolution of turbulent jet diffusion flames of natural gas in air is predicted using a finite-volume procedure for solving the flow equations. The model is three dimensional, elliptic and based on the conserved-scalar approach and the laminar flamelet concept. A laminar flamelet prescription for temperature, which is in agreement with...
