A round robin test was carried out in four PV laboratories to compare accelerated lifetime testing. Twenty commercial non-packaged CIGS solar cells of similar performance were spread and exposed to damp heat con-ditions (85 ◦C and 85% RH) for approximately 500 h. Their JV performance was monitored during the damp heat exposure. After the test,...

The aberrations of reflective optical systems with one plane of symmetry are investigated in the most general case, with freeform surfaces and possibly different locations of the tangential and sagittal object and image. In this first paper in a series of two, we establish generalized ray-tracing equations including transverse aberrations up to...

The aberrations of reflective optical systems with planar symmetry are investigated in the most general case, with freeform surfaces and possibly different locations of the tangential and sagittal object and image. In this second and last paper, closed-form expressions are derived for the aberrations created by an individual mirror. We study two...

Over een aantal jaar moet op bijna 3 km hoogte, op een bergtop in Chili, ’s werelds grootste telescoop verrijzen. Deze Extremely Large Telescope (ELT) wordt gebouwd door de Europese Zuidelijke Sterrenwacht (ESO). De onderdelen worden momenteel op allerlei plekken ter wereld in elkaar gesleuteld, waaronder in Nederland. Zo zal TNO samen met het...

When controlled in an open-loop fashion, both stationary and dynamical diesel engine performance can deteriorate due to disturbances. Although cycle-to-cycle fuel injection control has the potential of reducing the performance degradation by manipulating the fueling profile in real time, this potential has not been thoroughly studied. This is...

The maritime industry has set clear objectives towards reducing greenhouse gas emissions in the coming decades. Ship based carbon capture (SBCC) could play a large role in reducing these emissions on the short term. This study gives an update on the work that has been conducted towards carbon capture and storage on LNG fuelled vessels. This is...

Quantum computers (QC) promise to solve certain computational problems exponentially faster than a classical computer due to the superposition and entanglement properties of quantum bits (qubits). Among several qubit technologies, spin qubits are a promising candidate for large-scale QC, since (1) they have a small footprint allowing them to be...

In this paper, we report the effect of optical trapping on the enhancement factor for Raman spectroscopy, using a dielectric metasurface. It was found that a higher enhancement factor (up to 275%) can be obtained in a substrate immersed in water, where particles are freee to move, compared to a dried substrate, where the particles (radius r = 9...

Here, we present a pseudo-CMOS NOR gate array based on dual-gate amorphous indium-gallium-zinc oxide thin-film transistors (TFTs) on plastic. We fabricated a 14 × 12 array of NOR gates which was programmed using laser-induced forward transfer printing technology to realize a negative-edge-triggered D flip-flop. Two drive transistors in a...

Dimethyl ether (DME) is one of the most attractive alternative fuel solutions under consideration worldwide. However, its production from CO2-rich feedstock or CO2 directly is limited via conventional processes and therefore considered unattractive. For CO2 utilisation, the production and efficient handling of steam remains a major bottleneck....

Multilayer cantilever beams are used in the measurement of near-field radiative heat transfer. The materials and dimensions of the cantilever probe are chosen in order to improve system performance in terms of sensitivity and noise. This is done using an analytical model that describes the thermo-mechanical and mechanical behavior of the...

Several pathways for potentially greenhouse gas neutral production of ammonia have been investigated compared to today's conventional ammonia production at chemical sites in Antwerp, Dormagen, and Geleen. These pathways include on-site water electrolysis using grid electricity, off-site production via water electrolysis using renewable...

We have developed an SI-traceable narrow-band tunable radiance source based on an optical parametric oscillator (OPO) and an integrating sphere for the calibration of spectroradiometers. The source is calibrated with a reference detector over the ultraviolet/visible spectral range with an uncertainty of < 1%. As a case study, a CubeSat spectro...

Control of optical fields at the nanoscale holds the promise of fast, efficient imaging methods, but is elusive due to the diffraction limit. This paper investigates how a single metasurface patch in the near field of a sample plane may be used to create a wide variety of intensity patterns by applying different illumination profiles from the...

Using Infrastructure-to-Vehicle (I2V) information can be of great benefit when driving autonomously in highdensity traffic situations with limited visibility, since the sensing capabilities of the vehicle are enhanced by external sensors. In this research, a method is introduced to increase the vehicle’s self-awareness in intersections for one...
