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...

Purpose: This study evaluates the potential of biomass ash as raw clinker material and the influence of biomass feedstock and thermal conversion technology on biomass ash properties. Methods: A set of criteria for biomass feedstock and ash properties (i.e. CaO/SiO2 ratio and burnability) are established. A large dataset was collected and the...

Sputtered transparent conducting oxides (TCOs) are widely accepted transparent electrodes for several types of high-efficiency solar cells. However, the different sputtering yield of atoms makes stoichiometric transfer of target material challenging for multi-compounds. Additionally, the high kinetic energies of the arriving species may damage...

As the semiconductor industry progresses toward more complex multilayered devices with ever smaller features, accurately aligning these layers with respect to each other has become a bottleneck in the advancement to smaller transistor nodes. To avoid alignment issues, area-selective atomic layer deposition (ALD) can be employed to deposit...

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...

The surface of wind turbine blades are prone to degradation due to exposure to the elements. Rain, hail, insects are among the many causes of turbine blade degradation or erosion. Surface degradation of the wind turbine blades leads to a reduction in the aerodynamic performance, resulting in power losses. The effect of surface degradation is...

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...
