We present a novel method to achieve light trapping in thin film silicon solar cells. Unlike the commonly used surface textures, such as Asahi U-type TCO, that rely on light scattering phenomena, we employ embossed periodically arranged micro-pyramidal structures with feature sizes much larger than the …

A greenhouse with Fresnel lenses in the south facing roof and a receiver for concentrated Photovoltaics with water cooling (CPVT system) will result in electrical and thermal energy output from the solar energy excess entering a greenhouse. The PV system converts about half of the direct radiation into …

In this study, we present a new light absorption enhancement method for p-i-n thin film silicon solar cells using pyramidal surface structures, larger than the wavelength of visible light. Calculations show a maximum possible current enhancement of 45% compared with cells on a flat substrate. We deposited …

In Dutch universities, honors programs are a fast growing development. The first such programs started in 1993. Twenty years later a large number of programs are implemented at nearly all research universities and also at many universities of applied sciences in the Netherlands. Recent data have revealed …

Untrained listeners demonstrate implicit knowledge of syntactic patterns and principles. Untrained generative music ability, for example singing, humming, and whistling, is a largely unconscious or intuitive application of these patterns and principles. From the viewpoint of embodied cognition, listening …

Damping constitutes a major source of uncertainty in dynamic analysis and an open issue to experimental and analytical research. After a thorough review of the current views and approaches existing in literature on damping and its appropriate modelling, this paper focuses on the implications of the available …

The purpose of this study was to investigate the influence of body function, activities and pain on the level of activity in adults with Kashin Beck Disease (KBD). Seventy-five KBD patients with a mean age of 54.8 years (SD 11.3) participated. Anthropometrics, range of joint motion (ROM) and muscle strength …

Land use or land-use changes can trigger or generate hazards and affect the potential consequences of these hazards. Deforestation can trigger land slides, for example, and land reclamation or levee construction can increase flood hazards downstream. New dwellings in or near forests can trigger wildfires, …

In deze scriptie is er antwoord gegeven op de vraag: Wat is de waarde van Pesso (basisbehoeften, basisstand, structures) bij het geven van PMT binnen een schemagerichte groep vrouwen tussen de 29 en 46 jaar met een Borderline persoonlijkheidsstoornis? Schematherapie is een therapie die voortborduurt …

In dit rapport wordt onderzocht wat de bijdrage van houtstructuren is voor ecologisch herstel van de visstand in de Overijsselse Vecht. Er zijn 2 soorten houtstructuren te onderscheiden: beddingstructuren en oeverstructuren. Beddingstructuren worden in de watergang aangelegd, terwijl oeverstructuren …
