The objective of this concept is a significant reduction of energy consumption in greenhouses and buildings with large facades and windows by using available solar energy. The scope of this investigation is to study the advantages of a building integrated CPV system. The basic idea is that a larger fraction …

Nederland beschikt over 350 serviceflats, met opgeteld circa 40.000 appartementen5). Ooit vormden ze een breed gewaardeerd alternatief voor wonen in een verzorgingshuis. Op dit ogenblik worden nogal wat complexen met leegstand geconfronteerd. Dat is opmerkelijk: enerzijds neemt het aantal ouderen als …

In this paper the design and development of a new type of greenhouse with an integrated filter for reflecting near infrared radiation (NIR) and a solar energy delivery system is described. Especially the optical parts as the spectral selective film, the properties of the circular reflector and the efficiencies …

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 previous research a new type of greenhouse with an integrated concentrated photovoltaic system (CPV) was developed based on a circular covering geometry and an integrated filter for reflecting the near infrared radiation (NIR) of the greenhouse and exploiting this radiation in a solar energy system. …

Al meer dan dertig jaar is Leren communiceren een veel gebruikt handboek in het hoger onderwijs. Of het nu gaat om communicatieonderwijs in aparte vakken of om vaardighedentraining die is geïntegreerd in projecten, stages en opdrachten, Leren communiceren is de communicatieleidraad bij uitstek. In deze …

In psychiatric care professionals perceive some patients as ‘difficult’, especially patients with long-term non-psychotic disorders. For these patients few evidence-based treatments exist. An intervention program, Interpersonal Community Psychiatric Treatment (ICPT), was developed by the authors. It …

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 new type of greenhouse with linear Fresnel lenses in the cover performing as a concentrated photovoltaic (CPV) system is presented. The CPV system retains all direct solar radiation, while diffuse solar radiation passes through and enters into the greenhouse cultivation system. The removal of all direct …
