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 …

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 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. …

In dit artikel ga ik in op de relatie tussen religieuze levensbeschouwing en onze bestaanswerkelijkheid en trek daarbij enkele consequenties voor de psychosociale hulpverlening. De aandacht voor religieuze overtuiging en het belang daarvan voor het daadwerkelijk geleefde leven is de laatste decennia …

Ethiek is een wezenlijk aspect van supervisieprocessen. Dit artikel bespreekt hoe morele vragen in supervisie methodisch bewerkt kunnen worden, op basis van drie vormen van morele positiebepaling. Belangrijk daarbij is het morele referentiekader van de supervisor. Vraag is of de supervisor zich daarvan …

Transitions in health care and the increasing pace at which technological innovations emerge, have led to new professional approach at the crossroads of health care and technology. In order to adequately deal with these transition processes and challenges before future professionals access the labour …

The scope of this investigation is the development and testing of a new type of greenhouse with an integrated linear Fresnel lens, receiver module and an innovative system for tracking to exploiting all direct radiation in a solar energy system. …

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 …

Model calculations and the few data that are available show that over 100 L water condense yearly on each square meter of a greenhouse cover. It is known that the presence of condensate reduces light transmission. This effect is suppressed to some extent by adding film-forming (anti-drop) additives to …
