Current road lighting systems are outdated and should be replaced with systems which can sense their environment and even weather changes, i.e. users that are passing with consumer electronic devices such as mobile phones. Systems such as these should then react intelligently. In this way these future …

Business landscapes are changing at global, regional and sectoral levels as well as the social and ecological contexts. In order to understand what these changes are and how clusters are dealing with these, the research explores drivers of change and cluster dynamics using a Complex Adaptive Systems …

The research explores energy clusters and their adaptations to drivers of changes using a Complex Adaptive Systems (CAS) approach. CAS offers a descriptive analytical framework that helps generate insights into drivers of change and cluster developments. The pilot EnTranCE, a living lab cluster, in Energy …

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 …

Storing large amounts of data in an efficient way from the point of view of very fast retrieval is animportant requirement for many industries like KEMA, a company offering consulting, testing andcertification in the energy business. Because their relational database could not cope fast enough with thelarge …

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 …

The objective of an energy management strategy for fuel cell hybrid propulsion systems is to minimize the fuel needed to provide the required power demand. This minimization is defined as an optimization problem. Methods such as dynamic programming numerically solve this optimization problem. Strategies …

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 …
