(author)Single junction crystalline silicon (c-Si) solar cells are reaching their practical efficiency limit whereas perovskite/c-Si tandem solar cells have achieved efficiencies above the theoretical limit of single junction c-Si solar cells. Next to low-thermal budget silicon heterojunction architecture, high-thermal budget carrier-selective...article 2023

Kahrobaei, S. (author), Farajzadeh, R. (author)A potential solution to mitigate the adverse effects of viscous fingering, gravity override, and reservoir heterogeneity on the efficiency of gas injection in porous media is to inject the gas with a solution containing surface-active agents such as surfactants or nanoparticles. The efficiency of these processes largely depends on the generation...article 2019

(author)A novel back-contacted solar cell based on a submicron copper indium gallium (di)selenide (CIGS) absorber is proposed and optically investigated. First, charge carrier collection feasibility is studied by band diagram analysis. Then, two back-contacted configurations are suggested and optimized for maximum current production. The results are...article 2019

(author)Multi-junction solar cells are considered for various applications, as they tackle various loss mechanisms for single junction solar cells. These losses include thermalization and non-absorption below the band gap.

van Deelen, J. (author), Tezsevin, Y. (author), Barink, M. (author)Most research of texturization of solar cells has been devoted to Si based cells. For perovskites, it was assumed that texturization would not have much of an impact because of the relatively low refractive indexes lead to relatively low reflection as compared to the Si based cells. However, our optical modeling shows that a significant gain in...article 2017

van Deelen, J. (author)For a wide range of bandgaps of solar cell materials, the potential contribution of upconversion materials was calculated and related to various configurations of the solar cell and upconversion layers. Moreover, by comparing these various strategies with the potential of a dual junction tandem cell configuration, a compelling case is made for...article 2017

(author)Background: Wholegrain foods are known to be health-beneficial but their sensory characteristics may be a limiting factor for consumption. The scientific literature of factors influencing sensory quality of wholegrain foods is rather scarce. Scope and approach: Many cereals like rye, oats, barley and sorghum are actually used mainly as...article 2016

(author)To control tactile friction, that is the friction between fingertip and counter-body, the role of surface texture is required to be unveiled and defined. In this research, an experimental approach is used based on measuring tactile friction for directional texture (grooved channel) with varying depths. For a reference surface, in this current...article 2015

One can obtain a wide range of structures using mixtures of different structuring ingredients such as for example protein mixtures. Mixed soy protein isolate (SPI)/gelatine gels were analyzed for their linear rheological properties, fracture...article 2015

(author)The main obstacle to calculate the 'feel' of a product from its surface properties is the ill-defined surface topography that is encountered after the most surface finishing processes. In this work this obstacle was avoided by producing well-defined surface topographies by laser texturing. The friction of textures having surface features with...article 2012

Hogenkamp, P.S. (author), Mars, M. (author), Stafleu, A. (author), de Graaf, C. (author)Food intake and a food’s expected satiating effect initially rely on sensory attributes. People will learn about the food’s satiating capacity by exposure. We investigated whether repeated consumption changed the expected satiety effects and intake of iso-energetic liquid and semi-solid foods. In a randomised cross-over study, participants (n =...article 2012
