Luxembourg, S.L. (author), Polman, A. (author), Neder, V. (author), Energieonderzoek Centrum Nederland (author)Green colored photovoltaic modules based on silicon heterojunction solar cells integrated with periodic arrays of light scattering Si nanoscatterers were made. Here, we expand this concept to multiple colors and color combinations. We show that random arrays of silicon nanoarrays can be combined to pixels to create the desired color. By...conference paper 2017

Luxembourg, S.L. (author), Polman, A. (author), Neder, V. (author)We demonstrate photovoltaic modules with a bright green color based on silicon heterojunction solar cells integrated with arrays of light scattering dielectric nanoscatterers. Dense arrays of crystalline silicon nanocylinders, 100-120 nm wide, 240 nm tall, 325 nm pitch, are made onto module cover slides using substrate-conformal soft-imprint...article 2017

Sinke, W.C. (author), Polman, A. (author), Knight, M.W. (author), Garnett, E.C. (author), Ehrler, B. (author)Recent developments in photovoltaic materials have led to continual improvements in their efficiency. We review the electrical characteristics of 16 widely studied geometries of photovoltaic materials with efficiencies of 10 to 29%. Comparison of these characteristics to the fundamental limits based on the Shockley-Queisser detailed-balance...article 2016

Polman, A. (author), Newman, B.K. (author), Kosten, E.D. (author), Lloyd, J.V. (author), Atwater, H.A. (author)Restricting the light escape angle within a solar cell significantly enhances light trapping, resulting in potentially higher efficiency in thinner cells. Using an improved detailed balance model for silicon and neglecting diffuse light, we calculate an efficiency gain of 3%abs for an ideal Si cell of 3-µm thickness and the escape angle...article 2015

Weeber, A.W. (author), Lenzmann, F.O. (author), Polman, A. (author), Spinelli, P. (author)Dielectric nanoparticle arrays have been proposed as antireflection coatings and light-trapping schemes for thin-film c- Si solar cells. However, practical aspects about the integration of these nanostructures with solar modules have yet to be investigated. In this paper, we study the effect of ethylene vinyl acetate (EVA) encapsulation on the...article 2015

(author), Salpakari, J. (author)A series of (n-i-p) a-Si:H solar cells with light-trapping by front-side plasmonic Ag nonoparticle arrays was compared to a reference without the plasmonic arrays as well as to a benchmark with a conventional textured back-side reflector for light-trapping. The external quantum efficiency of the solar cells was determined experimentally by...article 2013

Lenzmann, F.O. (author), Polman, A. (author), van Lare, M. (author), Verschuuren, M.A. (author)We demonstrate effective mode coupling by light scattering from periodic Ag nanoparticle arrays printed onto a completed thin-film a-Si:H solar cell. Current-voltage measurements show a photocurrent enhancement of 10% compared to a flat reference cell with a standard antireflection coating. External quantum efficiency measurements for the...article 2012

Sinke, W.C. (author), Polman, A. (author)De aarde ontvangt per uur meer energie van de zon dan wij met de hele wereldbevolking per jaar nodig hebben. Zonnestroom is daarom een bron van duurzame energie met een enorm potentieel. De afgelopen tijd is de sector in een stroomversnelling geraakt, met een gemiddelde jaarlijkse groei van ongeveer 40 procent. Maar er zit nog meer aan te komen....other 2010

Gezondheidsorganisatie TNO Nederlands Instituut voor Praeventieve Gezondheidszorg TNO (author), Polman, A. (author)De veroudering van een bevolking is een uitermate samengesteld gebeuren, waarvan de factoren, die van invloed zijn, voor een deel gevonden worden in het verleden. De daling van de sterfte in de jongste leeftijdsklassen, die reeds in de tweede helft van de vorige eeuw intrad, is één dezer factoren. Naarmate de exogene factoren, die de gezondheid...article 1954
