A miniaturized planar Yagi-Uda antenna for integration with PicoSats or other SmallSat missions is proposed. Miniaturization techniques, such as meandering and 1-D artificial dielectric concepts to reduce the guided wavelength, are employed to overcome space constraints imposed by the SmallSat footprint while still maintaining good performance...

System voltages can cause significant degradation in photovoltaic modules. Polarization-type potential-induced degradation (PID) is accompanied by decreases in the short-circuit current density and the open-circuit voltage. The system voltage causes a polarization and surface charge accumulation, increasing the interface recombination. The...

Grootschalige toepassing van zonnecellen (photovoltaic cells, PV) in de gebouwde omgeving is gelimiteerd, mede omdat dakoppervlakken niet volledig benut kunnen worden ten gevolge van de ligging en de aanwezigheid van verstorende elementen als schoorstenen, dakkapellen, daklichten, etc. Het wegennet in Nederland biedt aanknopingspunten voor...

Capacitive touchscreens are increasingly widespread, featuring in mobile phones and tablets, as well as everyday objects such as cars and home appliances. As a result, the interfaces are uniquely placed to provide a means of communication in the era of the Internet of Everything. Here, we show that commercial touchscreens can be used as reader...

PV deployment growth is an unmatched success story in the energy sector over recent years. However, European PV manufacturers are facing a decline in production due to competition from third countries. The fragmentation of the value chain is believed to be one of the major factor for this decrease in the competitiveness. SUPER PV is a...

Back end interconnection technology is presented for CIGS using laser scribing and inkjet printing of dielectric material. Shunt-free laser scribing of CIGS is shown, which is essential in the back end approach for monolithic serial interconnection. Full back end interconnected mini-modules of 20x20cm2 were made and show no electrical losses...

In this paper we show the results from indoor and outdoor measurements on solar cells and modules, manufactured with different bifacial and monofacial cell architectures and encapsulated in different configurations. Reflection/transmission, IV and IQE spectra of single-cell laminates were measured and used to determine the energy spectra for all...

A record low surface recombination current for boron doped p+poly-Si passivation on random pyramid textured Cz wafers(Jo,s of 10 fA/cm2) has been achieved, with an outlook to even lower Jo,s values. Solar cells have been completed using a lowcost process flow based on screen-printed and firing-through metallization and with a process flow that...

Silicon is the most studied semiconductor, having almost every aspect of it being investigated. All this information is spread over a large set of publications, review articles and textbooks and cannot be found in a single location. Furthermore, the available data is not always consistent and depends on the techniques and samples used. This...

The installation of measurements in distribution grids enables the development of data driven methods for the power system. However, these methods have to be validated in order to understand the limitations and capabilities for their use. This paper presents a systematic validation of a neural network approach for voltage estimation in active...

We report on the degradation of organic photovoltaic (OPV) cells in both indoor and outdoor environments. Eight different research groups contributed state of the art OPV cells to be studied at Pomona College. Power conversion efficiency and fill factor were determined from IV curves collected at regular intervals over six to eight months....

Intrinsic light stability of transparent MoO3/Ag/TiO2 electrode is studied in four different polymer:fullerene solar cell configurations. We demonstrate that this stack can successfully replace ITO both in superstrate and substrate configurations required for non-transparent carriers. Although we observe that exposure of thin Ag layer directly...

In applications such as organic light emitting diodes (OLEDs) or photovoltaic cells a homogenous voltage distribution in the large anode layer needs to be ensured by including a metal grid with a transparent conductor layer. To ensure sufficient conductivity, relatively thick metal lines are used, which increases the risk of electrical shorts...

Optimal front electrode design is one of the approaches to improve the performance of solar cells. This work introduces the application of topology optimization (TO) to design complex front metallization patterns for solar cells. TO optimizes the distribution of electrode material on the front surface of the solar cell, such that its power...

For its application as transparent conductor in light-emitting diodes and photovoltaic cells, both the in-plane and out-of-plane conductivity of PEDOT:PSS are important. However, studies into the conductivity of PEDOT:PSS rarely address the out-of-plane conductivity and those that do, report widely varying results. Here a systematic study of the...

At present, transparent conducting oxides (TCOs) are still superior in performance to most other transparent conductors. Results on opto-electronic modeling and design optimization of TCOs are presented using a monolithically integrated CIGS cell configuration as case. For various cell dimensions and TCO characteristics, the cell output was...

The effect of the molecular weight of poly[9,9-didecanefluorene-alt-(bis-thienylene) benzothiadiazole] (PF10TBT) on the photovoltaic performance of fullerene-based bulk heterojunction solar cells is investigated. An increase in molecular weight of two orders of magnitude results in a 30% increase of the short-circuit current and a rise of the...

Here, the performance of bulk-heterojunction solar cells based on a series of bisadduct analogues of commonly used derivatives of C60 and C 70, such PCBMs and theirthienyl versions, is investigated. Dueto their higher lowest unoccupied molecular orbital an increase in open-circuit voltage and thus performance is expected. It is shown that the...

The introduction in the market of ubiquitous sensing applications relies heavily on the availability of affordable sensors. Key in the cost of a sensor is its modus of manufacture. In this paper a sensing scheme is presented, in which the signal transduction is based on an induced change in the optical path between an organic light emitting...
