Light-induced performance increase of silicon heterojunction solar cells
(2016)Silicon heterojunction solar cells consist of crystalline silicon (c-Si) wafers coated with doped/intrinsic hydrogenated amorphous silicon (a-Si:H) bilayers for passivating-contact formation. Here, we unambiguously demonstrate ... -
Lightsafe: An interactive Security Technology for Banknotes and ID Documents
(2022-04-12)We present a novel class of interactive security features . Based on light guiding in thin foils, the features are verified by illuminating them with a white light source, such as the LED of a smartphone, and viewing ... -
Linear Parameter-Varying Kalman Filter for angular velocity estimation of a reaction sphere actuator for satellite attitude control
(2017)This paper presents a novel angular velocity estimation strategy of a Reaction Sphere (RS) for satellite attitude control based on a Linear Parameter-Varying (LPV) Kalman Filter. The reaction sphere is a permanent magnet ... -
Liquid Metal Based Antenna for Wearable Electronic
(2016-09-05)In this paper, a liquid metal based antenna for wearable applications is presented. The proposed solution can be used as the basis for flexible and stretchable antennas. The concept has been prototyped in a loop antenna, ... -
Load shifting for tertiary control power provision
(2015-05)The objective of this work is load shifting of domestic appliances for tertiary reserve provision. Aggregate load curve simulators are built by modelling stochastic consumer behaviour. Analysis is then performed on the ... -
Long-term medical survey system
(2008-08-17)The European Space Agency (ESA) commissioned CSEM to design, build, validate and deliver one fully operational ground prototype of a system (LTMS2) measuring physiological parameters. The system was shipped and will be ... -
