Reduced Surface Recombination in Extended-Perimeter LEDs toward Electroluminescent Cooling Open

Luc M. van der Krabben, Natasha Gruginskie, Maarten van Eerden, Jasper van Gastel, P. Mulder , et al. · 2024

III-V semiconductor light-emitting diodes (LEDs) are a promising candidate for demonstrating electroluminescent cooling. However, exceptionally high internal quantum efficiency designs are paramount to achieving this goal. A significant lo…

Improvements in ultra‐light and flexible epitaxial lift‐off GaInP/GaAs/GaInAs solar cells for space applications Open

Jonas Schön, G.M.M.W. Bissels, P. Mulder, Rosalinda H. van Leest, Natasha Gruginskie , et al. · 2022

A thin, lightweight, flexible solar cell is developed that maximizes the power‐to‐mass ratio under AM0 illumination and has a competitive efficiency after typical high energy electron irradiation. The inverted metamorphic triple junction (…

Proton irradiation induced GaAs solar cell performance degradation simulations using a physics-based model Open

A facile light‐trapping approach for ultrathin GaAs solar cells using wet chemical etching Open

Maarten van Eerden, G.J. Bauhuis, P. Mulder, Natasha Gruginskie, Marco Passoni , et al. · 2019

Thinning down the absorber layer of GaAs solar cells can reduce their cost and improve their radiation hardness, which is important for space applications. However, the lighttrapping schemes necessary to achieve high absorptance in these c…

Photon Recycling in Thin-Film GaAs Solar Cells Open

Natasha Gruginskie, G.J. Bauhuis, P. Mulder, Elias Vlieg, J.J. Schermer · 2019

The highest efficiencies in a single-junction solar cells are obtained with devices based on GaAs. As this material is reaching the limit in material quality, the optimization of the design of the cell becomes more important. In this study…
