Impact of the III-V/Ge nucleation routine on the performance of high efficiency multijunction solar cells
Laura Barrutia, Ivan García, Enrique Barrigon +3
This paper addresses the influence of III-V nucleation routines on Ge substrates for the growth of high efficiency multijunction solar cells. Three exemplary nucleation routines wi…
Hot-Carrier Separation in Heterostructure Nanowires observed by Electron-Beam Induced Current
Jonatan Fast, Enrique Barrigon, Mukesh Kumar +7
The separation of hot carriers in semiconductors is of interest for applications such as thermovoltaic photodetection and third-generation photovoltaics. Semiconductor nanowires of…
Three-dimensional imaging of beam-induced biasing of InP/GaInP tunnel diodes
Cristina Cordoba, Xulu Zeng, Daniel Wolf +4
Electron Holographic Tomography was used to obtain 3-dimensional reconstructions of the morphology and electrostatic potential gradient of axial GaInP/InP nanowire tunnel diodes. C…
Combined photo- and electroreflectance of multijunction solar cells enabled by subcell electric coupling
D. Fuertes Marrón, E. Barrigón, M. Ochoa +1
Electric coupling between subcells of a monolithically grown multijunction solar cell in short circuit allows their simultaneous and independent characterization by means of photo-…
InP/InAsP Nanowire-based Spatially Separate Absorption and Multiplication Avalanche Photodetectors
Vishal Jain, Magnus Heurlin, Enrique Barrigon +11
Avalanche photodetectors (APDs) are key components in optical communication systems due to their increased photocurrent gain and short response time as compared to conventional pho…
Application of photoreflectance to advanced multilayer structures for photovoltaics
D. Fuertes Marrón, E. Cánovas, I. Artacho +11
Photoreflectance (PR) is a convenient characterization tool able to reveal optoelectronic properties of semiconductor materials and structures. It is a simple non-destructive and c…
