TL;DR: In this paper, a GaAs-based top tandem solar cell structure was bonded to an InP-based bottom tandem cell with a difference in lattice constant of 3.7%.
Journal ArticleDOI
Four-Junction Wafer-Bonded Concentrator Solar Cells
Frank Dimroth,T.N.D. Tibbits,M. Niemeyer,Felix Predan,Paul Beutel,Christian Karcher,E. Oliva,Gerald Siefer,David Lackner,Peter Fus-Kailuweit,Andreas Bett,Rainer Krause,Charlotte Drazek,Eric Guiot,Jocelyne Wasselin,Aurélie Tauzin,Thomas Signamarcheix +16 more
TL;DR: In this article, three cell architectures are presented using the same two top junctions of GaInP/GaAs but different infrared absorbers based on Germanium, GaSb, or GaInAs on InP.
Journal ArticleDOI
III–V-on-silicon solar cells reaching 33% photoconversion efficiency in two-terminal configuration
Romain Cariou,Romain Cariou,Jan Benick,Frank Feldmann,Frank Feldmann,Oliver Höhn,Hubert Hauser,Paul Beutel,Nasser Razek,Markus Wimplinger,Benedikt Bläsi,David Lackner,Martin Hermle,Gerald Siefer,Stefan W. Glunz,Stefan W. Glunz,Andreas W. Bett,Frank Dimroth +17 more
TL;DR: Cariou et al. as discussed by the authors used wafer bonding to permanently join a GaInP/GaAs top cell with a silicon bottom cell, achieving a 1-sun AM1.5G conversion efficiency of 33.3%.
Journal ArticleDOI
Monolithic Two-Terminal III–V//Si Triple-Junction Solar Cells With 30.2% Efficiency Under 1-Sun AM1.5g
Romain Cariou,Jan Benick,Paul Beutel,Nasser Razek,Christoph Flötgen,Martin Hermle,David Lackner,Stefan W. Glunz,Andreas W. Bett,Markus Wimplinger,Frank Dimroth +10 more
TL;DR: In this article, a triple-junction GaInP/Al x Ga 1- x As/Si solar cells were fabricated using surface-activated direct wafer bonding, which achieved bulk-like bond strength, high transparency, and conductivity over 4-inch wafer area.
Proceedings ArticleDOI
