Structural and optical changes induced by incorporation of antimony into InAs/GaAs(001) quantum dots
A. G. Taboada, A. M. Sánchez, A. M. Beltrán +12
We present experimental evidence of Sb incorporation inside InAs/GaA(001) quantum dots exposed to an antimony flux immediately before capping with GaAs. The Sb composition profile…
Contribution to the study of sub-bandgap photon absorption in quantum dot InAs/AlGaAs intermediate band solar cells
Juan Villa, Iñigo Ramiro, José María Ripalda +4
Intermediate band solar cells (IBSCs) pursue the increase in efficiency by absorbing below-bandgap energy photons while preserving the output voltage. Experimental IBSCs based on q…
Engineering the reciprocal space for ultrathin GaAs solar cells
Jeronimo Buencuerpo, Jose M. Llorens, Jose M. Ripalda +2
III-V solar cells dominate the high efficiency charts, but with significantly higher cost than other solar cells. Ultrathin III-V solar cells can exhibit lower production costs and…
Impact of spectral effects on photovoltaic energy production: A case study in the United States
José M. Ripalda, Daniel Chemisana, José M. Llorens +1
The time averaged efficiency of photovoltaic modules in the field is generally lower than the efficiency measured in the laboratory under standard testing conditions due to the com…
Strain balanced quantum posts
D. Alonso-Álvarez, B. Alén, J. M. Ripalda +8
Quantum posts are assembled by epitaxial growth of closely spaced quantum dot layers, modulating the composition of a semiconductor alloy, typically InGaAs. In contrast with most s…
In-situ accumulated stress measurements: application to strain balanced quantum dots and quantum posts
D. Alonso-Álvarez., B. Alén, J. M. Ripalda +6
In this work we use the in-situ accumulated stress monitoring technique to evaluate the evolution of the stress during the strain balancing of InAs/GaAs quantum dots and quantum po…
