A Chirality-Based Quantum Leap
Clarice D. Aiello, Muneer Abbas, John M. Abendroth +41
Chiral degrees of freedom occur in matter and in electromagnetic fields and constitute an area of research that is experiencing renewed interest driven by recent observations of th…
Impact of Spatial Separation of Type-II GaSb Quantum Dots from the Depletion Region on the Conversion Efficiency Limit of GaAs Solar Cells
A. Kechiantz, A. Afanasev, J. -L. Lazzari
The purpose of this work is to look for a practical structure for application of quantum dots (QD) in solar cells in order to enhance sub-band gap photon absorption. We focuse on a…
Tuning up the performance of GaAs-based solar cells by inelastic scattering on quantum dots and doping of AlyGa1-ySb type-II dots and AlxGa1-xAs spacers between dots
A. Kechiantz, A. Afanasev
We used AlGaSb/AlGaAs material system for a theoretical study of photovoltaic performance of the proposed GaAs-based solar cell in which the type-II quantum dot (QDs) absorber is s…
Modification of band alignment at interface of AlyGa1-ySb/AlxGa1-xAs type-II quantum dots by concentrated sunlight in intermediate band solar cells with separated absorption and depletion regions
A. Kechiantz, A. Afanasev, J. -L. Lazzari
We propose a new intermediate band GaAs solar cell comprising an AlxGa1-xAs absorber with built-in GaSb type-II quantum dots (QDs) [a gradual AlxGa1-xAs absorber with built-in AlyG…
Efficiency Limit Of AlxGa1-xAs Solar Cell Modified By AlyGa1-ySb Quantum Dot Intermediate Band Embedded Outside Of The Depletion Region
A. Kechiantz, A. Afanasev, J. -L. Lazzari +3
Recombination through quantum dots (QDs) is a major factor that limits efficiency of QD intermediate-band (IB) solar cells. Our proposal for a new IB solar cell based on type-II Ga…
Efficiency Limit of Intermediate Band AlxGa1-xAs Solar Cell Based on AlyGa1-ySb Type-II Quantum Dots Embedded Outside of the Depletion Region
A. Kechiantz, A. Afanasev, J. -L. Lazzari
The intermediate band (IB) cell is a concept of highly efficient solar cells proposed by Luque and Marti in 1997. The IB concept uses nonlinear effect of two photon absorption enfo…
