Abstract Optimization of GaSb/GaAs quantum dot (QD) size and density for photovoltaics is
theoretically studied by performing simulation in a two-dimensional (2D) aspect. A layer of …

Abstract Two-dimensional (2D) simulation of GaAsSb/GaAs quantum dot (QD) solar cells is
presented. The effects of As mole fraction in GaAsSb QDs on the performance of the solar …

The main limitations of the conventional solar conversion device is that low energy photons
cannot excite charge carriers to the conduction band, therefore do not contribute to the …

The purpose of this work is to look for a practical structure for application of quantum dots
(QDs) in solar cells. We focus on a stack of strain‐compensated GaSb/GaAs type‐II QDs. We …

In this work, we have studied the GaSb/GaAs Quantum Dot Solar Cell for different number of
quantum dot layers, the short circuit current, the open circuit voltage, the fill factor and the …

Quantum dot solar cells (QDSC) have been extensively studied by various researchers for
the last 15 years as they have much higher conversion efficiency and it is capable of …

Theoretical model and numerical analysis of charge accumulation within a single GaSb
quantum dots layer embedded in GaAs-based Schottky diode is performed. We hereby give …

GaSb quantum dot (QD) solar cell structures were grown by molecular beam epitaxy on
GaAs substrates. We investigate the reduction in open-circuit voltage and study the …
