Investigation the absorption efficiency of GaAs/InAs nanowire solar cells
In this work, the absorption efficiency (Q abs) of GaAs/InAs core-shell nanowires on Si (111)
for normal incident light is investigated. Simulations show the influences of NW diameter on
the Q abs of the structure. Using the finite-difference time-domain (FDTD) and Mie theory,
the highest Q abs for NW solar cells were obtained at a core diameter of 220 nm and a shell
thickness of 35 nm. Additionally, the wavelength-dependent external quantum efficiencies
(EQEs) for NWs were investigated. Numerical simulation of current density-voltage (JV) …

Investigation the absorption efficiency of GaAs/InGaAs nanowire solar cells
This study investigated the absorption efficiency of GaAs/In 0.2 Ga 0.8 As cylindrical core–
shell nanowire (NW) solar cells with a circular cross-section for normal incident light.
Numerical results obtained through finite-difference time–domain simulation showed that
NW dimensions influenced the absorption efficiency of the solar cells. The band structure of
the wires was also investigated.
