An optimized structure for enhancing optical absorption of solar energy in elliptical GaAs nanowire array solar cell
Nazmus Sakib1, Md. Atiqur Rahman Ahad2.
The enhanced optical absorption of solar energy in a solar cell using nanostructured materials is a very demanding and
important research area. Hence, an optimized structure to increase the optical absorption of solar energy in an elliptical
GaAs (Gallium Arsenide) nanowire array solar cell was proposed in this paper. The influence of geometric parameters
on the optical absorption of elliptical GaAs nanowire solar cells was investigated by exploiting the finite difference in
time domain simulations. Based on the design and analysis, the elliptical GaAs nanowire array performed better than any
circular GaAs nanowire. It was found that the enhanced performance was due to the reduced reflection from the top surface
and a reduced transmission from the bottom surface of the elliptical GaAs nanowire array. The structural parameters of
the elliptical GaAs nanowire were optimized by calculating the short circuit current density (Jsc) for different geometries
over the solar spectrum. It was demonstrated that there was an increase of 9.4% in the Jsc compared with the circular GaAs
nanowire under the optimized conditions.
