Optimization of AlSb Solar Cell to Improve PCE

Abstract

This research work investigates the new prospects in Aluminium Antimonide (AlSb) compound solar cell by numerical analysis. AlSb is a material of binary compound semiconductor group with suitable electrical and optical properties to have a highly efficient and stable solar cell. In this research paper, an optimization of AlSb solar cell is analyzed numerically with simulation software for the analysis of microelectronic and photonic structures named AMPS 1D. It is explored that, the cell conversion efficiency is 18.07% (Jsc = 21.342 mA/cm2, FF = 0.703, Voc = 1.20 V) with a thickness of 1 μm of absorber layer in AlSb solar cell. The proposed cell structure is almost stable with only a small degradation in efficiency with temperature variation. The overall analytical result shows AlSb solar cell as a potential candidate in uprising photovoltaic applications with better efficiency and stability.
