Optimization and analysis on $Sb_2Se_3$ solar cells fabricated via vapor deposition methods

Abstract

Antimony Selenide is a binary chalcogenide compound, which has adequate bandgap, high absorption coefficient and one dimensional ribbon structure that lowers carrier recombination. These properties make $Sb_2Se_3$ a promising material for next generation solar cells. Since the first efficiency reported on make $Sb_2Se_3$ thin film solar cells, it has increased until now up to almost 8%, showing a fast grow in performance. In this study, explanation of make $Sb_2Se_3$ thin film solar cells fabricated via various vapor deposition are explained. In addition, optimization is done through variable control and analysis. In addition, power conversion efficiency over 5% was reached through Vapor Transport Deposition.
