Abstract

Thin-film solar cells have attracted worldwide attention due to their high efficiency and low cost. Antimony selenide (Sb2Se3) is a promising light absorption material candidate for thin-film solar cells due to its suitable band gap, abundance, low toxicity, and high chemical stability. Herein, we fabricate an Sb2Se3 thin film solar cell using a simple hydrazine solution process. By controlling the thickness of the photoactive layer and inserting a poly(3-hexylthiophene) hole-transporting layer, an Sb2Se3 solar cell with a power conversion efficiency of 2.45% was achieved.
