Abstract
Recently, antimony sulfide (Sb2S3) has received intense attention as a light absorber material for solar cell due to its appropriate band gap (1.7-1.8 eV), low cost, non-toxicity, and high stability. In this study, Sb2S3 was deposited through a simple spin-coating process using an antimony-complex precursor solution prepared by dissolving antimony oxide (Sb2O3), carbon disulfide (CS2), and n-butylamine in an ethanol solvent. The power conversion efficiency (PCE) of 3.5% was obtained under AM1.5G illumination in a planar type device consisting of FTO/Cs2CO3 treated TiO2/Sb2S3/P3HT/Au, which is significantly higher than that of the control device without Cs2CO3 treatment (2.7%). The higher PCE of planar type Sb2S3 solar cell based on Cs2CO3 treated TiO2 electron conductor is attributed to uniform surface formation, suitable energy level alignment, and efficient electron transport properties.
