Current improvement in substrate structured Sb2S3 solar cells with MoSe2 interlayer |
UPS of (a) Sb2S3 film and (b) Mo film, showing the work functions of Sb2S3 and Mo being 4.27 eV and 4.86 eV, respectively. (a)Φ Sb2S2 = Ehν – (EF – Ecutoff) = 21.22 – (21.08 – 4.13) = 4.27 eV. (b)Φ Mo = Ehν – (EF – Ecutoff) = 21.22 – (21.08 – 4.72) = 4.86 eV. |
