Current improvement in substrate structured Sb2S3 solar cells with MoSe2 interlayer |
(a) Raman spectrum of MoSe2. (b) AFM image of MoSe2 atomic layer, the inset shows MoSe2 thickness of around 8 nm, and the step between Mo (dark layer in the center) and MoSe2 was created by a blade. AFM images of (c) Mo surface and (d) MoSe2, their surface roughnesses (Ra) are 3.26 nm and 4.91 nm, respectively. |
