Fig. 1: Optical and electrical characterizations of SWCNTs prepared by FCCVD method.
From: High-performance bifacial perovskite solar cells enabled by single-walled carbon nanotubes
a SEM image of the SWCNT film (scale bar = 500 nm). b TEM graph of a SWCNT film, and the average diameter of the individual tube is ~2.5 nm (scale bar = 10 nm). c Optical transmittances of the SWCNT films with various thicknesses. d Sheet resistances of SWCNT films. e Raman spectrum of the SWCNT film, and the high IG/ID ratio is illustrated.
