Optical property and orientation-dependent device performance. a Absorption coefficient of the Sb2S3 layer in Sb2S3/TiO2-BnPHJ and the corresponding Sb2S3 layer thickness required to absorb 90% incident photons of a specific wavelength. b Sb2S3/TiO2-BnPHJ device structure (right: cross-sectional SEM characterization). c J–V curves and (d) IPCE spectra of the solar cells based on Sb2S3/TiO2-BnPHJ and ref-Sb2S3/TiO2-BnPHJ (n = 2 for both). e The spatial arrangement of the (Sb4S6)n ribbons tilting 46o on substrate resulting from the [221]-orientation of Sb2S3 cuboids, where the electron transportation along [001] direction is easiest. b Scale bar 400 nm for SEM image
