Fig. 2From: Sb2S3 Thickness-Related Photocurrent and Optoelectronic Processes in TiO2/Sb2S3/P3HT Planar Hybrid Solar Cellsa Cross-sectional FE-SEM images of Sb2S3 films on TiO2 dense layer-coated glass substrates. b Average Sb2S3 thickness d plotted as a function of the CBD reaction time t for the Sb2S3 film deposition. The values were estimated by the FE-SEM cross-section imagesBack to article page
