Figure 3From: The influence of anatase-rutile mixed phase and ZnO blocking layer on dye-sensitized solar cells based on TiO2nanofiberphotoanodesXRD patterns. ZnO layers deposited on glass substrate (a) and UV–vis transmission spectra for the FTO substrate without and with ZnO layers (b). The inset in b is the SEM photo of FTO substrate covered with 15-nm-thick ZnO film.Back to article page
