Figure 7From: The influence of anatase-rutile mixed phase and ZnO blocking layer on dye-sensitized solar cells based on TiO2nanofiberphotoanodesPhotocurrent-voltage curves of TiO 2 nanofiber cells (sintered at 550°C and approximately 60-μm thick). With ZnO layer of different thicknesses (4 to 20 nm).Back to article page
