Improvement of Dye Solar Cell Efficiency by Photoanode Posttreatment
Figure 4
Photocurrent density-voltage curves measured under (a) AM 1.5 simulated light intensity at 100 mW/cm2 (1 sun); (b) dark conditions, of DSSCs with untreated photoanode (black full square) and posttreated photoanodes with colloidal treatment at 150°C (red full circle), 350°C (green full triangle), and 450°C (blue full inverted triangle).
