Abstract :
Pt/Carbon black counter electrode for dye-sensitized solar cells (DSSCs) was prepared by reducing H2PtCl6 with NaBH4 in carbon
black. The Pt/Carbon black electrode had a high electrocatalytic activity for iodide/triiodide redox reaction. Using the Pt/Carbon black
counter electrode, DSSC achieved 6.72% energy conversion efficiency under one sun illumination. Pt/Carbon black electrode shows the
same energy conversion efficiency and lower cost compared with Pt electrode, which makes it available in DSSCs practical applications.
