Studies on Alternate Counter Electrode Materials for Pt—Free Dye Sensitized Solar Cells

Counter electrode selection has been a major challenge that directly affects the performance of dye sensitized solar cells. Platinum being a non-reactive metal is the most accepted material as counter-electrode, however, it has limitations due to its high cost and scarcity. In the present work, we have studied cost effective carbon based materials as alternate electrodes in dye sensitized solar cells.
