Efficient Binary Organic Redox Mediators in Dye-Sensitized Solar Cells based on Carbon Black Counter Electrode |
| 초록 |
Dye-sensitized solar cells (DSCs) have achieved energy conversion efficiencies of over 11 % with an electrolyte based on an iodide/triiodide (I-/I3-) redox shuttle. Even though the I-/I3- works efficiently, it retains however some drawbacks such as visible light absorption and metal electrode corrosion. Herein, we present a binary organic redox mediator combining two different thiolate/disulfide redox couples. Aiming at the increment of fill factor, carbon black counter electrode was applied on binary redox couples-based DSCs to reduce the charge transfer resistance at the counter electrode. As a result, we achieved 1.57 times improvement in efficiency under standard illumination conditions. |
