Carbon nanotubes (CNTs)-polymer composite gel electrolyte for solid-state dye sensitized solar cells (DSSCs) |
| 초록 |
Polymer nanocomposite electrolytes have known better thermal, mechanical and ionic conductivity as compared to conventional polymer composites electrolytes due to stronger interaction polymer and nanofiller phases. Recently, CNTs-polymer composite have shown the better interaction in between filler and polymer which are responsible for the enhancement of ion conductivity. Nanocomposite electrolytes are a promising candidate to overcome the linkage and evaporation of liquid electrolyte in dye sensitized solar cells. In this work, we described the preparation of CNTs-polymer (PEO) composite electrolytes and fabricate the solid-state DSSCs. The fabricated DSSCs achieved moderately high conversion efficiency of 3.48% with an open circuit voltage (VOC) of 0.589 volt and short circuit current (ISC) of 10.64 mA/cm2. The highly flexible nature of CNTs could be improved the interaction and cross-linking between nanofiller and polymer molecules which are significantly enhanced the electrical and ion conductivity properties of composite electrolytes. |
