Interface Tuning Approach for High Performance I2-Free Solid-State Dye-Sensitized Solar Cells |
| 초록 |
We report I2-free solid-state dye-sensitized solar cell (ssDSSC) with 6.8 % energy conversion efficiency, one of the highest for N719 dye, as a result of enhanced transmittance of nanostructured interfacial layer and high conductivity of hole transporting material (HTM). The excellent performance was achieved via careful control of the electrode/HTM and nanocrystalline TiO2/conducting glass interfaces. Solid-state polymerized conducting polymers, poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(3,4-ethylenedithiathiophene) (PEDTT), deeply infiltrated into the TiO2 pores and functioned as an HTM. Furthermore, transparent organized mesoporous 550-nm-thick TiO2 film with high porosity and good connectivity improved cell performance due to the increased transmittance of visible light, decreased interfacial resistance and enhanced electron lifetime. |
