Aqueous Soluble Fullerene Acceptors for Efficient Eco-Friendly Polymer Solar Cells Processed from Ethanol/Water Mixtures |
| 초록 |
We present a new series of fullerene derivatives that exhibit solubility in ethanol/water solvent mixtures and implement these materials to successfully fabricate polymer solar cells (PSCs) using benign solvents. In order to simultaneously optimize the processability of the fullerenes in ethanol/water solvent mixtures and device performance, different fullerene mono-adducts were designed by introducing oligoethylene glycol (OEG) side chains with different lengths and number of branches. As a result, we achieved power conversion efficiencies (PCE) up to 1.4% for PSCs processed from benign ethanol/water mixtures in air. Significantly, the new alcohol/water-soluble fullerene derivatives displayed electron mobilities up to 1.30 × 10-4 cm2 V-1 s-1, 150 times higher than those of a previously reported alcohol-soluble fullerene bis-adduct, owing to efficient packing of the fullerenes. |
