摘要：
New binary ionic liquid electrolytes based on 1-methyl-1-butylpyrrolidinium bis(trifluromethylsulfonyl)imide, 1-butylpyridinium bis(trifluromethylsulfonyl)imide, 1-methyl-3-ethylimidazolium bis(trifluromethylsulfonyl)imide, 1-methyl-3-ethylimidazolium tetracyanoborate, or 1-methyl-3-ethylimidazolium tricyanomethanide coupled with 1-methyl-3-propyl-imidazolium iodide were developed for dye-sensitized solar cells (DSCs). We examined these ionic liquid compositions in conjunction in conjunction with a diketopyrrolopyrrole-based donor-bridge acceptor dye (DPP-13) in dye-sensitized solar cells and also investigated the influence of adding lithium ions to the electrolyte to enhance the device performance. The best device exhibited a short-circuit current density of 15.2mAcm(-2), an open-circuit voltage of 678mV, and a fill factor of 71%, corresponding to an overall power conversion efficiency (PCE) of 7.1% under standard AM1.5G illumination at 100mWcm(-2).
