  Electrolytes for Dye-Sensitized Solar Cells Based on Interhalogen Ionic Salts and Liquids

  摘要：

  In this paper, we report on the preparation of interhalogen ionic liquids of the general formula [K+]XY2-, where K+ = 1,3-dialkylimidazolium, 1,2,3-trialkylimidazolium, or N-alkylpyridinium; XY2- = IBr2- or I2Br-. These compounds were characterized in solution and the solid state by NMR, IR, Raman, and mass spectroscopy. The crystal structure of the compound [Me(2)BuIm]IBr2 (7) shows that the IBr2- anion has a linear Br-I-Br structure. Indications of an equilibrium between different forms of XY2- anions in solution are observed. Interhalogen ionic salts and liquids were used as electrolyte components for encapsulated monolithic dye-sensitized solar cells. Overall light-to-electricity conversion efficiencies up to 6.4%, 5.0%, and 2.4% at 1000 W/m(2) were achieved by using electrolytes based on interhalogen ionic salts and gamma-butyrolactone, glutaronitrile, or native ionic liquids as solvents, respectively. Moreover, in terms of stability, the cell performance lost 9-14% of the initial performance after 1000 h illumination at 350 W/m(2).

  阴离子亲核试剂在离子液体和分子溶剂中的反应性

  摘要：

  在[hmim] [ClO 4 ] 3i，[hm 2 im] [ClO 4 ] 3'i和[hmim] [PF 6 ] 3l ILs中，在与n甲磺酸烷基酯，并与普通分子溶剂（MeOH，DMSO，PhCl）中的烷基磺酸盐进行比较。发现反应性既取决于咪唑阳离子与阴离子的相互作用，又取决于IL中存在的水的特定溶剂化作用，水起主要作用，尤其是亲水性阴离子。去除最大量的水可显着提高IL中的离子对反应性，直至速率常数k 与在DMSO和低极性介质（PhCl）中获得的结果相当。

  Disclosed are a novel dye, having a dispersant functional group to simultaneously exhibit a dye function and a dispersant function, and a dye-sensitized solar cell including the same. According to this invention, the dye may simultaneously manifest a dye function for absorbing light, made possible by being adsorbed on the entire surface of metal oxide particles, to thus produce excited electrons which are then transferred into a conduction band of metal oxide, and a dispersant function for preventing the agglomeration of the particles to thus improve the uniformity of the metal oxide particles in a paste and film density.
