Zusammenfassung, Abstract
A donor-functionalized spiro-perylenecarboximide (metal-free dye), which contains a perylenetetracarboxylic-derivative and a diphenylamine chromophore, is used as sensitizer for liquid electrolyteand solid-state dye-sensitized solar cells. The corresponding devices generate efficiencies up to 1.72%for electrolyte-based solar cells and 0.2% for solid-state device solar cells measured under illuminationwith simulated sunlight AM 1.5 (100 mW cm-2). The incident photon to current conversion efficiencyreached 63.7% and 7% for liquid electrolyte and solid-state dye-sensitized solar cells, respectively. Theintramolecular charge transfer occurring by through-space charge transfer process between the donorand the perylene dye moiety in the corresponding compound plays an important role in the solarcells performance. We also measure the performance of the parent compound, which contains onlythe perylene tetracarboxylic-derivative chromophore, and, however, the performance is lower than thedonor-functionalized spiro-perylenecarboximide.
