Porphyrin dye-sensitised solar cells utilising a solid-state electrolyte.
We describe a porphyrin dye-sensitised solar cell utilising a solid state electrolyte containing the I(-)/I(3)(-) redox couple, which yields a performance of 5.3% under moderate light intensity and 4.8% at full sun.
متن کاملContribution from a hole-conducting dye to the photocurrent in solid-state dye-sensitized solar cells.
The hole transporting medium in solid-state dye-sensitized solar cells can be utilized to harvest sunlight. Herein we demonstrate that a triphenylamine-based dye, used as hole-transporting medium, contributes to the photocurrent in a squaraine-sensitized solid-state dye-sensitized solar cell. Steady-state photoluminescence measurements have been used to distinguish between electron transfer and...
متن کاملNatural dyes extracted from black carrot and bramble for Dye-Sensitized Solar Cells
Two different natural dyes containing anthocyanin extracted from black carrot and bramble from Iran. Spectrophotometric evaluations of the natural dyes in solution and on a TiO2 substrate were carried out in order to assess changes in the status of the natural dyes. The results show that the natural dyes indicate buthochromic shift on the TiO2 substrates. The chemical adsorption of natural dyes...
متن کاملButyronitrile-based electrolyte for dye-sensitized solar cells.
We elaborated a new electrolyte composition, based on butyronitrile solvent, that exhibits low volatility for use in dye-sensitized solar cells. The strong point of this new class of electrolyte is that it combines high efficiency and excellent stability properties, while having all the physical characteristics needed to pass the IEC 61646 stability test protocol. In this work, we also reveal a...
