Application of azo dye as sensitizer in dye-sensitized solar cells
An azo dye used as photosensitizers in Dye-sensitized solar cells DSSCs. Azo dyes economically superior to organometallic dyes because they are color variation and cheap. The spectrophotometric evaluation of an azo dye in solution and on a TiO2 substrate show that the dye form J-aggregation on the nanostructured TiO2 substrate. Oxidation potential measurements for used azo dyes ensured an energ...
متن کاملA highly efficient organic sensitizer for dye-sensitized solar cells.
We have synthesized a highly efficient organic dye for a dye-sensitized solar cell; the overall solar-to-energy conversion efficiency was 9.1% at AM 1.5 illumination (100 mW cm(-2)): short-circuit current density (J(sc)) = 18.1 mA cm(-2), open circuit photovoltage (V(oc)) = 743 mV and fill factor (ff) = 0.675.
متن کاملNatural Dyes from Roselle Flower as a Sensitizer in Dye- Sensitized Solar Cell (DSSC)
Received Aug 29, 2017 Revised Nov 18, 2017 Accepted Dec 4, 2017 Hibiscus Sabdariffa L. well known as Roselle flower was used as sensitizers for Dye-Sensitized Solar Cell (DSSC). The dyes were extracted using distilled water (DI) and ethanol (E) extract solvent in an ultrasonic cleaner for 30 minutes with a frequency of 37 Hz by using ‘degas’ mode at the temperature of 30°. Doctor blade method w...
متن کاملEfficient thiocyanate-free sensitizer: a viable alternative to N719 dye for dye-sensitized solar cells.
We have designed and synthesized a new thiocyanate-free sensitizer coded as SPS-01 and used it as the sensitizer in a TiO(2) based nanocrystalline dye-sensitized solar cell (DSSC). SPS-01 exhibits strong visible absorption properties with maximum peak around at 532 nm. The overall power conversion efficiency (PCE) of a DSSC sensitized with SPS-01 (7.96%) is higher than that of N719 (7.30%) unde...
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...
