Effect of Hydroquinone Dderivatives in Electrolytes on Dye-Sensitized Solar Cell Performance
نویسندگان
چکیده مقاله:
New kinds of hydroquinone derivatives were synthesized and along with a azo dye applied as additives in the iodide/iodine redox electrolyte for dye-sensitized solar cells and their effect on the short-circuit photocurrent of dye sensitized solar cells was investigated. Addition of 0.05 M a hydroquinone derivative in the electrolyte comprising 0.5 M 1-methyl-3-propylimidazolium iodide (MPII) and 0.05 M I2 in a mixture of acetonitrile and valeronitrile (volume ratio, 85:15) enhanced significantly photocurrent density from 11.1 to 12.8 mA/cm2, and voltage increased from 0.66 to 0.68 V. As a result, overall conversion efficiency increased from 4.4% to 4.8%, corresponding to increment of 10.9%.

متن کاملEffects of Sensitization with Natural Pigments on the Performance of Dye-sensitized Solar Cell (DSSC)
Three natural pigments including wild iris, black pomegranate bark and black grapes were used as sensitizer in dye sensitized solar cells (DSSCs) based on TiO2 nanoparticles. The results showed that the DSSC made of black pomegranate bark was more efficient than the other cells due to its strong bonding with TiO2 nanoparticles. Longer electron lifetime, lower electron recombination, and lower...

متن کاملDye molecules in electrolytes: new approach for suppression of dye-desorption in dye-sensitized solar cells
The widespread commercialization of dye-sensitized solar cells remains limited because of the poor long-term stability. We report on the influence of dye-molecules added in liquid electrolyte on long-term stability of dye-sensitized solar cells. Dye-desorption from the TiO2 surface during long-term cycling is one of the decisive factors that degrade photocurrent densities of devices which in tu...
