A New Type of Dye‐Sensitized Solar Cell with a Multilayered Photoanode Prepared by a Film‐Transfer Technique

“Basic idea, advance approach”: Efficiency boost by sensitization of blended dye on chemically deposited ZnO films

“…It is interesting to see that Voc (535 mV) and FF (0.57) for blended dye cell is slightly above the average values of the Voc (510 mV) and FF (0.56) for the individual dye cells. Miao et al [46] observed the similar results and Lee et al [47] explained in detail about the variations in Voc for individuals and blended dye structure. The increase in the efficiency for blended structure was mainly due to the increase in Jsc.…”

First application of bis(oxalate)borate ionic liquids (ILBOBs) in high-performance dye-sensitized solar cells

“…In the Figure, typical Nyquist plots of DSCs are demonstrated, in which three semicircles are involved. [18][19][20] As has been stated many times in previous publications, the one in the middle-frequency region reflects the resistance of the charge recombination, R ct2 . Meanwhile, the charge transfer resistance of I 2 /I 3 2 on the counter electrodes appears in the high-frequency region (R ct1 ) and the information related to the Nernst diffusion within the electrolytes that should be a ILBOB is acting as the additive in the electrolytes A-H.

Vanadium oxide as new charge recombination blocking layer for high efficiency dye-sensitized solar cells

“…This surface barrier reduces the back charge transfer recombination rate and thus increases device performance. 16,23,24,26,27 In this work, we report a solution-processed and cost-effective vanadium (V) oxide (V2O5) as a novel charge recombination blocking layer for higher efficiency in DSCs. To the best of our knowledge, this is the first time for V2O5 to be used as charge recombination blocking layer.…”
