Enhancing the performance of dye-sensitized solar cells by incorporating nanomica in gel electrolytes☆

Plasma-modified SnO2:F substrate for efficient cobalt selenide counter in dye sensitized solar cell

“…R ct1 , R ct2 , and R ct3 correspond to the charge transfer processes occurring at the counter electrode (corresponding to the rst arc), the TiO 2 -dye-electrolyte interface (corresponding to the second arc), and the Warburg diffusion process of I À /I 3 À in the electrolyte (corresponding to the third arc), respectively. 31,32 The R s values of the Co 0.85 Se-based DSSCs on the pristine and the plasma-treated FTO slides are 18.79 U cm 2 and 17.61 U cm 2 , respectively. Both values are higher than the R s (11.9 U cm 2 ) of the DSSCs fabricated using the Pt CE.…”

“…The impedance spectra were analyzed by an equivalent circuit model that interprets the characteristics of the DSSCs. 31,32 Photocurrent-voltage (I-V) measurements were performed using an AM 1.5 solar simulator equipped with a 1000 W xenon lamp (Model no. 91 192, Oriel, USA).…”

Review on natural dye sensitized solar cells: Operation, materials and methods

“…Lai et al [62] have reported the fabrication of DSSC with gel type electrolyte containing 5 wt% PVDF-HFP in methoxy propionitrile (MPN) and incorporated alkyl-modified nanomica (AMNM) into it. This addition has resulted in an increase of J sc from 8.3 to 13.6 mA/ cm 2 and efficiency from 3.5 to 5.7%.…”

Pt Deposition on Anode Enhances the Performance of Dye-Sensitized Solar Cell with Non-Cross-Linked Gel Electrolyte

“…Since the cell includes electrolyte as one side of the electrodes, the leakage of the electrolyte inevitably limits its durability. As a preferable idea to prevent the electrolyte leakage, gelation of the electrolyte has been proposed [7,8]. Some researchers have been challenging with cross-linking of a polymer [9].…”
