Investigating the Role of I2SCN− on the Fermi Level of Electrolyte for Dye-Sensitized Solar Cells

Optimization of hierarchical light-scattering layers in TiO2 photoelectrodes of dye-sensitized solar cells

“…Electrochemical impedance spectroscopy was used to investigate the effect of scattering layers on the electron transfer kinetics of the TiO 2 photoelectrodes under 1 sun illumination and open circuit conditions (Nath et al, 2015a(Nath et al, ,b, 2013a. Fig.…”

“…The dye-adsorbed TiO 2 films were rinsed with anhydrous ethanol and dried quickly under a slow flow of N 2 gas (Nath et al, 2013a,b,c). The counter electrodes were prepared by spin coating 5 mM chloroplatinic acid hexahydrate onto FTO glass substrates which were subsequently annealed in air at 380°C for 20 min (Nath et al, 2015a(Nath et al, ,b, 2012. The dye-loaded TiO 2 photoelectrodes and platinized counter electrodes were attached using a 50 lm Surlyn film as a spacer and sealant (Nath et al, 2013a,b,c).…”

Toward Sustainable, Colorless, and Transparent Photovoltaics: State of the Art and Perspectives for the Development of Selective Near‐Infrared Dye‐Sensitized Solar Cells

“…[218] Nath et al have examined both interhalogen and pseudohalogen redox couples (I − ,Br − / I 2 − ,I 2 Br − ) and (I − ,SCN − / I 3 − ,I 2 SCN − ) (Table 10 entry 1 and 2). [219,220] The formation of the interhalogen ion, determined via ESI-MS, was characterized by cyclic voltamperometry. It was found a more positive redox potential than the benchmark I 3 − /I − redox couple.…”

Halogen-free guanidinium-based perovskite solar cell with enhanced stability

“…The incorporation of SCN − groups into the sensitizer or redox couple of a dye-sensitized solar cell (DSSC) has been shown to be a useful strategy to enhance the cell performance. 17,18 PSCs based on MAPbI 3− x (SCN) x exhibit better intrinsic stability in humid air than conventional MAPbI 3 perovskite. 14,15,19 The strong interaction between SCN − and Pb 2+ contributes to improving the humid air stability of the perovskites.…”
