Additive effects on electron recombination and transport properties for DSCs using optimum electrolytes. (a) Electron lifetimes (τη) versus photovoltage (Voc) and (b) electron diffusion coefficients (De) versus the short-circuit photocurrent (Jsc), for PMII-0.02 M I2-PC electrolyte without additive as well as in the presence of TBP additive and TBP/GuNCS co-additives. (c) Electron lifetimes (τη) versus Voc, and (d) electron diffusion coefficients (De) versus Jsc, for PMII-0.08 M I2-PC electrolytes without additive, with NMBI and with NMBI-GuNCS co-additives.
