Variation of the DSCs characteristic parameters as a function of the iodine concentration in the electrolyte. (a) open-circuit potential (Voc), (b) short-circuit photocurrent (Jsc), (c) fill factor (ff), and (d) overall power conversion efficiency (η). Squares correspond to the absence of additive, whereas triangles and circles to the TBP and NMBI addition, respectively.
