Figure 1From: Influence of electrolyte co-additives on the performance of dye-sensitized solar cells Variation of the DSCs characteristic parameters as a function of the iodine concentration in the electrolyte. (a) open-circuit potential (V oc), (b) short-circuit photocurrent (J sc ), (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.Back to article page
