中文摘要It was observed that the ionic conductivity of the solid-state electrolyte LiI/3-hydroxypropionitrile (HPN) = 1:4 (molar ratio) decreased dramatically with increasing iodine (h) concentration, which differs from the conduction behavior of the Grotthuss transport mechanism observed in liquid or gel electrolytes. The short-circuit photocurrent density (J(sc)) of the dye-sensitized solar cell (DSSC) based on this electrolyte system increases with increasing I-2, concentration until LiI/I-2 is 1:0.05 (molar ratio). Beyond this limitation, the J(sc) decreases. At low I-2 concentrations (I-2/LiI <= 0.05), the Jsc, is mainly affected by the diffusion of I-3(-). An increase of the I-2 concentration leads to the enhancement of the diffusion of I-3(-) and an increase of the Jsc. At high I-2, concentrations (I-2/LiI > 0.05), the factors, including the increased light absorption by the I-3(-), the increased recombination of electrons at the photoanode with I-3(-), and the reduced ionic conductivity of the electrolyte, lead to a decrease of J(sc). At the same time, the open-circuit voltage (V-oc) of the DSSC decreases monotonically with the ratio of I-2/LiI due to increased dark current in the DSSC. The increased absorption of visible light by the electrolyte, the enhanced dark current, and the reduced ionic conductivity of the electrolyte contribute to the performance variation of the corresponding solid-state DSSC with increasing 1, concentration.
