摘要：

Quasi-solid-state dye-sensitized solar cells (DSSCs) are fabricated using acetamide-modified PEO/P(VDF-HFP) composite polymer electrolytes (CPEs) along with KI and I-2. The DSSC assembled with acetamide-modified CPE shows higher open-circuit voltage and higher short-circuit photocurrent density than those of DSSC with unmodified CPE. With moderate acetamide content (0.20 g) modification, the DSSC exhibits a 14.3 mV improvement of photovoltage, a 2.83 mA cm(-2) improvement of current density and a improved performance of 6.04% compared with 4.68% of the original DSSC. Variations in the V-oc and J(sc) are explained in terms of shift of the flat band potential of TiO2 and a complex formation between I-3(-) and -NH2 of acetamide in the electrolyte.
