以甲基丙烯酸羟基乙酯和N-乙烯基吡咯烷酮为单体,采用溶液共聚法制备了一系列的P(HEMANVP)共聚物.利用此共聚物固化液态电解质得到准固态电解质.考察了NVP用量、引发剂用量(AIBN)以及交联剂用量对准固态电解质电导率的影响.经过优化后,这种共聚物形成的准固态电解质最高室温电导率为6.15mS/cm,利用此电解质组装的染料敏化太阳能电池在100mW/cm~2(AM1.5)的模拟光照下,其短路电流、开路电压、填充因子和光电转化效率分别为14.83mA/cm~2、615mV、0.5721、5.22%.

A series of copolymers P(HEMA-NVP) composed of hydroxy ethyl methacrylate(HEMA)and N-vinyl pyrrolidone(NVP)are prepared by a solution copolymerization technique.The copolymer can absorb and capture amount of liquid electrolyte within its chain networks structure to form quasi-solid-state electrolyte.The influences of synthesis conditions for copolymers,such as the content of NVP,the amount of initiator AIBN,and the amount of crosslinking agent TEGDMA on the ionic conductivity of quasi-solid electrolyte are investigated.The highest conductivity of the copolymer gel is 6.15mS/cm at 25℃.Based on the copolymer gel electrolyte,a dye-sensitized solar cell is fabricated with short-circuit current of 14.83mA/cm~2,open circuit voltage of 615mV,fill factor of 0.5721 and an overall conversion efficiency of 5.22% under 100 mW/cm~2 irradiation(AM1.5).
