| 2 | Optimization of polymer electrolytes forquasi-solid-state dye-sensitized solar cells显示文摘The photoelectrochemical properties of the quasi-solid-state dye-sensitized solar cells based on polymer electrolytes consisting of polyethylene oxide (PEO) with the additions of nano-TiO2 and ionic liquid of MPII (1-methyl-3-propylimidazolium iodide) were studied. By using a composite polymer electrolyte of PEO︰LiI︰TiO2︰ MPII︰I2 = 3︰3︰3︰7︰1 (in mol ratio), the solar energy conversion efficiency of 3.2% under 100 mW·cm?2 was ob- tained, which was 8 times higher than that of the cell using polymer electrolyte without any additives. The effect of the additives was attributed to the increase of ionic conductivity of the polymer electrolytes. | ZHANGChangneng WANGMiao ZHOUXiaowen LINYuan FANGShibi LIXueping XIAOXuri CENKuang | 2004 | Chinese Science Bulletin2004，49，19： | 0 |
