摘要: For the application to quasi-solid state dye-sensitized solar cells (QS-DSSCs), we have prepared composite polymer electrolytes with a poly(ethylene oxide) (PEO)-TiO2-LiI-I2 system. Effects of concentration TiO2 nanofiller on electrochemical properties PEO-based been investigated. The experimental results show that presence in electrolyte changes phase polymer. Also, addition noticeably increases ionic conductivity electrolytes. At optimized 15 wt%, exhibited maximum value conductivity, and leads remarkable enhancement photovoltaic performance QS-DSSC. This indicates incorporation gives rise reduction crystallinity mobility I−/I3− redox couple, resulting current density
