Out of the main challenge facing dye sensitized solar cells (DSSCs) is the leakage and vaporization of liquid electrolyte limiting the long term durability of these cells. Therefore, solidification of electrolyte in DSSCs is a crucial research direction. In this work, DSSC was assembled using electrolyte system composed of Chitosan as host polymer, ethylene carbonate as plasticizer, LiI: I 2 as redox couple and TiO 2 as filler; TiO 2 modified with WO 3 photoanode to provide inherent energy barrier and anthocyanin as sensitizer. The obtained solar cell conversion efficiency was about 1.8% with fill factor 53% using an irradiation of 100 mW/cm 2 at 25 °C. The prepared DSSC is not only stable but also eco friendly due to use of natural polymer and dye. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 630–634, 2019
