PVdF-HFP/Chitosan Polymer-blend Quasi-solid State Electrolyte for Dye-Sensitized Solar Cells Application

Dye-sensitized Solar Cells (DSSCs) has emerged to become one of the most promising alternatives to conventional solar cells. However, the long term stability and light-to-energy conversion efficiency of the electrolyte in DSSCs are the main challenges towards the commercial use of DSSCs. Liquid elec...
