Optimization of poly(vinyl alcohol-co-ethylene)-based gel polymer electrolyte containing nickel phosphate nanoparticles for dye-sensitized solar cell application

For the first time, metal phosphate, particularly nickel phosphate, Ni3(PO4)2 nanoparticle has been incorporated into gel polymer electrolyte (GPE) for the application in dye-sensitized solar cells (DSSCs). Poly(vinyl alcohol-co-ethylene), PVA-co-PE copolymer and sodium iodide, NaI have been employe...
