title: Fabrication of stable photovoltachromic cells using a solvent-free hybrid polymer electrolyte.
abstract: In this work, photovoltachromic cells (PVCCs) are fabricated using a solvent-free polyethylene glycol (PEG)-titanium hybrid polymer electrolyte. With appropriate addition of 1,2-dimethyl-3-propylimidazolium iodide in the electrolyte, the range of tunable colored-state transmittance of the PVCC is enlarged due to an improved fill factor. A transmittance modulation larger than 40% can be maintained for at least 3 months, demonstrating the good long-term stability of PVCCs fabricated using the solvent-free PEG-Ti hybrid electrolyte.
