Electrolytes were injected through holes in dye‐sensitized solar cells (DSSCs), and the holes were subsequently sealed with UV‐curable adhesives containing different types of acrylate monomers and different amounts of fluorosurfactants, which were found to affect the performance of the DSSCs during long‐term stability tests. The efficiency ( η ) of the DSSCs' conversion of light to electricity is an important parameter. The corrosion potential ( E corr ) toward the liquid electrolyte and the adhesion strength of the UV‐curable adhesives to fluorine‐doped tin oxide (FTO) glass affected the efficiency of DSSCs during long‐term thermal stability tests. The UV‐curable adhesive containing 10.0 wt % of acrylic acid (AA) monomer and 3.0–4.0 wt % of fluorosurfactant, when used to seal DSSC devices, led to the best DSSC performance of η = 4.1% during a 45‐day long‐term thermal stability test. © 2019 Wiley Periodicals, Inc.
