- We developed low temperature fabrication method for the bendable electrode, simply by blending of
PMMA with TiO2, providing flexibility to the plastic dye-sensitized solar cells (DSSCs). Contrary to the
conventional structure of photoelectrode, proposed electrode consists of elastic polymer and inorganic
materials. It is expected that elastic polymer could absorb the external impact like bending, retarding the
crack propagation into the interconnected TiO2. We confirmed that composite photoelectrode displayed
good bending rigidity. Regarding photovoltaic properties, the open circuit voltage gradually increased
with the polymer content, suggesting that formation of thin polymer layer on TiO2 particles suppressed
the recombination at TiO2/electrolyte interface.
