Preparation of well-interconnected TiO2 electrodes at low temperature is critical for the fabrication of
highly efficient dye-sensitized solar cells (DSCs) on plastic substrates. Herein we explore a synergistic
approach using a combination of chemical and physical sintering. We formulate a binder-free TiO2 paste
based on “nanoglue” as the chemical sintering agent, and use it to construct a photoelectrode on plastic
by low-temperature physical compression to further improve the connectivity of TiO2 films. We
systematically investigated the factors affecting the photovoltaic performance and found the conditions
to achieve electron diffusion lengths as long as 25 mm and charge collection efficiencies as high as 95%,
as electrochemical impedance spectroscopy measurements indicate. We apply this approach to obtain a
DSC deposited on plastic displaying 6.4% power conversion efficiency based on commercial P25 titania
particles
