Research Abstract |
TiO2 films were prepared using a paste mixture of titania and size-controlled squid ink particles that was used to manufacture macroporous electrodes in a dye-sensitized solar cell (DSSC). The sintering procedure at 450 °C decomposed the ink particles, thereby increasing the porosity of the structure in the films. An increase in the proportion of ink particles in the paste formulation increased the surface roughness of the films. The ink particles in the paste consequently enhanced the film porosity. The TiO2 films prepared using a paste mixture consisting of 30% ink particles had the roughest surface, but its DSSC had the lowest photoelectric conversion efficiency. Thus, this study revealed the effects of the paste composition on the TiO2 film morphology and DSSC performance.
