Influence of Parameters of Cold Isostatic Pressing on TiO2 Films for Flexible Dye-Sensitized Solar Cells
Figure 3
SEM pictures of films after various CIP processes. (a) film without CIP; (b) film with a CIP pressure of 50 MPa and holding time 1 s; (c) film with a CIP pressure of 100 MPa and holding time 600 s; (d) film with a CIP pressure of 200 MPa and holding time 600 s. The small inset shows the higher magnifications of each sample. The mark bar for the inset is 1 μm.
