Electrophoretic deposition (EPD) of titania nanoparticles have been utilized in order to form the nanoporous photoanodes of dye-sensitized solar cells (DSSCs) on flexible polymeric (PEN/PET) substrates. Highly uniform, adherent nanoporous thick films were produced by uniformly dispersing the titania nanoparticles in alcoholic suspensions without any binders. Suspension performances of each type of isopropanol based mixtures have been examined. Additionally, the effect of acetylacetone addition in suspensions on zeta potential and effective particle size of the colloids is investigated. EPD process has been conducted in single step while the uniformity of the morphology and the thickness of the films were maintained preventing the damage on ITO layer due to excessive voltage exposure. Subsequently, the mechanical compression is applied via cold isostatic pressing (CIP) with a pressure profile in order to obtain 12-14 mu m film thickness and photon to current conversion efficiency of 2.16 % was obtained under AM1.5 conditions.
