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.

Optimization of Selective Electrophoretic Deposition and Isostatic Compression of Titania Nanoparticles for Flexible Dye-Sensitized Solar Cells Kocaoglu, Bahadir Can; Icli, Kerem Cagatay; Özenbaş, Ahmet Macit (2016-04-01) Flexible photoanodes on PEN/PET based substrates for dye-sensitized solar cells (DSSC) by using electrophoretic deposition (EPD) method for the formation of titania nanoporous layer with titania nanoparticles (P-25) were produced. Considering commercially available titania nanoparticles containing both anatase and rutile phases, the undesired rutile nanoparticles, for DSSC applications, were almost eliminated from the coatings by selective pH adjustment of the EPD solutions without any binders. The coating ...
Production and development of flexible dye sensitized solar cells / Kocaoğlu, Bahadır Can; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2014) Electrophoretic Deposition (EPD) of titania nanoparticles (P-25 Degusa) have been utilized in order to form the nanoporous photoanodes of dye-sensitized solar cells (DSSCs) on flexible polymeric (PEN) substrates. Highly uniform, adherent nanoporous thick films were produced by uniformly dispersing the titania nanoparticles in alcohol based solutions without any binders. Solution performances of each type of alcohols and mixtures of which have been examined considering their coating thickness, morphology and...
Production of core-shell type conducting FTO/TiO2 photoanode for dye sensitized solar cells Icli, Kerem Cagatay; Yavuz, Halil Ibrahim; Özenbaş, Ahmet Macit (2014-02-01) Core-shell type photoanode composed of electrically conducting fluorine doped tin dioxide (FTO) matrix and TiO2 shell layer was prepared and applied in dye sensitized solar cells. Effects of fluorine doping on tin dioxide based cells and precursor material on shell layer were investigated. Fluorine doped tin dioxide nanoparticles were synthesized under hydrothermal conditions and resistivity value down to 17 Omega cm was achieved. Cells constructed from FTO nanoparticles show enhanced performance compared t...
Fabrication and characterization of PEDOT:PSS hole transport layers for silicon solar cells Türkay, Deniz; Yerci, Selçuk; Department of Micro and Nanotechnology (2019) Heterojunction silicon solar cells have gained considerable interest in recent years with the demonstration of record-high device performances. However, these devices are typically based on inorganic layers fabricated at high temperatures under vacuum environment, using toxic precursors. The low temperature budget, non-toxic chemical contents, and wide range of adjustability in physical and electrical properties make poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) a promising candidate a...
Synthesis of novel diketopyrrole and selenophene containing nir absorbing polymers and their application in bulk-heterojunction solar cells Öklem, Gülce; Günbaş, Emrullah Görkem; Department of Polymer Science and Technology (2017) DPP-based conjugated polymers are recently used in organic light emitting diodes, electrochromic devices, organic field effect transistor and organic solar cell applications. Their advantageous properties, such as broad optical absorption in Near Infra Red (NIR) region, high charge carrier mobility and good film forming ability make them an excellent choice for generation of highly efficient solar cells. In this thesis, using donor-acceptor approach (D-A) we aimed to synthesize novel polymers with furan bas...
