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 characteristics and the selective coating capabilities of prepared ethanol and isopropanol based EPD solutions and their acetylacetone additive (as surfactant) alternatives were investigated using zeta potential measurements and mean colloid size analysis. As a subsequent complementary process, deposited films were compressed using Cold Isostatic Pressing (CIP) with an alternative clamping-effect pressure profile in order to increase the interparticular coherence and the overall adherence of the film onto substrates. Having obtained a 14-16 mu m film thickness values, cells were assembled with active area values of 0.5 x 0.5 cm(2), 1.0 x 1.0 cm(2) and 2.5 x 2.5 cm(2) and solar measurements were conducted, resulting in up to 4.22%, 4.13% and 4.00% efficiencies, relatively, under AM 1.5 conditions.

Production of flexible polymeric photoanodes using binder-free electrophoretic deposition and compression for dye-sensitized solar cells Kocaoglu, Bahadir Can; Özenbaş, Ahmet Macit (2015-04-29) 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 suspension...
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...
Tuning the electron beam evaporation parameters for the production of hole and electron transport layers for perovskite solar cells Coşar, Mustafa Bura; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2019) This study evaluates the use of electron beam evaporation technique for the deposition of electron and hole transport layers for perovskite solar cells where cell productions were performed in n-i-p structure. NiO and TiO layers were studied for hole transport layer and TiO2 and Nb2O5 layers were deposited for electron transport purposes. To optimize the suitable evaporation parameters for efficient perovskite cell production, single layers of each material were deposited at different conditions of oxygen f...
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...
Simulation of an efficient silicon heterostructure solar cell concept featuring molybdenum oxide carrier-selective contact MEHMOOD, Haris; NASSER, Hisham; Tauqeer, Tauseef; HUSSAIN, Shahzad; Ozkol, Engin; Turan, Raşit (2018-03-25) Transition metal oxides/silicon heterocontact solar cells are the subject of intense research efforts owing to their simpler processing steps and reduced parasitic absorption as compared with the traditional silicon heterostructure counterparts. Recently, molybdenum oxide (MoOx, x<3) has emerged as an integral transition metal oxide for crystalline silicon (cSi)-based solar cell based on carrier-selective contacts (CSCs). In this paper, we physically modelled the CSC-based cSi solar cell featuring MoOx/intr...
