Inverted organic solar cells have advantages over conventional organic solar cells. Most important advantage is the improved stability of inverted solar cells. In this study, benzodithiophene, quinoxaline and selenophene bearing conjugated polymer was used as donor material in inverted solar cell applications. Device performances were investigated with the device configuration of ITO/ ZnO/ polymer:PC71BM/ MoO3/ Ag. In order to improve device performance, polymer PCBM ratio, active layer thickness, annealing time and temperature optimizations were carried out. Active layer morphologies were investigated by TEM and AFM analyses. Best performance device showed power conversion efficiency of 2.57 % with VOC of 0.67 V, JSC of 7.68 mAcm-2 and FF of 50 %.

Semiconductor-hydrogen technology
Bayer, I; Eroğlu, İnci; Turker, L (1996-06-28)
Photoelectrochemical (PEG) solar cells are devices that convert solar energy directly into electricity or chemicals. Semiconductor-hydrogen technology, therefore is quite important for stable conversion devices. For production of a chemical fuel semiconductor can serve as a catalyst (1). Electricity producing solar cells are regarded as one of the most important auxiliary equipment for hydrogen production. Moreover, they can be the source for hydrogen. Their design criteria involve investigation of a large ...
PASSIVATION OF SILICON SOLAR CELLS VIA LOW TEMPERATURE WET CHEMICAL OXIDATION
KÖKBUDAK, GAMZE; Çiftpınar, Emine Hande; DEMİRCİOĞLU, OLGU; Turan, Raşit (2016-12-01)
In the development of high efficiency crystalline Si solar cells, decreasing bulk and surface recombination velocities of the minority carriers is vital. As the bulk recombination could be suppressed by enhancing the material quality, the effect of surface recombination on cell performance becomes more dominant. Also, recent studies have revealed that the area under the metal contacted region needs to be passivated to minimize the carrier recombination. The passivation of front and back surface of the cell ...
Selective emitter formation via single step doping through laser patterned mask oxide layer for monocrystalline silicon solar cells
Çiftpınar, Emine Hande; Turan, Raşit; Department of Physics (2014)
Selective emitter is one of the new approaches for higher efficiency solar cells. Although selective emitter cells could be processed by several different methods such as; etch back process, laser doping, ion implantation, doping paste, a different method based on diffusion through a laser patterned oxide layer was studied in this thesis. Utilization of pattern oxide layer as a diffusion barrier enables to obtain selective emitter profile via single step doping which reduces overall production cost and time...
Analysis of boron doped hydrogenated amorphous silicon carbide thin film for silicon heterojunction solar cells
Salimi, Arghavan; Turan, Raşit; Department of Micro and Nanotechnology (2019)
Silicon based solar cells are the dominant type of solar cells in the photovoltaic industry. Recently, there have been increasing efforts to develop c-Si solar cells with higher efficiency and lower cost. Among them, silicon heterojunction solar cell (SHJ) is attracting much attention because of its superior performance values demonstrated at both R&D and industrial levels. One of the common limiting criteria is the recombination at the front side which can be solved by providing proper passivation at the f...
Poly(triphenylamine-thiazolo[5,4-D]Thiazole) copolymers dye for bulk heterojunction organic solar cells
Çırpan, Ali; Gülfen, Mustafa; Uğurlu, Çiğden; Hızalan, Gönül; Toppare, Levent Kamil (2018-07-06)
The polymer-based solar cells (PSCs) are promising due to their simple fabrication procedure, low material cost and flexibility. In recent years, PSCs based on the conjugated polymers as the electron donor materials blended with [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) have been investigated extensively using a single bulk heterojunction (BHJ) device structure. The semiconductivity and solar cell material properties of thiazolo[5,4- d]thiazoles have been investigated previously [1,2]. In the pres...
