A new metamaterial absorber structure is designed and characterized both numerically and experimentally for microwave energy harvesting applications. The proposed structure includes four wheel resonators with different dimensions, from which the overall response of the structure can then be obtained by summing all the overlapping frequency responses corresponding to each dimension. The essential operation frequency range of the wheels is selected in such a way that the energy used in wireless communications and found within the environment that we live is absorbed. The dimensions are obtained using parametric study and genetic algorithm to realize wideband absorption response. When the simulation and measurement results are taken into account, it is observed that the metamaterial absorber based harvester has potential to absorb and convert microwave energy with an absorption ratio lying within the range of 80 and 99% for the frequency band of 3-5.9 and 7.3-8 GHz. The conversion efficiency of the structure as a harvester is found to be greater than 0.8 in the interval of 2-5 GHz. Furthermore, the incident angle and polarization dependence of the wheel resonator based metamaterial absorber and harvester is also investigated and it is observed that the structure has both polarization and incident angle independent frequency response with good absorption characteristics in the entire working frequency band. Hence, the suggested design having good absorption, polarization and angle independent characteristics with wide bandwidth is a potential candidate for future energy harvester using wireless communication frequency band.

Low temperature crystallization of amorphous silicon by gold nanoparticle Karaman, M.; AYDIN, MURAT; Sedani, S. H.; ERTÜRK, KADİR; Turan, Raşit (Elsevier BV, 2013-08-01) Single crystalline Si thin film fabricated on glass substrate by a process called Solid Phase Crystallization (SPC) is highly desirable for the development of high efficiency and low cost thin film solar cells. However, the use of ordinary soda lime glass requires process temperatures higher than 600 degrees C. Crystallization of Si film at around this temperature takes place in extremely long time exceeding 20 h in most cases. In order to reduce this long process time, new crystallization techniques such a...
Realization of polarization-angle-independent fishnet-based waveguide metamaterial comprised of octagon shaped resonators with sensor and absorber applications Sabah, Cumali (Springer Science and Business Media LLC, 2016-05-01) A new fishnet-based waveguide metamaterial structure for the microwave region is introduced and investigated both numerically and experimentally. The proposed model is designed and fabricated on both sides of the substrate and exhibits strong metamaterial behavior (such as negative material parameters: i.e. negative permittivity, negative permeability, and negative index of refraction) at the resonance. Only one single slab is used in the simulation and experiment which provides a reduction in the number of...
Solvent selection for fabrication of low temperature ZnO electron transport layer in perovskite solar cells Ahmadi, S. Hamideh; Ghaffarkani, Mashhood; Ameri, Mohsen; Safari, Nasser; Mohajerani, Ezeddin (Elsevier BV, 2020-08-01) Zinc Oxide (ZnO) with an easy synthesis method, low processing temperature, and high charge carrier mobility has been considered as a proper electron transport layer (ETL) for perovskite solar cells. Herein, we investigate the effect of the most common solvents for the preparation of ZnO and investigate their application as ETL for PSC. ZnO layers were prepared from three different solvents 2-methoxyethanol (2ME), isopropyl alcohol (IPA) and ethanol. A complete investigation of the structural, morphological...
Trapping center parameters of TlGaSe2 layered crystals Yuksek, NS; Kavas, H; Hasanlı, Nızamı; Ozkan, H (Elsevier BV, 2004-02-15) Thermally stimulated current measurements are carried out on as-grown TlGaSe2 layered single crystals in the temperature range of 90-220 K with various heating rates. Experimental evidence is found for the presence of two trapping centers with activation energy 98 and 130 meV. The retrapping process is negligible for these levels, as confirmed by good agreement between the experimental results and theoretical predictions of the model that assumes slow retrapping. The calculation yielded 2.3 x 10(-24) and 1....
Carbon content influence on the optical constants of hydrogenated amorphous silicon carbon alloys Akaoglu, B.; Sel, K.; Atilgan, I.; Katircioglu, B. (Elsevier BV, 2008-04-01) Hydrogenated amorphous silicon carbon alloys (a-Si1-xCx:H) with different carbon contents are deposited by a plasma enhanced chemical vapor deposition (PECVD) system with different hydrogen diluted ethylene (C2H4) concentrations at two power densities of 30 and 90 mW/cm(2). First, the carbon and hydrogen configurations and their relative concentrations in these films are investigated in details by IR spectroscopy. Then, the ultraviolet/visible transmittance spectroscopy and a relevant characterization softw...
