A new broadband absorber is investigated for the entire frequency domain of solar light (infrared, visible light and ultraviolet). While current absorbers in the literature have limited operation frequencies, investigated structure has a wide bandwidth and a perfect absorptivity (99% at nearly all operation frequencies). The proposed metamaterial absorber has ultra-broadband, angle-insensitive, polarisation-independent characteristics with a different conventional pyramid shape. Whereas other pyramid or truncate pyramid-shaped multi-layered metamaterial absorber (MA) are composed of multi-layered dielectrics and metal combinations, the proposed structure has only three layers. As a result of exhibiting perfect absorption characteristic, the proposed structure is a new candidate for energy harvesting applications in solar energy collection.

Thin film (6,5) semiconducting single-walled carbon nanotube metamaterial absorber for photovoltaic applications Obaidullah, Madina; Esat, Volkan; Sabah, Cumali (2017-12-01) A wide-band (6,5) single-walled carbon nanotube metamaterial absorber design with near unity absorption in the visible and ultraviolet frequency regions for solar cell applications is proposed. The frequency response of the proposed design provides wide-band with a maximum of 99.2% absorption. The proposed design is also simulated with (5,4), (6,4), (7,5), (9,4), and (10,3) chiralities, and results are compared to show that the proposed design works best with (6,5) carbon nanotube (CNT) but also good for ot...
Dual-band high-frequency metamaterial absorber based on patch resonator for solar cell applications and its enhancement with graphene layers Ustunsoy, Mehmet Pasa; Sabah, Cumali (2016-12-05) In this paper, a dual-band high-frequency metamaterial absorber based on patch resonator is designed and analyzed for solar cells. In order to obtain a metamaterial absorber, metal-semiconductor-metal layers are combined. The results of the designed structure are shown in the infrared and visible ranges of solar spectrum. Structural parameters and dimensions of the device have a significant importance on the performance of the designed absorber. The simulations are carried out with full-wave electromagnetic...
Electromagnetic Energy Harvesting By Using Tunable Metamaterial Absorbers Bakir, Mehmet; KARAASLAN, MUHARREM; Dincer, Furkan; Akgol, Oguzhan; ÜNAL, EMİN; DELİHACIOĞLU, KEMAL; Sabah, Cumali (2015-05-19) In this study, electromagnetic (EM) energy harvesting by using metamaterial absorber is numerically explained. Operation frequency is 2.40 GHz since it is the industrical scientific and medical (ISM) band. This band is especially chosen due to most of the customer electronic devices are working in this band. Split ring resonator that have two splits on it used in this study, chip resistors are placed on these splits for wireless energy transfer to the devices. 83.6% efficient electromagnetic energy harvesti...
Surface texturing study with aluminum induced texturing method on soda-lime glass substrates for thin film solar cells Ünal, Mustafa; Turan, Raşit; Ünalan, Hüsnü Emrah; Department of Micro and Nanotechnology (2017) It is essential to employ an effective light trapping scheme to decrease the cost of produced solar electricity further in thin film solar cell technologies. There are several methods that can be used for light trapping and aluminum induced texturing (AIT) is one of them. The aim of this thesis study is to obtain highly effective light trapping interface via texturing of glass surface by AIT process. The resultant texture is affected by several parameters such as Al thickness, annealing time and temperature...
Near infrared interference filter design and the production with ion-assisted deposition techniques Aydoğdu, Selçuk; Esendemir, Akif; Department of Physics (2012) Near infrared region (NIR) of the electromagnetic spectrum (EM) is defined as 700nm to 1400nm wavelength interval by International Commission on Illumination(CIE). This wavelength interval is extensively used for target acquisition, night vision, wireless communication etc. Therefore, filtering the desired portion of EM spectra becomes a need for that kind of applications. Interference filters are multilayer optical devices which can be designed and produced for the desired wavelength intervals. The product...
