Dual-band perfect metamaterial absorber for solar cell applications

Rufangura, Patrick
Sabah, Cumali
The efficiency of solar photovoltaic (PV) cells has been one of the major problems impeding its global adoption as one of the sustainable substitutes to fossil fuel based technologies. Metamaterial (MTM) based solar cells offer an opportunity towards increasing the system efficiency by enhancing the total absorbed solar radiation incident on this device. In this study, a nanostructure-based MTM perfect absorber has been designed and simulated. By adjusting geometrical parameters and MTM structure properties, nearly perfect dual-band absorptions have been obtained with 99.99% and 99.90% absorption at 543.75 THz and 663.75 THz, respectively. The proposed structure is simple and more flexible for scaling, which helps achievement of multiple-band absorption. Implementation of the intended MTM structure can effectively lead to the realization of more efficient PV solar cells.

Rufangura, Patrick; Sabah, Cumali; Sustainable Environment and Energy Systems (2015-8)
Global adoption of solar photovoltaic (PV) cells as a sustainable substitute to fossil fuel technologies has been impeded by its low efficiency. Generally, efficiency of these devices strongly depends on their ability to absorb radiations of electromagnetic waves incident on them. Their low absorptivity provides a challenge. Metamaterials (MTM) based solar cells offer an opportunity for increasing the system efficiency by enhancing the total absorbed solar radiation incident on solar PV cells. In this thesi...
Multiband Metamaterial Absorber Design Based on Plasmonic Resonances for Solar Energy Harvesting
Mulla, Batuhan; Sabah, Cumali (2016-10-01)
A new metamaterial absorber is designed and characterized numerically for the harvesting of solar energy. The design is composed of three layers in which the interaction among them gives rise to the plasmonic resonances. The main operation frequency range of the proposed structure is chosen to be the visible regime. However, the design is also analyzed for the infrared and ultraviolet regimes. In order to characterize the absorber, some parametric studies with respect to the dimensions of the structure are ...

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...

Currently, solar energy is promising the primary source of renewable energy that has a great potential to generate power for an extremely low operating cost when compared to already existing power generation technologies. Increasing the efficiency of solar cells is a major goal and the prominent factor in photovoltaic system research. Current triple junction solar cells reach 30% and the next generation will bring 35% in 5 years to peak at 40%. These cells are used in space environment and in terrestrial sy...
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...
