Enhanced Absorption of Solar Cells by Graphene-Based Nano-Antenna Array
Abstract
A novel graphene based nano-antenna array is designed to increase the absorption of sunlight in silicon wafers of solar cells. The unit cell of array is composed of two coupled particles. Particles are graphene nano-bar and nano square ring placed at the middle of a silicon substrate with the thickness of 30nm. The former performs as electric and the latter as magnetic resonating particles at visible light frequency range. First, the two resonating particles are considered solely. It is shown that their absorption is about 40% at wavelength near 643 and 626nm respectively. Next they are considered together and the coupling is investigated. It is observed that plasmonic hybridization represents how graphene particles behave next to each other at visible region. An absorption of almost 80% of incident light is achieved by resonating particles. It is also shown that metallic nano-particles do not affect the electromagnetic characteristic.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
