Efficiency Enhancement of Solar Cell Using Metamaterials

In this work, Photovoltaic (PV) cell model with high absorption efficiency is introduced. The proposed four layer PV cell model consists of antireflection coating (ARC) layer on glass based and covered by metamaterial (MTM) bounded by air. The effect of the refractive index of MTM as well as the effect of the incident angle on the reflectance are considered. Results showed that the reflectance of the PV can be controlled by changing the reflectance index of MTM as well changing the incident angle.
