We design, characterize, and analyze a new kind of metamaterial (MTM) absorber (MA) in difierent frequency regions for the solar cell applications. This MTM based structure is particularly presented in a range of the solar spectrum in order to utilize the solar energy efiectively. The proposed MTM based solar cell provides perfect absorption for both infrared and visible frequency ranges and can be used for the realization of more e-cient new solar cells. The structure is also tested in terms of the polarization angle independency. The suggested MA has a simple conflguration which introduces ∞exibility to adjust its MTM properties to be used in solar cells and can easily be re-scaled for other frequency ranges. Our experimental results in microwave frequencies conflrm the perfect absorption for the resonance frequency and agree with the simulation results. This means that the developed MA for solar cells will ofier perfect absorption in infrared and even in visible frequencies.
