The use of bifacial cells as a frequency selective surface is proposed in this paper. The lack of the homogeneous rear side metallization and the periodicity of the finger grid contacts enable the bifacial cell structure to act as a wire-grid polarizer allowing transmission of radio waves of certain frequencies and polarizations. A fullwave integral-equation based electromagnetic simulator was used to determine the transmission loss of a theoretical bifacial cell with mirrored grid finger contacts and various silicon conductivities over the frequency range 2 to 5 GHz.
