Planar superstrate CuInS2 (CIS) solar cell devices are fabricated using totally solution-processed deposition methods. A titanium dioxide blocking layer and an In2S3 buffer layer are deposited by the spray pyrolysis method. A CIS2 absorber layer is deposited by the spin coating method using CIS ink prepared by a 1-butylamine solvent-based solution at room temperature. To obtain optimum annealin...

The paper proposes a high gain, metamaterial based super wideband (SWB) antenna. SWB antenna has two inverted U slots which are responsible for notches at 3.5 GHz and 5.5 frequencies. A flower-shaped slot is etched from the radiator to obtain characteristics. dimensions of 30×35 ×1.5 mm3 with FR4 substrate. frequency bandwidth 3.1 - 15 S11 < -10dB. unit cell designed simulated permittivity perm...
