Nanorods (NRs) of crystalline ZnO coated with thin layers TiO$_2$(ZnO@TiO$_2$) were fabricated the help spin coating technique followed by hydrothermal method. Scanning electron microscopy (SEM) and X-ray diffraction analysis confirms morphology structural stability as-prepared NRs. The optical band gaps NRs estimated, a clear blue shift toward UV region has been detected. When light falls on d...

Dye sensitized solar cells have proven its potential as affordable, green method of turning energy into electrical energy. This article presents an extensive comparative study on dye with two types transport layers made ZnO nanorods and TiO2 mesoporous film, wherein bacterial pigment extracted from microorganism Serratia nematodiphila strain B2 is employed a sensitizer. For performance enhancem...
