The present investigation describes that the iron(Fe)doped ZnSe hexagonal nanorods were successfully synthesized via chemical synthesis specifically galvano static mode of electrode position and addition of Fe in order to improve the PEC performance of ZnSe electrodes using a galvanostatic mode.These crystalline Fe doped ZnSe hexagonal nanorods electrodes are characterized by X-ray diffraction(XRD),field emission scanning electron microscopy (FESEM),and optical properties,such as UV–vis spectroscopy, photoluminescence spectroscopy,electrochemical impedance spectroscopy (EIS),Raman spectroscopy and photoelectrochemical properties.It is seen that at 5% Fe doped ZnSe hexagonal nanorods show the open circuit voltage(Voc) was100mV,and shortcircuit current (Isc) was110 μA.The observed fill factor and efficiency were found to be 44% and 0.15%,respectively.
