The electrode of CdSe nanorods displayed photocurrent density of 2.1 mA/cm 2 whereas the Au core CdSe nanoflower exhibited 4.6 mA/cm 2 corresponding to a 119% increase during photoelectrochemical cell performance. Both electrodes showed prompt response to the on/off cycles of light, the photocurrent gain (I Photon /I dark ) in CdSe nanorods is 124.7, while the value is 223.3 for Au/CdSe nanoflower, calculated from the growth-decay curves. Photoresponse time was dramatically improved for Au/CdSe nanoflower samples due to increasing in 66% incident photon-to-current emission. Electron lifetime of 21.63 and 48.71 ns was observed for the electrode of CdSe nanorods and Au/CdSe nanoflowers respectively. The prolonged electron lifetime in the case of the electrode of Au/CdSe nanoflowers was responsible for improving charge separation and as a consequence, higher photocurrent generation. © 2018, Springer Nature Switzerland AG.enAu/CdSeHeterostructureNanoflowerPhotocurrentPhotoelectrochemical cellsArticlehttps://link.springer.com/article/10.1007%2Fs13404-018-0247-y
