Self-powered UV photodetector based on self-assembled CuO and spin-coated ZnO heterostructure
Source abstract
Abstract
Environmentally benign sustainable development can be realized only by meeting our energy demands through devices that can operate by taking energy from their surrounding environment. Self-assembled nanostructured CuO on copper ribbon and spin-coated ZnO thin films were optimized for engineering a self-powered UV photodetector in this work. We optimize the thickness of the ZnO and CuO thin films and subsequently the concentration of the alkaline electrolyte KOH to deliver a self-powered UV photodetector which exhibits an ON/OFF ratio of 505, photosensitivity of ~ 3433%, responsivity of ~ 84 mAW−1 and an excellent incident photon to current conversion efficiency of ~ 30% at 360 nm. We demonstrate the actuation of the UV photodetector by integrating the cells and switching on red and green LEDs.
