Solution-processed metal-oxide semiconductors such as zinc oxide are now widely used in various energy harvesting devices such as organic solar cells and perovskite solar cells. However, since the oxide semiconductors can also show a high response to light illumination and possess persistent photoconductivity (PPC), it is important understand the photo carrier generation and decaying properties of oxide semiconductors. Here, we investigate the photoconductivity and photo-decaying porperties of various oxide semiconductor materials and structures such as indium gallium zinc oxide (IGZO), and a double-layered IZO/IGZO structure to identify the influence of channel materials and structures on the photocurrent and relaxation time of the device. |
