NANO-PARTICLE PHOTO SENSOR AND FABRICATION METHOD THEREOF

摘要

PURPOSE: A nano particle photo sensor is provided to improve a photo electric property by forming a photosensitive layer made of nano particles of which conductivity is changed according to light absorption. CONSTITUTION: Two electrodes(11a,11b) which mutually faces are formed on a substrate(10). A photosensitive layer(20) is formed on the electrode. A transparent protection layer(21) is formed on the photo sensitive layer. The electrode and the light photo sensitive layer are ohmic-contacted. The substrate supports the photo sensitive layer.
