  • Photovoltaic ultraviolet sensor
    Patent number: 7973379
    Abstract: A photovoltaic ultraviolet sensor comprises a zinc oxide single crystal substrate. On the +c face of the zinc oxide single crystal substrate, an ultraviolet receiver is formed. The exemplary ultraviolet receiver includes a Schottky electrode which, when receiving ultraviolet rays, produces a voltage in cooperation with the zinc oxide single crystal substrate. The ultraviolet sensor does not have any sensitivity to the visible rays. The ultraviolet sensor has a relatively fast response of several microseconds.
