ABSTRACT:
A gas sensor comprises a photovoltaic cell which, upon exposure to light, develops a photovoltage or photocurrent which varies as a function of the type of gas sorbed. The cell includes in order a conductor, an N-type light-absorbing semiconductor, and a thin light-transmitting gas-absorbing metal Schottky layer having electrical properties which vary with the type of gas sorbed therein.
