photovoltaic detector
  آشکارگر ِ شید-ولتایی  
âškârgar-e šidvoltâyi
Fr.: détecteur photovoltaïque  

A detector usually constituted by a p-n junction. Upon irradiation, the electron-hole pairs which are created, are immediately separated by the strong electric field across the junction, and a current is generated, which is proportional to the number of incident photons per second.
