NPP Kvant

129626, Russia, Moscow The 3-rd Mytischinskaya, 16


Solar Cells and Arrays of Space Application

Space PV:

  • Activity on PV started in NPP Kvant for spacecrafts in 1957
  • The first PV SA for SC was developed in 1958 (on 3-d artificial earth satellite)
  • For today Kvant developed and manufactured nearly 2000 SA for SC

SA Application by NPP Kvant Developments:

  • Orbital station: Salut, Mir, ISS series
  • Automatic inter-planet spacecrafts: Venus, Mars, Fobos
  • Automatic inter-planet station Venus
  • Moon Rover-1, Moon Rover-2

Kvant Modern Projects in Space PV:

  • ISS: Russian segment consisting of modules Zarya and Zvezda with bifacial sensitivity SC
  • Large GEO platforms (Sesat, Expresses A&AM, Kazsat and other)
  • SC for remote Earth probing and meteorology (Monitor-E, Meteor-3 and others)
