Solar Junction Triple Junction Solar Cell (TTJ and SMCC)
Solar Junction’s triple junction solar cell products (TTJ and SMCC) are three-junction compound semiconductor devices designed to meet the requirements of our CPV and Space Power customers. Typical cell sizes range from 0.5 mm x 0.5 mm to 2 cm x 2 cm with mean production efficiencies exceeding 30% AM0 and 42% under concentration.

The TTJ terrestrial product provides the following benefits over the competition:

  • Highest efficiency, commercially available CPV solar cell in the world.
  • Proprietary lacttice-matched architecture ensures long-term reliability for 25 to 30 years ‘on sun’.
  • Designed and proven to operate at concentrations beyond 4000 suns.
