  • The light absorption coefficient of sunlight is high, which is the most efficient among thin film solar cells.
  • The thickness of the light-absorbing layer material is several μm, and consumption of raw materials is very low.
  • Continuous processes are possible, which can lower the manufacturing cost.
  • It has advantages in terms of high durability and long-term stability.

Lightweight and flexible CIGS thin film solar cells

  • A CIGS thin film solar cell is manufactured on a lightweight flexible substrate such as a metal sheet or a plastic film.
  • It has a relatively high power ratio per weight.
  • When configuring a module using this, it has strengths in terms of installation place, construction method, and cost.
    • It can be installed in curved and heavy loads such as canopy, air dome, curtain, and vinyl greenhouse.
    • It can be conveniently constructed by attaching without installing a separate structure.
  • It has advantages in terms of high durability and long-term stability.
